When 4 moles of aluminum are allowed to react with an excess of chlorine gas, Cl2, how many moles of aluminum chloride are produced? 2Al + 3Cl2 → 2AlCl3 A) 1 mole B) 2 moles C) 3 moles D) 4 moles E) 5 moles
In stoichiometric calculations, this is usually the known amount (in grams or moles) of at least one reactant or product. To convert between moles and grams, multiply moles by the molar mass to get grams, or divide grams by the molar mass to get moles.
Aluminum reacts with chlorine gas to form aluminum chloride via the following reaction: 2Al(s)+3Cl2(g)→2AlCl3(s) You are given 23.0 g of aluminum and 28.0 g of chlorine gas. If you had excess chlorine, how many moles of of aluminum chloride could be produced from 23.0 g of aluminum?
You’ll need a grams to moles formula to find the moles of a substance you have. For example, once you have carried out a reaction, you will weigh your product to find out how many grams have been produced. You can then convert grams back to moles to check the yield of the reaction. Grams to Moles Formula
In the following equation how many moles of aluminum chloride are produced from 2.50 mol of hydrochloric acid? 2 Al (s) + 6 HCl(aq) → 2 AlCl 3 (aq) + 3 H 2 (g)
12 kwi 2018 · Explanation: This is an example of a limiting reactant problem. The first step is to write down the balanced chemical equation. That is, 2Al(s) +3Cl2(g) → 2AlCl3(s) We got seven moles of aluminium and eight moles of chlorine. So, we find the limiting reactant.
