The recipe makes 24 Treats.Write something like a balanced chemical equation for this problem.If I have 2.2 Tablespoons of butter, 3.5 cups of marshmallows and 3.5 cups of Rice Krispies, what is the limiting reactant?Then, how many Treats can I make?One industrial process for producing nitric acid begins with the following reaction:NH3 + O2 → NO + H2OBalance the equationIf 2.90 moles of NH3 and 3.75 moles of O2 are combined, what is the limiting reactant?How much NO would be produced?How many moles of the excess reactant are left over? Copper is changed to copper (II) nitrate by nitric acid according to the following equation:HNO3 + Cu → Cu(NO3)2 + NO2 + H2OBalance the equationIf 3 moles of HNO3 and 2.5 moles of Cu are combined, what is the limiting reactant?How much Cu(NO3)2 would be produced?How many moles of the excess reactant are left over? N2H4 + H2O2 → N2 + H2OBalance the equation.If .750 moles of N2H4 is reacted with 4.75 moles of H2O2, what is the limiting reactant?If 52.0 g of N2H4 are reacted with 47.0 g of H2O2, what is the limiting reactant?How many grams of H2O can be produced?If the percent yield in lab is calculated to be 78.9% what is the actual yield?Na2SO3 + HCl NaCl + SO2 + H2OBalance the equation.What is the limiting reactant if 0.250 moles of HCl is reacted with 0.125 moles of Na2SO3?If 25.0 g of Na2SO3 are reacted with 22.0 g of HCl, what is the limiting reactant?How many grams of SO2 can be produced?If 4.73 g of SO2 are produced in the lab, what is the percent yield?Calculate the empirical formula of 2.3 g of sodium combined with 0.80 g of oxygenCalculate the empirical formula of carbon 75% and hydrogen 25%Calculate the empirical formula of carbon 85.7% and hydrogen 14.3%Calculate the empirical formula of 20% magnesium, 26.6 % sulfur, 53.3 % oxygenThe empirical formula of butane is C2H5, and it molecular mass is 58g.
