consider the incomplete reaction below. naoh + x → nach3coo + h2o what is x in this reaction? o nh4oh o…

Explanation:

Step1: Analyze the reaction type

This is an acid - base neutralization reaction. Sodium hydroxide (NaOH) is a base. In an acid - base neutralization reaction, a base reacts with an acid to form a salt and water.

Step2: Determine the acid based on the salt formed

The salt formed is sodium acetate ($NaCH_3COO$). The acetate ion ($CH_3COO^-$) comes from the acid. The acid corresponding to the acetate ion is acetic acid ($CH_3COOH$). When $CH_3COOH$ reacts with $NaOH$, the hydrogen from the acid combines with the hydroxide from the base to form water, and the sodium ion from the base combines with the acetate ion from the acid to form sodium acetate. The reaction is $NaOH + CH_3COOH\rightarrow NaCH_3COO + H_2O$.

Answer:

D. $CH_3COOH$
