Answer:

False

Explanation:

It is coal-fired power plants that produce mercury, air pollution, and carbon dioxide.

However, nuclear energy produces radioactive waste that must be stored for many years before it can be safely disposed.

Combustion of hydrocarbons such as methane (CH) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earths atmo

Sveta_85 [38]

Answer:

The balanced chemical reaction of combustion of methane is:

$CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)$

734 liters of carbon dioxide gas is produced. .

Explanation:

The balanced chemical reaction of combustion of methane is:

$CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)$

Mass of methane gas = 0.500 kg = 500 g (1 kg= 1000 g)

Moles of methane = $\frac{500 g}{16 g/mol}=31.25 mol$

According to reaction, 1 mole of methane gas gives 1 mole of carbon dioxide gas. Then 31.25 moles of methane will give :

$\frac{1}{1}\times 31.25 mol=31.25 mol$ of carbon dioxide

Using ideal gas equation:

PV = nRT

where,

P = Pressure of gas = $\1 atm$

V = Volume of gas =?

n = number of moles of carbon dioxide gas = 31.25 mol

R = Gas constant = 0.0821 L.atm/mol.K

T = Temperature of gas =13.0°C=13.0+273.15 K= 286.15 K

Putting values in above equation, we get:

$V=\frac{31.25\times 0.0821 atm L/mol K\times 286.15 K}{1 atm}$

V = 734.15 L ≈ 734 L

734 liters of carbon dioxide gas is produced. .
