Question

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

Explanation:

In a double - displacement reaction, the cations and anions of two ionic compounds exchange partners. In the reaction \(MgCl_{2(aq)}+2NaOH_{(aq)}\to2NaCl_{(aq)}+Mg(OH)_{2(s)}\), the \(Mg^{2 +}\) cation from \(MgCl_{2}\) combines with the \(OH^{-}\) anion from \(NaOH\) to form \(Mg(OH)_{2}\), and the \(Na^{+}\) cation from \(NaOH\) combines with the \(Cl^{-}\) anion from \(MgCl_{2}\) to form \(NaCl\).

A single - displacement reaction has the form \(A + BC\to AC + B\). A neutralization reaction is between an acid and a base to form a salt and water. A synthesis reaction has the form \(A + B\to AB\). A decomposition reaction has the form \(AB\to A + B\).

Answer:

double displacement
