A 155g sample of an unknown substance absorbs 58970 J of heat as the temperature is increased from 25ᵒC to 40ᵒC. What is the specific heat of the substance? help with 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.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

i wish i could but this one is weird give me abc and i can solve it.
