PLEASE HELP ONLY ONE QUESTION

A chemical reaction occurs when reactant particles collide with proper energy and proper orientation.

Hope this helps! Have a great day! <3

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

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.
