Question

acetamide ($\text{ch}_3\text{conh}_2$) is used in the leather-making process as a softener. acetamide and water ($\text{h}_2\text{o}$) are produced when acetic acid ($\text{ch}_3\text{cooh}$) and ammonia ($\text{nh}_3$) react. this chemical reaction is represented by the model below.determine the number of each type of atom in the reactants and products.| | h | c | n | o || ---- | ---- | ---- | ---- | ---- || number of atoms in reactants | $square$ | 2 | 1 | $square$ || number of atoms in products | $square$ | 2 | 1 | $square$ |(atom key: h=light gray, c=dark gray, n=blue, o=red)

Explanation:

Step1: Count H in reactants

Reactants: $\text{CH}_3\text{COOH}$ has 4 H, $\text{NH}_3$ has 3 H. Total: $4 + 3 = 7$

Step2: Count O in reactants

$\text{CH}_3\text{COOH}$ has 2 O, $\text{NH}_3$ has 0 O. Total: $2 + 0 = 2$

Step3: Count H in products

Products: $\text{CH}_3\text{CONH}_2$ has 5 H, $\text{H}_2\text{O}$ has 2 H. Total: $5 + 2 = 7$

Step4: Count O in products

$\text{CH}_3\text{CONH}_2$ has 1 O, $\text{H}_2\text{O}$ has 1 O. Total: $1 + 1 = 2$

Answer:

	H	C	N	O
Number of atoms in products	7	2	1	2
