which of the following is the correct word equation for the reaction described below? mercury(ii) oxide breaks down when it is heated to form oxygen gas and liquid mercury. oxygen gas + mercury → mercury(ii) oxide mercury(ii) oxide + oxygen → mercury mercury → mercury(ii) oxide + oxygen mercury(ii) oxide → oxygen + mercury done

which of the following is the correct word equation for the reaction described below? mercury(ii) oxide breaks down when it is heated to form oxygen gas and liquid mercury. oxygen gas + mercury → mercury(ii) oxide mercury(ii) oxide + oxygen → mercury mercury → mercury(ii) oxide + oxygen mercury(ii) oxide → oxygen + mercury done

Answer

Brief Explanations:

The description states mercury(II) oxide breaks down (decomposes) upon heating to form oxygen gas and liquid mercury. In a decomposition reaction, a single reactant breaks into multiple products. So the correct word - equation has mercury(II) oxide as the reactant and oxygen and mercury as the products.

Answer:

D. mercury(II) oxide → oxygen + mercury
