Question

In a chemical reaction, the difference between the potential energy of the products of the potential energy of the reactants is equal to the
a)activation energy
b)entropy of the system
c)heat of fusion
d)activation energy

Answer 1

a) and d) are the same!
None of the 3 answers is correct.

Answer 2

The difference between the potential energy of the products of the potential energy of the reactants is called the enthalpy of the reaction.

Answer 3

sorry the choices were
a)activation energy
b)entropy of the system
c)heat of fusion
d)heat of reaction

Answer 4

What Mani_Jha said (enthalpy of reaction) is another terminolgy for "heat of reaction". When you study more advanced chemistry, you might reconsider this answer, using Gibbs free energy instead.

Answer 5

so the answer is heat of reaction too right?

Answer 6

right!

Answer 7

tyyy

Answer 8

hey could you help me with some questions i dont get few of them

Answer 9

According to reference table U, which of these compounds is most stable?
ethane
ethyne
aluminum oxide
or carbon dioxide

Answer 10

I do not know this reference table you are mentioning (not in use in my country probably).
Anyway, the most stable compound is always the one for which you need most energy to rip it apart, more precisely to bring it back to the elements it is made of.
Sorry I am not able to help you more than that.

Answer 11

Probably the aluminum oxide since it is an ionic compound.
