[19] What is the pH at the equivalence point of a weak base – strong acid titration?

[9] For the following reaction, how will the equilibrium shift when going from I → IV?  2 NaHCO3 (s)  ↔  Na2CO3 (s)  +  H2O (g)  +  CO2 (g) I.  remove CO2            II.         add Na2CO3 III.  add NaHCO3    IV.        increase the temperature

[14] What is the pH of a solution containing 0.40 M H3CCO2H and 0.20 M sodium acetate? Kb(NaO2CCH3) = 5.56 × 10-10.

[3] The gas-phase reaction of A and BC, is second order in A and first order in BC. What is the rate law, and what are the units of the rate constant? A2 (g)  +  2 BC (g)  →  2 AB (g)  +  C2 (g)

A training program increases workers’ wages, but it also benefits local employers by improving the overall skill level of the regional labor force.On agraph, the socially efficient quantity of training occurs where:

A chemical producer’s marginal social cost (MSC) lies above marginal private cost (MPC). The market outcome results in:

The Environmental Protection Agency requires coal-fired utilities to reduce sulfur emissions by 25% over the next five years and imposes penalties for noncompliance. This policy is best classified as:

A local government funds mosquito control because the benefits extend across entire neighborhoods. It would be difficult to exclude individual households from reduced mosquito exposure once spraying occurs. The strongest reason private markets may underprovide mosquito control is:

A chemical manufacturer bases production decisions only on private production costs and ignores wastewater cleanup costs imposed on downstream communities. Without government intervention, economists would predict the firm will:

A public radio station broadcasts emergency alerts, local news, and educational programming. Many listeners benefit without donating, even though donations are needed to support operations. This funding challenge exists mainly because public radio is often:
