$2-85$ When a hydrocarbon fuel is burned, almost all of the cas bon in the fuel burns completely to form $C{O}_2($carbon dionule which is the principal gas causing the greenhouse effoct and then global climate change. On average, $0\mathrm{.}59kg$ of $C{O}_2$ is produced for each $kWh$ of electricity generated from a power plant ther about $700kWh$ of electricity per year. Determine the amoun of $C{O}_2$ production that is due to the refrigerators in a city with $300,000$ households.

$2-86$ Repeat Pros. $2-85,$ assuming the electricity is prodbcod by a power plant that burns coal. The average production of $C{O}_2$ in this case is $1\mathrm{.}1kg$ per $kWh.2-86$ please
