Firstly the limiting reactant should be identified. Limiting reactant is the reactant that is in limited supply, the amount of product formed depends on the moles present of the limiting reactant.
the stoichiometry of x to y = 1:2 1 mole of x reacts with 2 moles of y if x is the limiting reactant, there are 3 moles of x, then 6 moles of y should react, however there are only 4 moles of y. Therefore y is the limiting reactant and x is in excess. 4 moles of y reacts with 2 moles of x since there are 3 moles of x initially and only 2 moles are used up, excess amount of x is 1 mol thats in excess.
Sodium chloride is a nonreactive solid at room temperature, and is commonly known as table salt. The two elements that make up sodium chloride are sodium and chlorine. Sodium is a very reactive metal that tastes bad. Pure sodium is explosive when it comes in contact with water. Hope this helps
acquired traits are traits that organisms develops over a lifetime. adaptation are trait that enhances an organism's ability to survive and reproduce in its environment.
