What is the ph after 0.195 mol of naoh is added to the buffer from part a? assume no volume change on the addition of the base.
part a: what is the ph of a buffer prepared by adding 0.809 mol of the weak acid ha to 0.609 mol of naain 2.00 l of solution? the dissociation constant ka of ha is 5.66×10−7

The following questions a24 - a26 relate to 100 ml of 0.0150 m solution of benzoic acid (c6h3cooh). ka(c6h3cooh) = 6.4 x 10^-5. what is the ph of the solution after the addition of 1 x 10^-3 moles of naoh? you may assume no volume change to the solution upon addition of the naoh.

The equation below shows a chemical reaction. a + b + heat —> c + d according to the law of conservation of energy, which statement is true? a. the reactants absorb heat because they have less energy than the products. b. the products release heat because they have more energy than the reactants. c. the reactants generate heat because they have more energy than the products. d. the products require heat to form because they have less energy than the reactants.
