The Last One Is The Answer: Chemical Reaction Rates Vary With The Conditions Of the Reaction,But Nuclear Decay Rates Do Not.

dezoksy [38]3 years ago

Answer:

Chemical reaction rates vary with the conditions of the reaction, but nuclear decay rates do not.

Explanation:

In chemistry, and more specifically in the area of chemical kinetics, the reaction rate refers to a measure of how quickly a reaction takes place.

The reaction rate may determine the time a product is formed as the reagent is consumed proportionally to the concentration of product formed. This depends on the conditions that are influencing the reaction, so it is important to say that chemical reaction rates vary with reaction conditions.

Radioactive decay occurs when the nucleus of the atom of some chemical element is unstable and then it "breaks", releasing electromagnetic radiation and disintegrating. Important information about nuclear decay is that the rates of this reaction are constant and do not depend on the reaction conditions.

Which of the following is true for a limiting reactant?
lbvjy [14]

Answer:

It is a reactant that produces smaller amount of product.

Explanation:

" The limiting reactant is a reactant that control the amount of product in chemical reaction because of its smaller amount"

Consider the example:

2 H₂ + O₂   →   2H₂O

two moles of hydrogen react with one moles of oxygen and produces two moles of water. when we take two mole of hydrogen and two mole of oxygen than again two mole of water is produced because hydrogen is limiting reactant and one mole of oxygen left un reacted.

Identification of limiting reactant:

Calculate the number of moles of reactant.

compare it with number of moles of product with help of balance chemical equation.

identify the reactant which produces less number of moles of product.

Classify each of the following as a Strong acid (sa) or a Weak acid (wa) and indicate how each should be written in aqueous solu
bazaltina [42]

Answer:

1. wa. Molecular form.

2. wa. Molecular form.

3. sa. Ionic form.

Explanation:

1. hydrocyanic acid

HCN is a weak acid. That means that in the following equilibrium, the molecular form (HCN(aq)) is favored, and that's how it should be written in solution.

HCN(aq) ⇄ H⁺(aq) + CN⁻(aq)

2. hypochlorous acid

HClO is a weak acid. That means that in the following equilibrium, the molecular form (HClO(aq)) is favored, and that's how it should be written in solution.

HClO(aq) ⇄ H⁺(aq) + ClO⁻(aq)

3. hydrochloric acid

HCl is a strong acid. That means that it completely dissociates and it should be written in the ionic form (H⁺(aq) + Cl⁻(aq)) when it is in solution.

HCl(aq) → H⁺(aq) + Cl⁻(aq)
