Acetic acid has a Ka of 1.75x10^-5. The weak acid approximation (for this class) would be allowed for which of the following initial concentrations of acetic acid? a. 1.75E^-6
b. 1.75E^-5
c. 0.00175
d. 0.0175
e. 0.175

e. 0.175

Explanation:

The equilibrium constant of a reaction is the value of its reaction quotient when at equilibrium. The equilibrium concentration of a product or reactant depends on the initial concentrations and equilibrium constant of the reactants and products.

The weak acid approximation depends on the initial concentration and equilibrium constant (). The farther the initial concentration and equilibrium constant are from one another, the more likely the approximation would be valid.

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
