A number in front of a chemical formula in an equation that indicates how many molecules or atoms of each reactant and product are involved in a reaction?

Answer 1

This number tells a surprising amount about the chemical reaction. For starters, they are placed there so that there is an equal number of each element on either side of the equation. They also tell you the number of moles of each substance used in the reaction. The amount of a substance that contains as many atoms, molecules, ions, or other elementary units as the number of atoms in 0.012 kilogram of carbon 12. The number is 6.0225 × 1023, or Avogadro's number. Also called gram molecule). Ideally, you would want to use that many moles of each substance to get a complete reaction. This is not often practical, so it is used as a ratio, which is also helpful in determining the limiting reactant and other numerical values. Unfortunately, I'm not a very good teacher and there is a lot more to it than there first appears, but I hope this is at least a satisfactory explanation.

In a chemical equation, numbers often appear in front of a chemical formula. These numbers tell you the number of molecules or atoms of each substance in the reaction.
