Physical and chemical properties, such as color, density, boiling point, solubility, conductivity, and flammability, A. do not depend on the amount of the substance. B. depend on the amount of the substance. C. have the same values for all substances. D. are always different between substances.

Astudent conducts an experiment to determine how the amount of water given to a plant affects its growth. what is the independent variable for this experiment?

Nh4no3 n2o + 2h2o a chemist who is performing this reaction starts with 160.1 g of nh4no3. the molar mass of nh4no3 is 80.03 g/mol; the molar mass of water (h2o) is 18.01 g/mol. what mass, in grams, of h2o is produced?

Acertain substance has a solubility of 12 grams in 100 grams of water at 20°c. this means that when 12 g of the substance are dissolved in 100 grams of water, the solution will be saturated when 12 g of the substance are dissolved in 100 grams of water, the solution will be dilute the substance will begin to dissolve when 12 grams are present in solution when 12 grams of the substance are stirred into a beaker with 100 g of water, it will begin settling at the bottom
