Question

ammonia, nh₃, is a common chemical compound used in cleaning products and fertilizers. which statement describes the atoms present in three molecules of ammonia? three molecules of ammonia would contain 1 atom of nitrogen and 3 atoms of hydrogen. three molecules of ammonia would contain 3 atoms of nitrogen and 1 atom of hydrogen. three molecules of ammonia would contain 3 atoms of neon and 9 atoms of hydrogen. three molecules of ammonia would contain 3 atoms of nitrogen and 9 atoms of hydrogen.

Explanation:

Step1: Analyze one ammonia molecule

One molecule of \(NH_3\) (ammonia) has 1 atom of nitrogen (N) and 3 atoms of hydrogen (H).

Step2: Calculate for three molecules

For three molecules of \(NH_3\), the number of nitrogen atoms is \(3\times1 = 3\) (since each molecule has 1 N atom), and the number of hydrogen atoms is \(3\times3=9\) (since each molecule has 3 H atoms). So three molecules of ammonia would contain 3 atoms of nitrogen and 9 atoms of hydrogen.

Answer:

The correct statement is "Three molecules of ammonia would contain 3 atoms of nitrogen and 9 atoms of hydrogen" (the last option among the given choices).
