the cations of strong bases have what affect on pH(if placed in their own solution?no affect; do not react with water the cations that are conjugate acids of weak bases have what affect on pH (if placed in their own solution)?lowers the pH of the solution the cations that are small and highly charged metals have what affect on pH?lowers the pH of a solution the anions of strong acids (when placed in their own solution) have what affect on pH?no affect; do not react in water.

The first law of thermodynamics can be given as - DeltaE = q+w A reaction that is spontaneous as written - will proceed without outside intervention Of the following (S, H, q, E, T), only ___ is NOT a state function. - q When a system is at equilibrium - the process is not spontaneous in either direction A reversible process is one that - an be reversed with no net change in either system or surroundings.

Chemical kinetics - the study of how fast a chemical reaction proceeds from reactant(s) to product(s) and the mechanism by which the reaction occurs Reaction rate - change in concentration of reactant(s) or product(s) per unit of time Most reactions don't go a ______ speed and will __________ as reactants ________ - steady; slow down; decrease rate law - expression that shows how rate depends on concentration of reactants 1st order - k units - 1/m s

When a liquid is heated at its boiling point the, - Temperature of the liquid remains the same as long as any liquid is present The normal boiling point occurs when the - Vapor pressure of the liquid equals the external pressure Which of the following compounds forms a covalent network solid? - C (diamond) Which type of bonding does Mg form upon solidification? - Metallic Solids having no ordered long-range structure are classified as - Amorphous The Clausius-Clapeyron Equation can be use...

Which of the following statements about chemical reaction rates is false? - The Activation energy, Ea, will always be greater than the change in enthalpy, (change in H) Which of the following statements about chemical reaction rates is true? - -Most reactions proceed faster if the concentration of one or more of the reactants is increased -Sometimes changing the concentration of a reactant has no effect on the reaction rate for a net chemical reaction. -The physical state of reactants is a...
