CHEMISTRY 1010-EXAM 3
QUESTIONS & CORRECT ANSWERS
NEWEST VERSION
Name the weakest to strongest dipole interactions - Correct Answer ✔✔ induced dipole-
induced dipole, dipole-induced dipole, dipole dipole
Describe the characteristics of an endothermic reaction - Correct Answer ✔✔ 1.
reactions in which there is a net absorption of energy
2. positive sign
3. potential energy of the product is larger than the reactant
Describe the characteristics of an exothermic reaction - Correct Answer ✔✔ 1. reactions
in which there is a net release of energy
2. negative sign
3. potential energy of the reaction is larger than the product
What affects the speed of a reaction? - Correct Answer ✔✔ concentration of reactants
and the temperature of then reactants
Define a Broasted-Lowry acid and base - Correct Answer ✔✔ acid: compound that
donates a proton or H+
base: proton h+ acceptor
Define a Lewis acid and base - Correct Answer ✔✔ acid: compound that accepts a lone
pair of electrons
base: donates a lone pair of elections
what determines the strength of an acid? - Correct Answer ✔✔ strength is determined
by how much of the original chemical is left when dissolved in water.
(when HCl is mixed with water almost all of the original HCl dissociates. compared to
acetic acid when it is mixed with water some of the original acetic acid will remain)
What is activation energy? - Correct Answer ✔✔ the minimum energy required for a
chemical reaction to proceed.
reactant molecules can transform to product molecules only if the reactant molecules
possess an amount go energy equal to or greater than the activation energy. (car
