given equation Mg + 2 HCl —> MgCl2 + H2 If a chemist uses 20g Mg and excess HCl, what mass of MgCl2 product would form?
Mg + 2 HCl -> MgCl2 + H2. If a chemist uses 20 g Mg and 20 g HCl, what is the limiting reactant? What mass of the excess reactant is leftover when the reaction is complete?
Limiting Reactants, Excess Reactant, and % Yield Name H2+Cl2HCI A gaseous mixture containing 7.5 g of H; gas and 9.00 g of Cl2 gas react to form hydrogen chloride gas. а) Which is the limiting reactant? If all the limiting reactant is consumed, how many grams of HCl are produced? How many grams of excess reactant remain un-reacted? b) c) Cl2+3F22CIF Chlorine reacts with fluorine to form gaseous chlorine trifluoride. You start with 50.0g of chlorine and 95.0g of fluorine....
1. Hydrochloric acid can dissolve solid magnesium according to the reaection below. What minimum magnesium in grams can be dissolved by 8.52 g of HCI? (3 pts) Mg(s) + 2 HCl(aq) + MgCl2(aq) + H2(g) 2. Consider the reaction between NiS2 and O2 below. If 24.3 g of NiS2 reacts with 22.6 g of O2, what is the limiting reactant and theoretical yield of NiO? (5 pts) 2 NiSz(s) + 5 O2(g) 2 NiO(s) + 4 SO2(g) 3. The equation...
an experiment only formed 14 g of product (actual yield), thus the percent yield of product for that experiment is 1.4/2.0x100 - 70% % yield actual yield theoretical Wald X 100 You can rearrange this equation to calculate the actual yield if given the % and theoretical yields, or the theoretical yield if given the % and actual yields. Let's Practice: 1. Answer the following questions based on the reaction below (5pts) 2 NaCl + Mg0 Na2O + MgCl2 What...
