Use the blood spatter evidence below to determine how many times the victim was hit (find the Points of Convergence only – you do not need to determine Points of Origin). Also, DRAW A SMALL CIRCLE at each location in the room where the victim was hit.

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.
