Coal has an energy content of approximately 2.4 x 107 j/kg, and about 4% sulfur content by mass. if coal-fired power plants in the united states produce around 2.6 x 1011 watts of electricity, how many kilograms of sulfur will be emitted from coal plants in two weeks? note that 1 j = 1 w·sec.

kilograms of sulfur will be emitted from coal plants in two weeks

Explanation:

Power produced by power plants in the United States :P

P=

1 Joule = Watts × Seconds

Watts = Joule/Second

P=

This means that Joules of enrgy is produced in one second.

So, energy produced in 2 week:

1 week = 7 days

1 day  =  24 hours

1 hour = 3600 seconds

2 week = 2 × 7 × 24 × 3600 s=1,209,600 s

Energy produced in 1,209,600 s: E

Coal has an energy content =

Mass of coal used while producing E amount of energy: m

Percentage of sulfur in coal = 4% by mass

Mass of sulfur produced from in 2 weeks:

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
