Investigating Factors That Affect Rates Of Reaction Aim: How does the mass of calcium carbonate affect its rate of reaction with hydrochloric acid? Hypothesis: I hypothesize that when the mass of the calcium carbonate increases‚ the rate of reaction of the calcium carbonate and hydrochloric will also increase. The collision theory states that the more successful collisions there are within the reaction‚ the faster the rate of reaction. When the mass increases‚ so does the number of particles

distances. • Get an overview of the solar system. Introduction It is easy to flip to the index of an astronomy textbook to discover that‚ say‚ the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible)‚ however‚ to picture this distance in the human mind. In this exercise‚ we will learn to access the often unpalatable distances encountered in astronomy by simply scaling the huge distances to more recognizable‚ pedestrian numbers. So long as every distance
