Answer:

Water, 35 liters. Carbon, 20 kilograms. Ammonia, 4 liters. Lime, 1.5 kilograms. Phosphorous, 800 grams. Salt, 250 grams. Saltpeter, 100 grams. Sulfur, 80 grams. Fluorine, seven-point-five. Iron, five. Silicon, three grams. And trace

amounts of 15 other elements.

the ingredients of the average adult,right down to the last specks of protein in your eyelashes. And even though science has given us the entire physical breakdown, there's never been a successful attempt at bringing a human to life. There's still something missing. Something scientists haven't been able to find in centuries of research. ...and in case you're wondering, all those ingredients can be bought on a child's allowance. humans can be made rather cheap. There's no magic to it.

Although coal is a complex mixture of substances, its elemental composition can be approximated by the formula <img src="https:/
Svetllana [295]

Answer:

The correct answer is option b.

Explanation:

2C_{135}H_{96}O_9NS+313O_2\rightarrow 270CO_2+2NO_2+2SO_2+96H_2O

Mass of coal burned = 1.00\times 10^6 metric ton = 1.00\times 10^6\times 10^3 kg=10^9 kg[/tex]

1 metric ton = 10^3kg

Molar mass of coal :

135\times 12g/mol+96\times 1g/mol+9\times 16 g/mol+1\times 14 g/mol+1\times 32 g/mol=1906 g/mol=1.906 kg/mol

1 g = 0.001 kg

Moles of coal ,n :\frac{10^9 kg}{1.906 kg/mol}=5.247\times 10^8 mol

If 2 moles of coal on combustion gives 270 moles of carbon dioxide than n moles of coal will give;

5.247\times 10^8 mol\times \frac{270}{2}=7.083\times 10^{10} mol of carbon dioxide.

Molar mass of carbon dioxide gas = 44 g/mol = 0.044 kg/mol

Mass of 7.083\times 10^{10} mol of carbon dioxide:

7.083\times 10^{10} mol\times 0.044 kg/mol=3.11\times 10^{11} kg
