Question

question 7 (1 point) the reaction: mgcl2(aq) + 2 naoh(aq) → 2 nacl(aq) + mg(oh)2(s) is an example of what type of reaction? synthesis decomposition neutralization single displacement double displacement question 8 (1 point)

Explanation:

In the reaction MgCl₂(aq) + 2NaOH(aq) → 2NaCl(aq) + Mg(OH)₂(s), the positive - ions (cations) and negative - ions (anions) of the two reactant compounds exchange places. This is characteristic of a double - displacement reaction. A neutralization reaction involves an acid and a base reacting to form a salt and water, which is not the case here. A single - displacement reaction has one element replacing another in a compound. A decomposition reaction has a single compound breaking down into simpler substances, and a synthesis reaction has two or more substances combining to form one compound.

Answer:

double displacement
