Answer:
Explanation:
A. Metals are shiny, usually solid at room temperature, malleable, ductile, and highly conductive. In contrast, ionic compounds are brittle. Molecular compounds are often gases at room temperature.
b. Metals have very few valence electrons. Their outermost p-orbitals are empty. This allows their electrons (including those from their d-orbitals) to move freely between metal atoms. The movement of electrons is electricity, so this mobile "sea of electrons" is what causes metals' conductivity.

Which of the following changes to a pipe would increase the conductance by a factor of 12?
A. Quadrupling the length and tripling the radius.
B. Reducing the length by a factor of and doubling the radius.
C. Tripling the length and reducing the radius by a factor of .
D. Reducing the length but a factor of and doubling the radius.
C. Tripling the length and reducing the radius by a factor of 2 is the change to a pipe would increase the conductance by a factor of 12.
Explanation:
As we know that the resistance is directly proportional to the length of the pipe and it is inversely proportional to the cross sectional area of the pipe.
So it is represented as,
R∝ l /A [ area is radius square]
So k is the proportionality constant used.
R = kl/A
Conductance is the inverse of resistance, so it is given as,
C= 1/R.
R₁ = kl₁ / A₁
R₂ = kl₂/A₂
R₂/R₁ = 1/12 [∵ conductance is the inverse of resistance]
= l₂A₁ / l₁A₂
If we chose l₁/l₂= 3 and A₂/A₁= 4 So R₂/R₁= 1/3×4 = 1/12
So tripling the length and reducing the radius by a factor of 2 would increase the conductance by a factor of 12.
Answer:
Reducing the length by a factor of 1/3 and doubling the radius.

Chemical reaction to form products this chemical equation represents one such reaction the coefficient for one of the reactants or products is incorrect which part of the chemical equation is incorrect. 2c⁴h¹⁰ + 10o² -> 8co² +10h²o
Answer:
In a chemical equation, chemicals that react are the reactants, while chemicals that are produced are the products/by products. Both sides of the equation must be balanced.
\
Explanation
When writing a chemical equation, reactants reacts to produce products. For example in the equation for formation of water, hydrogen combines with oxygen as 2H₂ +O₂→2H₂O where the first part before the arrow represent the reactants and the next part after the arrow are the products. Reactants are on the left where as products are on the right.Coefficient 2, in this cases is used for balancing the equation
The coefficient of the reactant diatomic oxygen (O2) is incorrect in the provided chemical equation. The corrected equation for the combustion of butane is 2C4H10 + 13O2 -> 8CO2 +10H2O.
Explanation:The given equation is 2C4H10 + 10O2 -> 8CO2 +10H2O. The coefficient of diatomic oxygen (O2), a reactant, is incorrect. It's essential to balance the number of atoms on both sides of a chemical equation to abide by the law of conservation of matter. The correct equation should be 2C4H10 + 13O2 -> 8CO2 +10H2O. This represents the combustion of butane.

What is the mass of a nitrogen dioxide molecule?
The mass of a nitrogen dioxide (NO2) molecule is approximately 46 atomic mass units (amu) as per the concept of molar mass.
Molar mass of a compound or a molecule is defined as the mass of the elements which are present in it.The molar mass is considered to be a bulk quantity not a molecular quantity. It is often an average of the of the masses at many instances.
The molecular mass and formula mass are used as synonym for the molar mass.It does not depend on the amount of substance which is present in the sample.It has units of gram/mole.
Molar masses of an element are given as relative atomic masses while that of compounds is the sum of relative atomic masses which are present in the compound.This is because the atomic masses of nitrogen is 14 amu and that of nitrogen is 16 amu, respectively. Since there are two oxygen atoms and one nitrogen atom in an NO₂ molecule, the total mass is calculated as follows:
[tex]2\times16+1\times14=46 \ amu[/tex]

why does hydrogen only burn at the mouth of the bottle?
What is the pressure generated in a 10 liter container at 300K when
68 gram of H2O2 decomposes?
please I only have 30 minutes left
Answer:
Pressure = 2.45 atm
Explanation:
The balance chemical equation for the decomposition of hydrogen peroxide is as follow;
2 H₂O₂ ₍aq₎ → 2 H₂O ₍l₎ + O₂ ₍g₎
Step 1: Calculate Moles of H₂O₂ as;
Moles = Mass / M.Mass
Moles = 68.0 g / 34.01 g/mol
Moles = 1.99 moles
Step 2: Calculate Moles of O₂ gas produced:
According to equation,
2 moles of H₂O₂ produced = 1 mole of O₂
So,
1.99 moles of H₂O₂ will produce = X moles of O₂
Solving for X,
X = 1.99 mol × 1 mol / 2 mol
X = 0.995 moles of O₂
Step 3: Calculate pressure exerted by O₂ gas as;
According to ideal gas equaton,
P V = n R T
Or,
P = n R T / V
Putting values,
P = 0.995 mol × 0.08205 L.atm.K⁻¹.mol⁻¹ × 300 K / 10 L
P = 2.45 atm

Find the new volumes if the values given below change to STP (273 K and 101.3 kPa)...
(a) 24.6 L at 25°C and 10 atm
Answer:
3. V = 0.2673 L
4. V = 2.4314 L
5. V = 0.262 L
6. V = 2.224 L
Explanation:
3. assuming ideal gas:
PV = RTn∴ R = 0.082 atm.L/K.mol
∴ V1 = 225 L
∴ T1 = 175 K
∴ P1 = 150 KPa = 1.48038 atm
⇒ n = RT/PV
⇒ n = ((0.082 atm.L/K.mol)(175 K))/((1.48038 atm)(225 L))
⇒ n = 0.043 mol
∴ T2 = 112 K
∴ P2 = P1 = 150 KPa = 1.48038 atm
⇒ V2 = RT2n/P2
⇒ V2 = ((0.082 atm.L/K.mol)(112 K)(0.043 mol))/(1.48038 atm)
⇒ V2 = 0.2673 L
4. gas is heated at a constant pressure
∴ T1 = 180 K
∴ P = 1 atm
∴ V1 = 44.8 L
⇒ n = RT/PV
⇒ n = ((0.082 atm.L/K.mol)(180 K))/((1 atm)(44.8 L))
⇒ n = 0.3295 mol
∴ T2 = 90 K
⇒ V2 = RT2n/P
⇒ V2 = ((0.082 atm.L/K.mol)(90 K)(0.3295 mol))/(1 atm)
⇒ V2 = 2.4314 L
5. V1 = 200 L
∴ P1 = 50 KPa = 0.4935 atm
∴ T1 = 271 K
⇒ n = RT/PV
⇒ n = ((0.082 atm.L/K.mol)(271 K))/((0.4935 atm)(200 L))
⇒ n = 0.2251 mol
∴ P2 = 100 Kpa = 0.9869 atm
∴ T2 = 14 K
⇒ V2 = RT2n/P2
⇒ V2 = ((0.082 atm.L/K.mol)(14 K)(0.2251 mol))/(0.9869 atm)
⇒ V2 = 0.262 L
6.a) ∴ V1 = 24.6 L
∴ P1 = 10 atm
∴ T1 = 25°C = 298 K
⇒ n = RT/PV
⇒ n = ((0.082 atm.L/K.mol)(298 K))/((10 atm)(24.6 L))
⇒ n = 0.0993 mol
∴ T2 = 273 K
∴ P2 = 101.3 KPa = 0.9997 atm
⇒ V2 = RT2n/P2
⇒ V2 = ((0.082 atm.L/K.mol)(273 K)(0.0993 mol))/(0.9997 atm)
⇒ V2 = 2.224 L
The volume of a gas at different temperatures while keeping pressure constant can be calculated using Gay-Lussac's law. For the first question, we use the initial volume and temperature to find the final volume when the temperature changes to 112 K, while pressure remains constant.
The volume of a gas at different temperatures and pressures, while some variables are kept constant, can be calculated using the combined gas law when both temperature and pressure change, or Gay-Lussac's law when only temperature changes and pressure stays constant, or Boyle's law when only pressure changes and temperature stays constant.
For the first question: The initial conditions are a volume of 225 L at a temperature of 175 K, and we're asked to find the final volume at 112 K while keeping pressure constant.
Using Gay-Lussac's law: V1/T1 = V2/T2, we rearrange to solve for V2:
V2 = V1 * T2/T1
V2 = 225 L * 112 K/175 K
After performing the calculation, you find the new volume at 112 K.

8 oz bottle of Dr. Pepper made with imperial cane sugar (C12H22O11) contains 27 g of sugar in 236.6 mL of water. What is the molarity of the solution with respect to cane sugar?
Answer:
0.33M
Explanation:
Molarity is asking, in Laymens terms:
"If I took a litre of this stuff, how much stuff is gonna be in it?"
Diving deeper, we use litres instead of millilitres or nanolitres because that's usually what we're working with. We use moles rather than mass because mass varies; different substances have different molar masses, so describing something in g/L makes no sense if you're comparing two different solutions.
Anyway, go find the number of moles:
n=m/mm
n=27g/342.34g/mol
n=0.078870mol
The next question you've gotta ask yourself is:
What if I had a litre of it?
V = 0.2366L
M=n/V
M=0.078870mol/0.2366L
M=0.33M
The molarity of the Dr. Pepper made with imperial cane sugar is 0.334 M. This is calculated by first converting the mass of sugar into moles and the volume of water from mL to L, and then using these values in the molarity equation.
Explanation:To calculate the molarity of a solution, we can use the formula: Molarity (M) = moles of solute/liters of solution. To apply this to your question, we first need to convert the mass of cane sugar (C12H22O11) into moles. The molecular weight of cane sugar (C12H22O11) is approximately 342.3 g/mol. Therefore, 27 g of sugar is approximately equal to 0.0789 moles.
Next, we need to convert the volume of water from mL to L. Hence, 236.6 mL is equal to 0.2366 L. Now, we can use these values in our molarity equation: M = 0.0789 moles/ 0.2366 L = 0.334 M. Therefore, the molarity of the Dr. Pepper made with imperial cane sugar is around 0.334 M.

Which are characteristics of medusae?
are sessile, have tentacles, mouths open downward
swim freely, lack tentacles, mouths open upward
swim freely, have tentacles, mouths open downward
are sessile, lack tentacles, mouths open upward
The correct characteristics of medusae are: swim freely, have tentacles, mouths open downward.
Medusae are the free-swimming, jellyfish-like form of certain aquatic animals, typically found in the phylum Cnidaria. They are characterized by their ability to swim freely in the water, which distinguishes them from the sessile, or immobile, polyps that are another life stage of cnidarians. Medusae have tentacles that hang down from their bell-shaped bodies, which they use to capture prey. These tentacles are often equipped with stinging cells called nematocysts that help to immobilize their prey. The mouth of the medusa is located on the underside of the body, facing downward, and leads to a gastrovascular cavity where digestion takes place.
To summarize, the following are the characteristics of medusae:
- Swim freely: Medusae are capable of locomotion and can move through the water column.
- Have tentacles: They possess tentacles that extend from their bodies, which are used for capturing food.
- Mouths open downward: The mouth is situated on the ventral side of the medusa, facing downward, which is suitable for bringing captured prey into the gastrovascular cavity for digestion.
The other options listed do not accurately describe medusae:
- Are sessile: This is incorrect because medusae are free-swimming, not immobile.
- Lack tentacles: This is incorrect because tentacles are a defining feature of medusae.
- Mouths open upward: This is incorrect because the mouth of a medusa opens downward.

Explanation:
Final answer:
To express y in terms of x, you manipulate an equation to make y the subject, using substitution and algebraic manipulation for simple equations, or differentiation and implicit differentiation for more complex relationships.
Explanation:
To express y in terms of x, one typically manipulates a given equation or set of equations, solving for y to make it the subject. The process may involve various mathematical techniques, including substitution, algebraic manipulation, and differentiation when dealing with functions of multiple variables. An example of expressing y in terms of x can be seen in a simple linear equation, such as y = mx + b, where m is the slope and b is the y-intercept. In this case, y is already expressed in terms of x.
In more complex relationships, such as the nonlinear equation x + y = exp(xy), one might take a derivative with respect to x to get dy/dx and solve that differential equation for y in terms of x, considering implicit differentiation if necessary.
If one force on an object on an object is 5N upward and the other obect is 10N downward, what is the object's motion ?
Answer: It will move down
Explanation: Since there is an unbalanced force on the object its motion is directed on the side with the greatest amount of force.
Final answer:
With a net force of 5N downward, the object will accelerate downward.
Explanation:
If one force on an object is exerted 5N upward and another force is 10N downward, we can calculate the net force to determine the object's motion. By subtracting the upward force from the downward force, we get a net force of 10N - 5N = 5N downward. Since the net force is downward, the object will accelerate in the downward direction according to Newton's Second Law of Motion, assuming no other forces are acting on the object.
