This equation represents a synthesis reaction. decomposition reaction. single replacement reaction. double replacement reaction.

Answer 1

The reaction is a double replacement reaction, where cations and anions of two compounds swap to form two new substances.

Step-by-step explanation:

The reaction provided, 2 NaCl (aq) + CuSO4 (aq) → Na2SO4 (aq) + CuCl2 (s), represents a double replacement reaction. In this type of reaction, the cations and anions of two different compounds swap places, forming two new compounds. For example, in this case, sodium (Na+) swaps with copper (Cu2+) to form sodium sulfate (Na2SO4) and copper chloride (CuCl2).

This is different from a synthesis reaction, where two or more substances combine to form a single product; a decomposition reaction, where a single compound breaks down into two or more simpler substances; or a single replacement reaction, where one element replaces another in a compound.

Answer 2
