what is matter made of?

Answer:

answer is solid

Explanation:

solid always is hard and can never change yet liquid and gas can move

The term 'phase' refers to the state of matter staying the same, and there are three main phases: solid, liquid, and gas. In a solid, the particles are in fixed positions and maintain a fixed volume and shape. The law of conservation of matter states that the total amount of matter remains constant during phase transitions.

The term that means the state of matter stays the same is phase. Matter exists in one of three main states, namely solid, liquid, and gas. In the solid phase, atoms or molecules do not have enough energy to move past each other and are in fixed positions with strong intermolecular forces; thus, they maintain a fixed volume and shape. The liquid phase has atoms or molecules that are constantly in contact yet have enough energy to move freely relative to one another, allowing the liquid to take the shape of its container while maintaining a definite volume. The gas phase is characterized by particles that are separated by relatively large distances and that fill the volume of their container.

In any closed system, the law of conservation of matter dictates that no detectable change in the total amount of matter occurs during the transition from one phase to another. Thus, when matter undergoes a phase change, its state may alter, but the total quantity of matter remains constant within a given system.

It is the process of converting free nitrogen into nitrogenous compounds .

Let us study about it :

In nature there are certain plants called as leguminous plants .These plants have nitrogen fixing bacteria called as rhizobium  in their root nodules .

This bacteria can convert free atmospheric nitrogen into ammonia .

Then this ammonia with the help of bacteria nitrosomonas and nitrobacter gets converted into  nitrites and nitrates .

Then these nitrites and  nitrates with the help of bacteria like pseudomonas gets converted back into free nitrogen ,

This cycle helps in enriching the soil and to maintain nitrogen percent constant in atmosphere ,

Hey There!:

Density = mass / volume

Density of helium in the blimp = 0.1786 kg/m³

Volume of helium in the blimp = 6.28 x 10⁹ mL

converting the volume in  m³ :

1 m³ -------------------------------- 1 x 10⁻⁶ m³

Volume( m³ ) -------------------- 6.28 x 10⁹

Volume  ( m³ ) =  ( 6.28 x 10⁹ ) x 1 /   ( 1 x 10⁻⁶ )

Volume ( m³ ) =  ( 6.28 x 10⁹ ) / ( 1 x 10⁻⁶ )

Volume ( m³ ) = 6280 m³

Therefore:

D = m / V

0.1786 = m / 6280

m = 0.1786 x 6280

m = 1121.608 g

converting in Kg :

1 kg ------------------ 1000 g

?? --------------------- 1121.608 g

mass = 1121.608 x 1 / 10000

mass = 1121.608  / 10000

mass = 1.12 x 10⁶ g

Hope that helps!

Final answer:

To find the mass of helium in the blimp, multiply the volume of helium ([tex]6.28 * 10^9[/tex] milliliters) by the density (0.1786 g/mL). This results in a mass of approximately [tex]1.121768 * 10^9[/tex] grams.

Explanation:

The question asks us to calculate the mass of the helium in the blimp given its volume and density. To find the mass, you need to use the formula: mass = volume × density.

In this case, the volume of helium is 6.28 × [tex]10^9[/tex] milliliters and the density of helium is 0.1786 grams per milliliter. So, you would calculate the mass as follows:

mass = 6.28 × [tex]10^9[/tex] mL × 0.1786 g/mL

mass = 1.121768 × [tex]10^9[/tex]grams

The mass of helium in the blimp is therefore approximately 1.121768 × [tex]10^9[/tex] grams.

Answer:

                     M.Mass = 120 g/mol

Explanation:

Data Given:

                  Volume = V = 0.0650 L

                  Temperature = T = 547 °C = 820.15 K

                  Pressure = P = 70.5 kPa = 0.695 atm

                  Gas Constant = R = 0.082057 L.atm.mol⁻¹.K⁻¹

Formula Used:

                        Assuming that the gas is ideally then according to ideal gas equation,

                                   P V = n R T

Solving for n,

                                   n = P V / R T

Putting Values,

    n = (0.695 atm × 0.0650 L) ÷ (0.082057 L.atm.mol⁻¹.K⁻¹ × 820.15 K)

    n = 6.71 × 10⁻⁴ moles

Now, Knowing that,

                                  Moles  =  Mass / M.Mass

Or,

                                  M.Mass = Mass / Moles

Putting values,

                                  M.Mass = 8.06 × 10⁻² g / 6.71 × 10⁻⁴ mol

                                  M.Mass = 120 g/mol

102 grams of ammonia is formed when 3 moles of nitrogen and 6.7 moles of hydrogen reacts.

Explanation:

The equation given is of Haeber's process in which the nitrogen is limiting factor in the ammonia formation and hydrogen if in excess gets delimited.

We know that 1 mole of Nitrogen gives 2 moles of ammonia.

We have 3 moles of nitrogen here,

So, 6 moles of ammonia will be form

so from the formula

no of moles=mass/atomic mass

           mass= no. of moles*atomic mass

                     = 6*17

                       = 102 grams of ammonia will be formed.

So, 6 moles or 102 grams of ammonia is formed when 3 mole of nitrogen and 6.7 mole of hydrogen reacts.

Answer:

A.  it is the lowest at low temperatures

Explanation:

At low temperature the kinetic energy of a molecule is low. The kinetic energy is directly proportional to the temperature of the molecule. The kinetic energy of a molecule increases with the increase in the temperature that energize the molecules of a substance and makes them to move faster than before.

As the kinetic energy is proportional to temperature so it does not increase with decrease in the temperature (low temperature). The kinetic energy varies with the change in the temperature and it is not same at all temperature. The kinetic energy is highest at high temperature. Thus, option A is correct.

It is dangerous to combine alcohol and other drugs because Combining them may cause a more intense effect than just taking one drug at a time and the effect can be unpredictable.

Explanation:

hope this helps

brainliest is appreciated... :}

Final answer:

Combining alcohol with other drugs is hazardous due to the increased risk of significant CNS depression, leading to serious consequences such as respiratory failure or death. Compounding tolerance and severe withdrawal symptoms highlight the dangers of physical dependence on these substances.

Explanation:

It is dangerous to combine alcohol and other drugs because such combinations can lead to additive or synergistic effects that intensify the impact on the central nervous system (CNS). For example, alcohol and barbiturates both depress the CNS, potentially resulting in enhanced sedative effects which may escalate to severe respiratory depression, coma, or death. Alcohol also impairs motor control, judgment, and cognitive functions, and when combined with other CNS depressants, these effects worsen, creating significant risk for injuries or fatal accidents.

Additionally, chronic alcohol consumption can lead to increased tolerance, meaning that higher doses are needed to achieve the same effect, which can be particularly dangerous when other substances are involved. Withdrawal symptoms from alcohol or other depressants can be severe and even life-threatening, requiring medical supervision during the detoxification process. This is indicative of the physical dependence that users of depressants could develop over time.

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.

The fourth one down

Explanation:

It is the only setup in which the units of "cm" and "in" cancel correctly and give the desired units of "ft."

The second one down has the correct units but the wrong conversion factor for converting centimetres to inches.

The student is asked to use dimensional analysis for unit conversion within the metric system, such as converting meters to centimeters using a ratio or conversion factor.

The question asks for the conversion of centimeters to fit, which appears to be a typo and should likely refer to converting measurements within the metric system. Specifically, the task involves applying dimensional analysis to convert lengths from one unit to another, such as meters to centimeters or vice versa.

Steps for Conversion Using Dimensional Analysis

Identify the provided measurement and its unit.

Determine the unit you need to convert to.

Set up a conversion factor, which is a ratio representing the relationship between two units.

Multiply the given measurement by the conversion factor to get the answer in the desired unit.

For example, to convert 1.5 meters to centimeters, you set up the proportion: 100 cm/1 m = x cm/1.5 m. By cross multiplying and solving the proportion, you find that x = 100 × 1.5 cm, which equals 150 cm.

0,5 mole

Explanation:

Because n = N/Nₐ, n(Rb) = 0,5 mole

One mole of every element contains 6,022045 × 10²³ atoms, so 3,01 × 10²³ atoms of rubidium is half mole.

To solve this we must be knowing each and every concept related to mole. Therefore, 3.01 x 0²³ atoms of rubidium contains 0.499moles.

A mole is merely a measuring unit. In reality, it is one of its International System of Units' seven foundation units. When current units are insufficient, new units are created.

Chemical reactions frequently occur at levels where employing grams would be inappropriate, but using absolute quantities of atoms/molecules/ions would also be misleading.

For all practical reasons, one mole of a substance in grams is nearly equal to 1 molecule for the compound per daltons.

Mathematically,

mole =given number of atoms ÷ 6.022×10²³(Avogadro number)

given number of atoms=3.01 x 0²³

substituting all the given values in the above equation, we get

mole =3.01 x 0²³ ÷ 6.022×10²³(Avogadro number)

        =0.499moles

Therefore, 3.01 x 0²³ atoms of rubidium contains 0.499moles.
