While a student was trying to determine the volume of a metal sample using water displacement, some water splashed out of the cylinder when the metal was dropped in. Would this error cause the calculated density to be too high or too low?

For which one of the following reactions is the value of δh° rxn equal to δh° f for the product? a. 2 h2 (g) + o2 (g) → 2 h2o (l) b. n2 (g) + o2 (g) → 2 no (g) c. 2 h2 (g) + o2 (g) → 2 h2o (g) d. h2o (l) + 1/2 o2 (g) → h2o2 (l) e. none of the above

Does the temperature affect the solubility of sugar and salt in water? if it does tell me like different temperatures with different solubilities so i can sketch down a graph

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass
