Question

Which type of reaction occurs in the following?

2HgO(s) Right arrow. 2Hg(l) + O2(g)
a decomposition reaction in which a metal is reduced
an acid-base neutralization reaction to produce oxygen gas
a displacement reaction involving two metals
a combustion reaction involving burning a metal in oxygen

Answer 1

decomposition

Step-by-step explanation:

the reactants turn into two different products, thus the reaction is decomposition.

AB -> A + B

Answer 2

A: a decomposition reaction in which a metal is reduced

Step-by-step explanation:

HgO is actually the metal Mercury and in the equation Mercury is being decomposed into the elements Hg and O. (the element for Mercury and Oxygen) So the equation they give you is a decomposition.
