Janice notices that the reaction rate increases if she heats the solution. explain why a)increasing the temperature decreases the energy. b)increasing the temperature increases the molecular motion. c)increasing the temperature reduces the collision frequency d)increasing the temperature divides the solubility of the solute

What mass of glucose is produced when 54g of water react with carbon dioxide

The sum of the oxidation numbers in a neutral compound is always

In a laboratory determination of the atomic weight of tin, a sample of tin is weighed in a crucible. nitric acid is added, and the reaction proceeds to give a hydrated tin(iv)oxide plus no2and h2o. the hydrated tin(iv)oxide is then heated strongly and reacts as follows: sno2.xh2o(s)sno2(s)+ xh2o(g)the sno2is finally cooled and weighed in the crucible. explain the effect on the calculated atomic weight of tin that would result from each of the following experimental errors: (a)considerable spattering occurs when the nitric acid is added to the tin.(b)the hydrated tin(iv)oxide is not heated sufficiently to change it completely to tin oxide.
