Answer: Well!
Explanation: I was going to answer D but fverdell82156 got to it first! So I have to agree with him! It is D!
One molecule of ammonia is composed of two atoms of nitrogen and three atoms of hydrogen. Option B.
<h3>What is an equation?</h3>
The term chemical equation has to do with the presentation of a chemical reaction on paper in a way that it can be easily understood. It is easy to write an equation to show what is going on in a reaction system.
Now we have the reactions as shown in the question. In this reaction which is the synthesis of ammonia and occurs industrially in the Haber process. The statement that is not true is that; one molecule of ammonia is composed of two atoms of nitrogen and three atoms of hydrogen. Option B.

Time taken = 3 hours
<h3>Further explanation</h3>
Given
speed : 75 mph
distance : 225 miles
Required
time taken
Solution
An equation of constant velocity motion
d = distance = m
v = speed = m / s
t = time = seconds
Input the value :
t = d : v
t = 225 miles : 75 miles/hour
t = 3 hours
Answer:
V = 48.64 L
Explanation:
Given data:
Mass of CO₂ = 85.63 g
Temperature = 273 K
Pressure = 1 atm
Volume of CO₂ = ?
Solution:
Number of moles of CO₂:
Number of moles = mass/molar mass
Number of moles = 85.63 g / 40 g/mol
Number of moles = 2.14 mol
Volume in Litter:
PV = nRT
R = general gas constant = 0.0821 atm.L/mol.K
1 atm× V = 2.14 mol ×0.0821 atm.L/mol.K ×273 K
V = 48.64 atm.L / 1 atm
V = 48.64 L
