1 answer:

8 0

Density of nitrogen= 1.20 g/l
no. of grams of nitrogen=m= (1.20g/l)(15.0l)= 18 g
molar mass of nitrogen=M= (14*2)= 28 g/mol

no. of moles of nitrogen=m/M=18/28= 0.643 moles

How does energy in a nuclear reaction get created?

nasty-shy [4]

My answer -

A nuclear reactor produces and controls the release of energy from splitting the atoms of uranium.

Uranium-fuelled nuclear power is a clean and efficient way of boiling water to make steam which drives turbine generators. Except for the reactor itself, a nuclear power station works like most coal or gas-fired power stations.

P.S

Happy to help you have an AWESOME!!! day ^-^
