Determine the acid-ionization constant of methanoic acid in a solution containing 0.345 M methanoic acid and a pH of 2.80 at 25oC. Methanoic acid is a weak monoprotic acid, with the formula HCO2H at 25oC.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

the correct answer is:

a. formation of precipitation
