TIMED TEST Two helium isotopes fuse to form beryllium as shown below. The mass of beryllium is 2.73 x 10-7 kg less than the combined mass of the two helium atoms. How much energy was produced during this reaction? The speed of light is 3x108 m/s. Show your work. Use E=mc2.

2.464376e+10 joules of energy were produced during this reaction.

Explanation:

i think

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
