How long will it take Caroline to travel 45 miles if she is traveling 37mph (miles per hour)?

1) At 45 mph, it takes 2.22... hours to travel 100 miles. Here's how you do this: Divide 100 miles by 45 miles per hour.

Explanation:

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.
