Catalyst- chemical that increases the rate of a chemical reaction without itself being changed from the reaction. Enzyme- substance produced by a living organism that acts as a catalyst to bring about a particular biochemical reaction. Hope it helps.
Alright yo, I just gave this explanation off earlier
Alright dude, Hess' law isn't as complicated as most people think
Take this example
look for the change in enthalpy of A+B-> AB
A + B -> C enthalpy=10 kJ
C -> AB enthalpy=10 kJ
now if you add everything together you come up with
A + B + C --> AB + C enthalpy= 10kJ + 10 kJ= 20kJ
But notice how C is one the left and on the right of that-- so if it's on the left and on the right of the equation, you could just cancel it out
so you get A+B--> AB
tadaaa!! You found the equation you were looking for
and you know that it's enthalpy is= 10kJ + 10kJ= 20kJ
Hope that helps ya fam!
Just pm me if you need more help!
Answer: the answer is animalia and plantae
Explanation: I just took the test.
Answer:
it requires more energy to lift the book higher because it gains potential enerygy as it goes up.
Explanation:
Answer: The total kinetic energy of all the particles is called the thermal energy or thermal kinetic energy of the object. This is opposed to the kinetic energy of the whole object (like a moving object) and the kinetic energy of a single particle. However, the particles also have their own potential energy.
