Calculate the pH of each solution. A solution containing 0.0215 M maleic acid and 0.0290 M disodium maleate. The a values for maleic acid are 1.20×10−2 (a1) and 5.37×10−7 (a2).
pH=

A solution containing 0.0300 M succinic acid and 0.017 M potassium hydrogen succinate. The a values for succinic acid are 6.21×10−5 (a1) and 2.31×10−6 (a2).
pH=

Thank you for the help! I know i have to use the Ka values and the HH equation but it always comes out wrong for me :/

If you have 5.25 grams of methane (ch4), how many grams of co2 will you produce ?

The human activities in two locations are described below: location a: rampant use of plastic containers location b: excessive use of pesticides and fertilizers which statement is most likely true? location a will have poor air quality because plastic is biodegradable. location a will experience water scarcity because plastic absorbs moisture. the population of honeybees will increase in location b because production of crops will increase. the population of fish in location b will decrease because the water is contaminated.

Malik formed a hypothesis that an increase in atmospheric oxygen levels by 10% would cause red-legged grasshoppers to grow larger than normal. suppose that malik performs an experiment to test his hypothesis. which of these actions would represent a scientific mistake in his experiment? a. he experiments on live grasshoppers instead of preserved ones. b. he focuses on red-legged grasshoppers instead of all kinds of grasshoppers. c. he varies the nitrogen and carbon dioxide levels in the air from one trial to the next. d. he conducts the experiment in a controlled lab setting with a lab partner. e. he measures the mass and length of his specimens at the start of each trial.
