which type of reaction occurs in the following? 2hgo(s) → 2hg(l) + o₂(g)\n a decomposition reaction in which a metal is reduced\n an acid - base neutralization reaction to produce oxygen gas\n a displacement reaction involving two metals\n a combustion reaction involving burning a metal in oxygen

Answer

Brief Explanations:

A decomposition reaction breaks a compound into simpler substances. Here, mercury - oxide (HgO) breaks down into mercury (Hg) and oxygen (O₂). There is no acid - base neutralization as no acid or base is involved. It's not a displacement reaction as no element displaces another in a compound. Also, it's not a combustion reaction as combustion involves a substance reacting with oxygen to release heat and light, and here HgO is breaking down, not burning in oxygen.

Answer:

a decomposition reaction in which a metal is reduced
