Answer:
thermochemical equation
Explanation:
A(n)__thermochemical equation_____is a balanced chemical equation that includes the physical states of all reactants and products, and the energy change that accompanies the reaction.
Answer:
low pH
Explanation:
Since pH = -log [H+], a high [H+] would mean that the pH is low.
The car stopped due to a gravitational pull (gravity slowing it down) the energy is converted to kinetic energy and heat energy.
Polar Covalent Bond
This bond exists when atoms that have different electronegativities share electrons in a covalent bond, the electrons are not transferred from one atom to the other as in the case of ionic bond.
It is 2 KJ
It is because the formula is :
q=m∆Hf
where m is the mass and ∆Hf is the heat fusion.
So, we get:
q=80×25
q=2000J or 2 KJ
