Explanation:
during the industrial revolution americans were switching from rural to urban life, thus using up more fossil fuels, and working in factories
In our Solar System earth is the only planet to have life forms such as plants, animals and humans. We are also the only planet to have drinkable water on it. If you want to talk more about the atmosphere, we are the only planet to have an ozone layer or anything to trap heat and and protect from the harmful rays of the sun.
Answer:
D) 174 g/mol
Explanation:
Step 1: Given and required data
- Density of the gas (ρ): 7.10 g/L
- Ideal gas constant (R): 0.0821 atm.L/mol.K
Step 2: Convert "T" to Kelvin
We will use the following expression.
K = °C + 273.15
K = 25.0°C + 273.15
K = 298.2 K
Step 3: Calculate the molecular weight (M) of the gas
We will use the following expression derived from the ideal gas equation.
ρ = P × M / R × T
M = ρ × R × T / P
M = 7.10 g/L × (0.0821 atm.L/mol.K) × 298.2 K / 1.00 atm
M = 174 g/mol
There are two H2 .There are four nitrogen atoms present. There are two NH3 formed
