By definition, a chemical reaction is a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Chemical reactions can be used to do many daily tasks such as cooking and bodily functions. The reaction rate is the speed at which reactants are converted into products. In the lab done, the purpose was to look at the various ways a reaction rate can be changed. Multiple factors could create different rates at which the reactant will become products. Some are temperature change, surface area, concentration, and using a catalyst. An example given was acidic rain falling on marble statues. As an alternative to natural occurring acid rain, in the lab Hydrochloric acid was used to show how marble and the reactants, marble and Hydrochloric acid could produce water, carbon dioxide, and calcium chloride.
Safety is very important when working with acids. Some of the hazards when handling acids are that they are dangerous to human tissue. They may also cause chemical burns, respiratory distress and fire hazards. The

In using the larger rocks it increased the collisions of the molecules happening in the reaction. In this experiment, predictions were made from past knowledge on the topic. Data was taken on the powder, large, and small marble rocks. The small and powder went over the five minutes so no data was actually recorded. The large marble rocks did have a reaction that was able to be collected. Within the first minute, half an inch of water was removed out of the test tube. The errors that occurred in the experiment were not sealing the setup, acids not being kept at room temperature, and human miscalculation. Some ways that could have prevented those errors would have been to check the setup with precision and keep the acids at a room temperature and not below
