Shari is wanting to create a solution. Which of these could Shari do to accomplish her goal? A. Run electrical current through a metal. B. Use evaporation to separate a solvent from a solute.
C. React two elements together to form ions.
E. Pour a solute into a solvent.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

i think its 100

i hope this !
