VARIABLES The variables in this experiment are: · The mass of the marble chips · The size of the marble chips · The amount of hydrochloric acid used · The concentration of hydrochloric acid used · The temperature of the hydrochloric acid · The speed at which CO2 is produced · Equipment used My input variable is the temperature of the hydrochloric acid. I have chosen this because, according to the kinetic theory, the temperature should increase the speed and energy of the particles, therefore there are more collisions between particles, and the rate of reaction increases. My output variable is the speed at which CO2 is pro... Posted by: Sandeep Jador Limited version - please login or register to view the entire paper. |
