A student investigates how temperature affects the rate of reaction between hydrochloric acid and calcium carbonate powder. The student measures the time taken for the reaction to produce 50 cm³ of carbon dioxide gas at different temperatures.
A student investigates how the rate of reaction changes when calcium carbonate powder reacts with dilute hydrochloric acid. The student measures the volume of gas produced at regular time intervals. The results are shown in the table below: Time (s) | 0 | 10 | 20 | 30 | 40 | 50 Volume of CO₂ (cm³) | 0 | 45 | 80 | 105 | 120 | 120
A student investigates how temperature affects the rate of reaction between calcium carbonate powder and dilute hydrochloric acid. The student measures the volume of gas produced at different temperatures and records the results in a table.
A student investigates the rate of reaction between sodium thiosulfate solution and dilute hydrochloric acid. The reaction produces a cloudy precipitate of sulfur. The student places the flask over a cross drawn on paper and records how long it takes for the cross to disappear. The student repeats the experiment using sodium thiosulfate solution at a higher temperature.
A student investigates the reaction between calcium carbonate chips and dilute hydrochloric acid. The reaction produces carbon dioxide gas. The student wants to compare how quickly the reaction happens using large chips compared to powdered calcium carbonate.
