Introduction This is an investigation to see what happens to the rate of reaction when you put different concentrations of Hydrochloric acid into a conical flask with Marble chips of the same mass. A rate of reaction is how quickly the two or more substances chemically combine. We measured the carbon dioxide in the measuring cylinder that is in the ice cream tub because we kept that the same so we could do the calculation for a rate of reaction. You can find this by doing a calculation: the change in the substance you are measuring divided by the time taken to get that change. The word equation for the experiment we did was: Calcium Carbonate + Hydrochloric acid. The products were Calcium Chloride, Carbon Dioxide, and Water. Sometimes we write the chemical equation because it is easier at any place or time and the equation for our...
