Calculate the theoretical amount of 3 M sodium hydroxide needed to convert the benzoic acid (half the weight of the sample) to its water - soluble salt.
Hydrogen sulfide, H2S, is a toxic gas responsible for the odor of rotten eggs. The solubility of H 2 S (g) in water at STP is 0.195M.What is the Henry's-law constant of H2S at 0 ° C?
How much heat is required to warm 229 g of ice from -47.1°C to 0.0°C, melt the ice, warm the water from 0.0°C to 100.0°C, boil the water, and heat the steam to 173.0°C?
A 3.00- flask is filled with gaseous ammonia, . The gas pressure measured at 20.0 is 2.15 . Assuming ideal gas behavior, how many grams of ammonia are in the flask
