Hydrazine (N2H4) emits a large quantity of energy when it reacts with oxygen, which has
led to its use as a fuel for rockets,
N2H4(ℓ) + O2(g) → N2(g) + 2 H2O(g).
How many moles of water are produced
when 22 g of pure hydrazine is ignited in the
presence of 87 g of pure oxygen?
Answer in units of mol.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
