Emeka carried out a reaction in which a gas was given off. He followed the progress of the reaction by measuring the mass of the reaction vessel over time. After 5 minutes the mass of the reaction vessel had decreased from 120g to 114.5g. Calculate the rate of this reaction.

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.
