Chapter 3—Chemical Equations and Reaction Stoichiometry MULTIPLE CHOICE 1. Which of the following is not a consequence of the Law of Conservation of Matter? a. It provides a basis for balancing chemical equations. b. It means that there will be no observable change in the quantity of matter during a chemical reaction. c. As a result, there will be the same number of moles on both the reactant and the product side of a balanced equation. d. It can be stated as "matter is neither creat...

Stoichiometry - Part of chemistry that studies amount of substances that are involved in reactions Mole Ratio - Identify how many moles of product are formed from a certain amount of reactant. Molar mass - Defined as the mass of given substance divided by its amount of substance Limiting Reaction - How much of the product is produce Excess Reaction - what is left over Theoretical yield - Quantify of a product obtained from the complete conversion of the limiting reactant in chemical reacti...

stoichiometry - the calculations of quantities in a chemical reaction mole ratio - a conversion factor derived from the coefficients of a balanced chemical equation interpreted in terms of moles mass-mass calculations - a stoichiometric computation in which the mass of products is determined from the given mass of reactants mole - quantity of matter that contains 6.02 x 10^23 particles of that substance reactant - A chemical substance that is present at the start of a chemical reaction ...

Subscript - A number in a chemical formula that tells the number of atoms in a molecule or the ratio of elements in a compound Law of conservation of mass - mass is neither created nor destroyed during ordinary chemical reactions or physical changes Mole ratio - fraction formed from the coefficients in a balanced chemical equation. Avogadro's Number - number of representative particles in a mole, 6.02 X 10^23 Products - The elements or compounds produced by a chemical reaction. On the rig...
