Balance the following equation by inserting coefficients as needed. Balance the following equations by inserting coefficients as needed. Write the balanced chemical equation for the reaction shown here. Do not subscript the arrow. In a chemical reaction, exactly 2 mol of substance A react to produce exactly 3 mol of substance B. 2 A rightarrow 3B How many molecules of substance B are produced when 26.8 g of substance A reacts? The molar mass of substance A is 16.7 g/mol. Convert the mass of A to moles. Convert the number of moles of A to the number of moles of B. Convert the number of moles of B to molecules of B. When heated, KCIO3 decomposes into KCI and O2. 2KCIO3 rightarrow 2KCl+ 3O2 If this reaction produced 50.6 g of KCI, how much O2 was produced (in grams)? When calcium carbonate is added to hydrochloric acid, calcium chloride, carbon dioxide, and water are produced. CaCO3(s) + 2HCl(aq) rightarrow CaCI2(aq) + H2O(l) + CO2(g) How many grams of calcium chloride will be produced when 28.0 g of calcium carbonate are combined with 14.0 g of hydrochloric acid? Which reactant is in excess and how many grams of this reactant will remain after the reaction is complete? of Combining 0.254 mol of Fe2O3 with excess carbon produced 12.8 g of Fe. Fe2O3 + 3C rightarrow 2Fe + 3CO What is the actual yield of iron in moles? What was the theoretical yield of iron in moles? What was the percent yield? Assuming an efficiency of 30.60%, calculate the actual yield of magnesium nitrate formed from 140.2 g of magnesium and excess copper(II) nitrate. Mg + Cu (NO3)2 rightarrow Mg(NO3)2 + Cu
