Assume you have 100 g of the compound so you have 87.5 g N and 12.5 H and divide by their molar masses.
87.5 g N / <span>14.0067</span> g (molar mass) = ~6.25 moles
12.5 g H / 1.008 = ~2.4 moles
Empirical Formula = N6H12
Group 7A, it has bromine as a liquid, chlorine and fluorine as gases, and other solids
<h3>Answer:</h3>
1.5 × 10⁸ Kg of CO₂ / Year
<h3>Solution:</h3>
According to statement,
1 kwh generation produces = 0.73 Kg of CO₂
So,
700 kwh generation will produce = X Kg of CO₂
Solving for X,
X = (700 kwh × 0.73 Kg) ÷ 1 kwh
X = 511 Kg of CO₂ / Year
Also, as calculated,
1 household produces = 511 Kg of CO₂ / Year
Then,
300,000 households will produce = X Kg of CO₂ per Year
Solving for X,
X = (300000 households × 511 Kg) ÷ 1 household
X = 153300000 Kg of CO₂ / Year
Or,
X = 1.5 × 10⁸ Kg of CO₂ / Year
