If you start with 62.5 grams of CaCO3, how many grams of ZnCO3 will be produced? Identify the mole ratio
3 CaCO3 + Zn3(PO4)2 → Ca3(PO4)2 + 3 ZnCO3

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

he would use the colour black

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
