Which quantity can be calculated using the equation E = mc?? O the energy needed to split an atom into separate protons, neutrons, and electrons
O the energy needed to split the nucleus into separate protons and neutrons
O the energy needed to remove an electron from an atom
O the energy needed to add an electron to an atom

what is the question?

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.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
