Answer:

Their structure is related to their function.

Explanation:

Protein structure is related to their function. Therefore, the correct option is option D among all the given options.

Proteins are huge biomolecular and macromolecular structures made up of one or even more long amino acid residue chains. Proteins serve a wide range of roles inside animals, including catalyzing metabolic events, DNA replication, reacting to stimuli, provides support to organisms and cells including transporting chemicals.

Proteins differ largely in their amino acid sequence, which is determined by the genetic code from their genes and generally culminates with protein folding into such a particular 3D structure that dictates its function. Protein structure is related to their function.

Therefore, the correct option is option D.

If 30 grams of KCl is dissolved at 10°C, 14 g of KCl should be added to make a saturated solution at 60 °C.

A saturated solution is a solution in which there is so much solute that if there was any more, it would not dissolve. Its concentration is the same as the solubility at that temperature.

At 10 °C, the solubility is 31.2 g KCl/100 g H₂O.

30 g KCl × 100 g H₂O/31.2 g KCl = 96 g H₂O

At 60 °C, the solubility is 45.8 g KCl/100 g H₂O.

96 g H₂O × 45.8 g KCl/100 g H₂O = 44 g KCl

44 g - 30 g = 14 g

If 30 grams of KCl is dissolved at 10°C, 14 g of KCl should be added to make a saturated solution at 60 °C.

Given the data from the question, the mass of arsenic that contains 1.23×10²⁰ atoms is 0.0153 g

6.02×10²³ atoms = 1 mole of arsenic

But

1 mole of arsenic = 75 g

Thus, we can say that:

6.02×10²³ atoms = 75 g of arsenic

6.02×10²³ atoms = 75 g of arsenic

Therefore,

1.23×10²⁰ atoms = (1.23×10²⁰ × 75) / 6.02×10²³ atoms)

1.23×10²⁰ atoms = 0.0153 g of arsenic

Thus, 1.23×10²⁰ atoms is present in 0.0153 g of arsenic

The reaction rate is affected if the vitamin C is added in lower quantity due to lower amount of reactants.

If you added 40.0 mL of Vitamin C stock solution instead of 25.0 mL when preparing Solution, the reaction rate is affected because of the lower amount of reactant for the chemical reaction. If the reactants are present in larger amount then the products are also produced in large concentration.

So we can conclude that the reaction rate is affected if the vitamin C is added in lower quantity due to lower amount of reactants.

Answer:

The Bohr model show the protons in a carbon atom using the model;  "Electrons move in fixed orbits around a nucleus of protons and neutrons."

According to Bohr's model of the atoms, the Rutherford model is basically correct. This implies that Bohr model accepts the idea of a nucleus containing nucleons(protons and neutrons).

In addition, the model also postulates that electrons are found in fixed orbits. These fixed orbits are called energy levels or shells.

Based on the fgiven K_{a} values of the acids, the equilibrim concentrations of[tex]HC_{2}H_{2}O_{2}[/tex] and [tex]NH_{4}^{+}[/tex] is dtermined using ICE tables.

An acid dissociation constant, [tex]K_{a}[/tex] of an acid is a measure of the strength of the acid in solution. The larger the [tex]K_{a}[/tex] value of an acid, the stronger the acid, therefore, acid dissociation constants are usually apply to only weak acids because strong acids have exceedingly large [tex]K_{a}[/tex] values.

It is written as a  qoutient of the equilibrium concentrations of the aqueous species in the acid solution.

For the weak acids such as [tex]HC_{2}H_{2}O_{2}[/tex] and [tex]NH_{4}^{+}[/tex], their equilibrim concentrations are determined using their [tex]K_{a}[/tex] values and an ICE table.

The pH of solutions are estimated using indicators such as methyl orange, methyl red and phenolphthalein. The colors of indicators change according to the pH of the solution

Acidic solutions have pH less than 7 while alkaline solutions have pH greater than 7.

Therefore, acids have low pH and weak acids have low [tex]K_{a}[/tex] values.

Explanation:

On the reactant side, XeO3 is a strong oxidizing agent. It can be a solid or gas. Most likely it is in a solid state.

H+ and Br- combine to form HBr which is a weak acid. So H+ and Br- are in an aqueous state.

On the product side, both Br2 and Xe are not very soluble in water. They will be in gaseous state and H2O is water i.e. liquid state.
