True or False? Coefficients tell the chemist the proportions of the reactants and products in a chemical?

reaction.True or False? Coefficients tell the chemist the proportions of the reactants and products in a chemical?
very true.





say you have a reaction,


3A+4B -%26gt; 2C





if you start out with 3 moles A, and 3 moles B, B is the limiting reactant, because you are meant to have more moles B than A in the reaction. using the 3 moles, the coefficient of B is 4. the coefficient of C is half that, 2. so, the moles produced of C will be 1.5 moles if B is the limiting reactant in 3 moles.





overall, yes, coefficients definitely determine the proportions of reactants/products present.True or False? Coefficients tell the chemist the proportions of the reactants and products in a chemical?
True true true
