a) State the variables in this experiment. i) Responding variable: The responding variable is the factor that is measured or observed to see how it changes in response to the independent variable. In this experiment, the volume of gas produced is measured over time to determine the rate of reaction. Volume of gas collected ii) Constant variable: Constant variables are factors that are kept the same throughout the experiment to ensure a fair test. To study the effect of marble size, other factors like the amount of reactants and reaction conditions must be controlled. Mass of marble (or Concentration of dilute hydrochloric acid, or Volume of dilute hydrochloric acid, or Temperature of the reaction) Send me the next one 📸
