Calculate the boiling point of a 2.97m aqueous solution of ethylene glycol, a nonvolatile nonelectrolyte.
An excess sample of solid Ag2SO3 is added to 100 mL of water. After equilibrium is achieved between the solid and its aqueous ions the silver ion concentration is found to be 2.486e-05 Use this information to find Ksp for Ag2SO3
The exothermic chemical reaction CO(g) + H2O(g) CO2(g) + H2(g) has Kc = 0.034 at 25°C. We currently have a flask containing all the components listed in this equation at equilibrium at 25°C. Subsequently, we will either (1) add some H2 to the flas..

how many square meters of floor space are there in a room which has 225.0 square yard of floor space 1 m=39.37 in, 1 yard =36 in.
Two different solutions were prepared. Solution A was prepared by dissolving sodium acetate in methanol and solution B was prepared by adding potassium methoxide to acetic acid.
If a sodium hydroxide solution is prepared by dissolving it in a volumetric flask and diluting to the line with mixing, will the level be on the line, below the line, or above the line on the following day?
estimate the amount of carbon dioxide (in tonnes) that is consumed over a 6-month period by the forest, assuming trees are 50% glucose and 50% water. How much sunlight (in GJ) has the forest absorbed in that period?
