Answer:Iron(|||) Hydroxide
Explanation:Fe is iron and OH is hydroxide
Final answer:
Iron(III) hydroxide is the name of the compound Fe[tex](OH)_{3}[/tex], a reddish-brown precipitate formed by iron in the +3 oxidation state combining with hydroxide ions.
Explanation:
The compound with the chemical formula Fe[tex](OH)_{3}[/tex] is known as iron(III) hydroxide. It can also be referred to as ferric hydroxide. This compound is formed when iron ions in the +3 oxidation state (Fe³⁺) combine with hydroxide ions (OH⁻) in a 1:3 ratio, resulting in the reddish-brown precipitate that is represented by the formula Fe[tex](OH)_{3}[/tex]. The chemical reactions provided, such as Fe(OH)₃ (s) + 3Na⁺ (aq) + 3NO₃⁻(aq), highlight the chemical processes involving iron(III) hydroxide in various contexts. In the case of FeCl₃(aq) + NaOH(aq), when a solution containing iron and a hydroxide is mixed, a precipitate of iron(III) hydroxide forms along with the resulting sodium chloride.
The Calvin cycle converts ATP and NADPH to
a0
Answer:
The Calvin cycle converts ATP and NADPH to "convert CO2 to sugar".
Explanation:
When carbon dioxide reaches inside the leaf through pores called stomata in plants and spreads to the chloroplast stroma, it act as the location of Calvin cycle reactions where sugar is naturally produced.The light-independent processes are also called such reactions as they are not primarily guided by light.
The Calvin cycle processes can be separated into three main channels: carbon fixation, reduction, and starting molecule's regeneration as explained below:
Carbon Fixation: Six-carbon compound are generated in this step that bifurcate into two molecules (three-carbon compound) 3-phosphoglyceric acid (3-PGA), catalyzed by the enzyme rubisco or RuBP carboxylase/oxygenase.Reduction: In this phase of the cycle 3-PGA molecules are converted into glyceraldehyde-3-phosphate (G3P) i.e three-carbon sugar by using ATP and NADPH.Regeneration: Many G3P molecules are used to generate glucose, while others have to be recycled to recreate the acceptor RuBP.Are all individuals in a population of animals or a population of plants identical

Suppose the boy skipped his lunch for a day how will the hormones from his pancreasls help his body to cope wwhen his blood sugar level drops below normal
Answer:
The hormone glucagon secreted by the pancreatic cells cause the release of glucose from the body's storage.
Explanation:
The pancreas is an organ found inside the abdomen. This organ produces hormones such as:
InsulinGlucagonSomatostatinVasoactive intestinal peptideInsulin and glucagon are considered primary hormones secreted by the pancreas.
Upon skipping a meal, leading to a drop in blood sugar levels, glucagon is secreted by the pancreas. This hormone then acts on the liver to stimulate the conversion of stored up glycogen present in the liver into glucose. This produced glucose is then released into the blood stream, availing the boy glucose for energy.
The hormone of glucagon that is released by pancreas helps the body cope when the blood sugar level drops below normal.
Role of GlucagonThe hormones from his pancreas release glucagon that helps the body to cope when his blood sugar level drops below normal because the body needs energy so it takes the sugar from the storage present inside the body. If blood sugar level falls too low, the pancreas releases glucagon which tells the liver to make more glucose.
Glucagon is a hormone that is responsible for the making of glucose from the stored energy in the body so we can conclude that the hormone of glucagon that is released by pancreas helps the body cope when the blood sugar level drops below normal.

what is a polar functional group?
I think this is the answer
Final answer:
A polar functional group is a cluster of atoms within a molecule that has polar preferences due to the uneven distribution of electrons, resulting in areas with partial positive and negative charges which enable it to participate in various chemical reactions and interactions with other polar substances, such as water.
Explanation:
A polar functional group is a specific grouping of atoms within a molecule that has a polarized distribution of charges, which means there is an uneven distribution of electron density. This polarity arises because of the presence of electronegative atoms like oxygen, nitrogen, or fluorine, which attract electrons more strongly than other types of atoms in the functional group. These groups have partial positive and negative charges at different points and are often involved in chemical reactions due to their ability to interact with other molecules and ions. A classic example of a polar functional group is the hydroxyl group (-OH), common in alcohols and known for being hydrophilic or water-loving, meaning it can form hydrogen bonds with water and dissolve easily in it. Other examples include carbonyl groups (C=O) in ketones and aldehydes, carboxyl groups (-COOH) in amino acids and fatty acids, and phosphate groups (-PO4) often found in DNA and ATP.

Look at photo for proof.
A hydrocarbon would be a good fuel in terms of enthalpy if it produces a lot of energy when burned and has a large negative enthalpy of combustion. The correct option is (B).
Explanation:In terms of enthalpy, a good fuel would be one that releases a large amount of energy when burned. This means that burning hydrocarbons should produce a lot of energy (option B).
Breaking carbon-hydrogen and carbon-carbon bonds in hydrocarbons actually requires energy, so it doesn't contribute to the enthalpy of combustion (option C).
The enthalpy of combustion is defined as the heat released when one mole of a substance is burned completely in oxygen. Since the combustion of hydrocarbons releases a large amount of heat energy, the enthalpy of combustion is a large negative value (option D).

How to balance K2SO4+BaCl2= BaSO4+KCl
Answer:
The answer is K2SO4 + BaCl2 = BaSO4 + 2KCl
Explanation:
First, you can do it by looking how many chlorine is being used. As you can see that 2 chlorine is being used so you are sure that 2 chloine is in the right side.
Secondle, there are also 2 potassium in the left side so there must be also 2 potassium in the right side.
K2 + Cl2 = K2Cl2 (to make it beautiful)
= 2KCl (you can take out 2, just similar to factorisation)
(Hope this can help)
Final answer:
The balanced equation for the reaction between K2SO4 and BaCl2 to produce BaSO4 and KCl is K2SO4(aq) + BaCl2(aq) → BaSO4(s) + 2KCl(aq). BaSO4 is an insoluble precipitate, and the balance is achieved by having 2 moles of KCl in the products to match the potassium atoms.
Explanation:
To balance the chemical equation K2SO4(aq) + BaCl2(aq) → BaSO4(s) + KCl(aq), we need to ensure that the number of atoms of each element on the reactant side is equal to the number on the product side. Initially, we have 2 potassium (K) atoms on the reactant side and only 1 potassium atom on the product side. We also have 1 barium (Ba) atom, 1 sulfate (SO4) group, 2 chloride (Cl) atoms on the reactant side, and the same on the product side. To balance the equation, we simply need to adjust the coefficient in front of KCl to 2, as shown in the balanced equation:
K2SO4(aq) + BaCl2(aq) → BaSO4(s) + 2KCl(aq)
By doing this, we ensure that the number of potassium atoms is now 2 on both sides, and the chlorides are also balanced with 2 atoms on each side. The product BaSO4 is insoluble and will form a precipitate, while the other products remain in solution.

(gains electrons) .
This transfer makes the sodium atoms acquire (positive) charge and phosphorous acquire (negative) charge .
As a result, the sodium and phosphorus atoms strongly (attract) with
each other.
Explanation:
In the paragraph about the formation of sodium phosphide: Electrons are transferred from atoms of sodium to atoms of phosphorous. This transfer makes the sodium atoms acquire positive charge and phosphorous acquire negative charge. As a result, the sodium and phosphorus atoms strongly attract each other.
Between the phosphorous (P) and sodium (Na) atoms, electron transfer occurs to generate sodium phosphide. When phosphorus receives electrons from sodium, sodium loses electrons, leaving sodium ions (Na⁺) with a positive charge and phosphide ions (P³⁻) with a negative charge as a result.
The oppositely charged ions are attracted to one another strongly electrostatically as a result of this charge difference. This kind of link, referred to as an ionic bond, results in the creation of sodium phosphide (Na₃P), a stable molecule in which several sodium ions are completely encircled by phosphide ions, solidly keeping them together in a crystal lattice structure.

Which two elements in group 14 on the periodic table most likely to be malleable and good conductors of electricity
Answer:
Tin & Lead
Explanation:
They are metals and can conduct electricity because their outer electrons are not localized, i.e., they are not bound to specific atoms.
The energy level of electrons in the "conduction band" overlaps that of valence electrons. These electrons are more like a cloud dispersed throughout the piece of metal so that when an electric field is applied, they can move around.
The two element in 14th group of periodic table most likely to be malleable and good conductors of electricity are lead and tin. They are mostly existing in metallic state.
What are conductors ?Conductors are materials that can easily pass electricity through it at normal temperature. Metals are all good conductors. In addition metals have some peculiar features such as malleability, ductility, luster etc.
14th group elements are carbon family. In this group, carbon at normal temperature exists as gas. Silicon and germanium are semiconductors. Lead and tin are metallic in nature and they are malleable as well.
Lead and tin can be shaped and sized as desired and they are used in various electronic devices also because they are good conductors at metallic state. Therefore, tin and lead are the two elements.

what mass in grams, of aluminum fins could 3088J of energy heat from 14.77 degrees C to 26.31 degrees C? Aluminum has a specific heat of 0.897/J (g degrees Celsius)?
Answer:
298.32 grams
Explanation:
Amount of energy required by known amount of a substance to raise its temperature by one degree is called specific heat capacity.
The equation used for this problem is as follow,
Q = m Cp ΔT ----- (1)
Where;
Q = Heat = 3088 J
m = mass = ??
Cp = Specific Heat Capacity = 0.897 J.g⁻¹.°C⁻¹
ΔT = Change in Temperature = 26.31 °C - 14.77 °C = 11.54 °C
Solving eq. 1 for m,
m = Q / Cp ΔT
Putting values,
m = 3088 J / (0.897 J.g⁻¹.°C⁻¹ × 11.54 °C)
m = 298.32 g
