Detailed explanation-1: -1) Make sure the chemical equation is balanced! 2) Determine which reactant is the limiting reagent . 3) Use the limiting reactant to convert from moles of reactants to moles of products. 4) Use the molar mass to convert the moles of product to mass.

Detailed explanation-2: -Mass of products is equal to mass of reactants. This equation can be read in “moles” by placing the word “moles” between each coefficient and formula. A mole-mole factor is a ratio of the moles for any two substances in an equation.

Detailed explanation-3: -Mass-mass calculations involve converting the mass of a reactant to moles of reactant, then using mole ratios to determine moles of product which can then be converted to mass of product.

Detailed explanation-4: -A synthesis reaction occurs when two or more reactants combine to form a single product. This type of reaction is represented by the general equation: A + B → AB. An example of a synthesis reaction is the combination of sodium (Na) and chlorine (Cl) to produce sodium chloride (NaCl).
