Water with high levels of calcium ions is referred to as hard water. While hard water has health benefits, this type of water has economic implications in the industry and households too. In the industry, hard water can cause a breakdown of equipment such as boilers, over time. In the household, too much soap is used when washing with hard water than soft water. Therefore hard water requires to be softened before industrial use. Economically, this increases the cost of production.
During a chemical reaction, the stuff that reacts together are the reactants. The stuff that is made during the reaction are the products. A catalyst is something that can be added to the reaction that allows it to react faster, but does not get used up during the reaction.
Answer:
1 mol Al. 26.9815 g Al. ×. 2 mol AlCl. 3. 2 mol Al. =0.100 mol AlCl3. The balanced equation says: 3 mol Cl2 produces ... that the initial mass of Al was larger than required to react with all of the Cl2. The sum of the masses.
