Worked Solution & Example Answer:A student used the apparatus shown in Figure 3 to investigate the reaction between marble chips and dilute hydrochloric acid - Edexcel - GCSE Chemistry - Question 2 - 2023 - Paper 2
Step 1
Plot the results shown in Figure 4
Answer
- On the grid, mark the points (0, 0), (1, 52), (2, 78), (3, 91), (4, 97), (5, 100), and (6, 100).
- Ensure that each point is accurately represented on the graph.
- Draw a smooth curve connecting the points, representing the trend of gas volume over time.
