1) How many moles of hydrogen gas can be produced if 0.57 moles of hydrochloric
acid, HCl, reacts with excess solid zinc according to the following chemical
equation?
2 HCl + Zn → Hz + ZnCl2

Answers

Answer 1

Answer: 0.28 mol H2

Explanation:

0.57mol HCl         1mol H2          

                             2mol Hcl

Answer 2

Hydrochloric acid and zinc show the displacement reaction to produce hydrogen gas and zinc chloride. 0.57 moles of hydrochloric acid and excess zinc react to produce 0.28 mol H₂.

What is a displacement reaction?

A displacement reaction is the removal of one of the elements from the reactant with highly active species of the reactivity species to produce the products. It can be a single or double displacement reaction.

The balanced chemical displacement reaction is given as:

2 HCl + Zn → H₂ + ZnCl₂

Here, two hydrochloric acids react with zinc to form one mole of hydrogen gas and one mole of zinc chloride.

Given,

Hydrochloric acid = 0.57 moles

Using proportions to calculate moles as:

If 2 moles of HCl = 1 mole H₂

Then, 0.57 moles = X moles

X = 0.57 ÷ 2

= 0.28 mol H₂

Therefore, 0.57 mole HCl produces 0.28 moles of hydrogen gas.

How can one tell if a reaction is a redox reaction?
O A. Elements change phases.
O B. A precipitate is formed.
O C. Spectator ions are present.
O D. Electrons are gained and lost.

Answers

Answer:

D. Electrons are gained and lost

Explanation:

When electrons are gain and lost, redox reaction takes place. In redox reaction, reduction and oxidation tales place simultaneously. Therefore, option D is correct.

What is redox reaction ?

Redox reactions include a change in the oxidation state of the substrate. When electrons are lost or the oxidation state increases, it is called oxidation; when they are gained or the oxidation state decreases, it is called reduction.

Redox reactions are those in which there is a change in the oxidation number, with both an increase and a drop in number. The reaction called non-redox if this does not take place.

Oxidation and reduction always occur jointly because any loss of electrons by one substance must be followed by a gain of electrons by another. Therefore, oxidation-reduction processes or simply redox reactions are other names for electron-transfer events.

Thus, option D is correct.
