chemical reaction the process by which one or more substances change to produce one or more different substances Stoichiometry The calculation of quantities in chemical reactions QQR method (Quantity, quantity, ratio) is the link between maths and science. The ratio of calculation/measurement = the 1st quantity DIVIDED BY the 2nd quantity. Density mass/volume quantitiative results reported in NUMBERS data can be counted and analyzed by descriptive or inferential statistics Qualititive...

Biology – Enzymes Questions and Answers 100% Correct Define Enzymes Enzyme is a *biological catalyst*, which is *protein* in nature, and can *speed up the rate of a chemical reaction, without it being chemically changed* at the end of the reaction. How do enzymes work? Enzymes work by *lowering the activation energy* of a reaction. Activation energy is the *minimum amount of energy* that reactants must absorb to become activated to start a chemical reaction Properties of an enzyme (7) - Most...

CP Chemistry Exam Review 2024 100% solved A balanced chemical equation allows one to determine the - answermole ratio of any two substances in the reaction. The coefficients in a chemical equation represent the - answerrelative numbers of moles of reactants and products. If one knows the mass and molar mass of reactant A and the molar mass of product D in a chemical reaction, one can determine the mass of product D produced by using the - answermole ratio of D to A from the chemical equa...
