-According to the collision theory of reactivity, reactions occur when reactant molecules effectively collide. For an “effective collision” to occur, the reactant molecules must be oriented in space correctly to facilitate the breaking and forming of bonds and the rearrangement of atoms that result in the formation of product molecules.
<span>=> Keep the reactants in separate containers is that best statement that applies to the theory of preventing a dangerous reaction from occuring. Keeping those reactions in a separate container will keep it from mixing and making unpleasant reaction.</span>
Gravity is when you drop something, but in this case you aren’t dropping the ball. It definitely isn’t chemistry because you aren’t changing molecules or anything so that only leaves A which is the most reasonable answer anyways.
