Directions You must solve each of the following problems using dimensional analysis. The equation can be separated as H + O = H2O and H + O = HO, each of which does have a unique solution. Thus 2 mol of H2 react with 1 mol of O2 to produce 2 mol of H2O. It is important to remember that some species are present in excess by virtue of the reaction conditions. The worksheet has ten problems that give a balanced reaction and a starting amount of a reactant or product in, determine the mass of another reactant or product in each problem. Determining the stoichiometry of chemical reactions aids you to understand the chemistry of any reaction by comparing the amount of all entities present in it. Note the moles of BaCl2 are on the bottom. Pre-made digital activities. << 200 grams to liter = 0.2 liter. General Guidelines for solving: 1. balance equation. Metal-organic frameworks (MOFs) are highly nanostructured coordination polymers that contain metal cations and organic linkers and feature very large pore volumes and surface areas.
