Answer:
most likely Energy that's what I'm thinking
Li2CO3 + Ca3(PO4)2 = Li3PO4 + CaCO3
Atoms of the same element, containing the same number of protons, but different numbers of neutrons, are known as isotopes. Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2).
306.0g/22.5mL= 13.6 mL/g
D=m/v
The mass is 306.0
The volume is 13.6
