In one recent year, electric power plants in the United St$?$ates consumed about $1\mathrm{.}14{10}^{11}kg8?$

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.

Convert your answer to scientific notation. For this part A$,$ enter only the decimal number. As an example, for $3\mathrm{.}23x$

${10}^4,$ enter just $3\mathrm{.}23$ Part $2$ How many total significant figures should you answer in part A be rounded to
