In one recent year, electric power plants in the United States consumed about $1\mathrm{.}14{10}^{11}kg{?}^{6}E$

natural gas, $C{H}_4.$ Natural gas burns according to the following equation:

$C{H}_4(g)+2O_2(g)2H_{2}O(g)+C{O}_2(g)$

How many kilograms of $C{O}_2$ were released into the atmosphere from these power plants

during that year? Use a periodic table.
