Calcium carbonate reacts with an excess of hydrochloric acid in a flask. The mass of flask and contents decreases over time as the carbon dioxide escapes. This is shown on the graph. How would the graph look different if the reaction was done with a lower concentration of hydrochloric acid?Lines falls more steeply. Levels out at higher level.Lines falls more steeply. Levels out at same level.Lines falls less steeply. Levels out at same level.Lines falls more steeply. Levels out at lower level (but still above zero).Question 9 of 15 Loading... 10.
