Excess reactant - Samenvattingen, Aantekeningen en Examens

Endothermic Absorbs heat, requires hear for the reaction Law of Conservation of Mass Matter is not created nor destroyed in any chemical or physical change, ergo total amount of matter in reactants = total amount of matter in products Mole-mole factors a conversion factor that relates the number of moles of two compounds derived from the coefficients in an equation Limiting reactant the substance that controls the quantity of product that can form in a chemical reaction Excess reactant a rea...

Composition Stoichiometry - calculations involving the mass relationships of elements in compounds Reaction Stoichiometry - calculations involving the mass relationships between reactants and products in a chemical reaction Mole Ratio - a conversion factor that relates the amounts in moles of any two substances involved in a chemical reaction Stoichiometry - (chemistry) the relation between the quantities of substances that take part in a reaction or form a compound (typically a ratio of ...

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 ...

UNIT 4 Combustion of Methane: CH4(g) + 2 02 -> C02 (g) + 2 H20 (g) a) If we have five molecules of CH4 and eight molecules of 02, which is the limiting reactant? 02 is limiting reactant because it yields the least amount of product UNIT 4 N2 (g) + 3 H2 (g) -> 2 NH3 (g) Find mol of NH3 (reactant and excess) H2 is the limiting reactant because it yields 2 molecules of NH3 while N2 yields 6 molecules of NH3 UNIT 4 How many moles of Si3N4 can be made from 1.20 moles of of Si and...

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...

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...
