Answer: The formula mass (formula weight) of a molecule is the sum of the atomic weights of the atoms in its empirical formula. The molecular mass (molecular weight) of a molecule is its average mass as calculated by adding together the atomic weights of the atoms in the molecular formula.
Hope this helps.... Stay safe and have a great weekend!!!!! :D
Effects of changes in volume in a reversible reaction in a chemical equilibrium can be predicted using Le Chatelier's Principle. I think this might be the answer, I hope it helps.
Answer:
Potential energy
Explanation:
A mountain climber at the peak of a mountain has potential energy.
The potential energy of a body is stored energy in a body. It is function of mass and position of the body.
Mathematically;
P.E = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Answer:
1) Reaction
