Consider the reaction below. mg(s) + 2hcl(aq) mc019-1.jpg h2(g) + mgcl2(aq) what is the most likely effect of an increase in pressure on this reaction? the reactant surface area increases. the reaction rate decreases. the reaction is not affected at all. the reaction stops completely.

vapour or gas assuming atmospheriv pressure

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
