consider the incomplete reaction below.\nnaoh + x → nach3coo + h2o\nwhat is x in this reaction?\no nh4oh\no…

Explanation:

Step1: Analyze the reaction type

This is an acid - base neutralization reaction. NaOH is a base.

Step2: Determine the product components

The product is sodium acetate ($NaCH_3COO$) and water ($H_2O$). In an acid - base reaction, the salt is formed from the cation of the base and the anion of the acid. Here, the anion in the salt is $CH_3COO^-$.

Step3: Identify the acid

The acid that provides the $CH_3COO^-$ anion is acetic acid ($CH_3COOH$). When $CH_3COOH$ reacts with $NaOH$, it forms $NaCH_3COO$ and $H_2O$ according to the reaction: $NaOH + CH_3COOH\rightarrow NaCH_3COO + H_2O$.

Answer:

D. $CH_3COOH$
