A nuclear reactor produces an average of 2000MW of thermal energy annually. Compute the number of its fission events per year. Compute the mass of U235 to produce an average of 2000MW of thermal energy for a year. Compare the mass of the nuclear fuel with the equivalent mass of coal. If the nuclear power plant is replaced with a coal-fired power plant burning coal with 75% carbon, calculate the carbon and CO2 emissions per year. Assume Coal TEC

that tool would be a compass

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
