Question

Write a chemical equation for each of the following reactions:Zinc metal reacts with aqueous hydrochloric acid to produce a solution of zinc chloride and hydrogen gas.When solid mercury(II) oxide is heated, liquid mercury and oxygen gas are produced.

Answer 1

Answer:

(a) Zn + HCl gives ZnCl2 + H2

Explanation:

you may balance the equation of you wish to!

Answer 2

Chemical equation for Zinc with HCl and heating of Mercury oxide

Explanation:

When the metal Zinc reacts with aqueous hydrochloric acid, it results in a solution of zinc chloride and hydrogen gas.

Please refer to the attached picture for a balanced equation of this reaction, with correct formatting for subscripts

Zn + 2 HCl --> ZnCl2 + H2

When solid mercury oxide is heated, it results in liquid mercury and oxygen gas.

Please refer to the attached picture for a balanced equation of this reaction.

2HgO --> 2Hg +O2
