A student performed two experiments in which $\text{MnO}_2$ acted as a catalyst to break down hydrogen peroxide. The equation for this reaction is shown. $2\text{H}_2\text{O}_2\text{(aq)} \rightarrow 2\text{H}_2\text{O(l)} + \text{O}_2\text{(g)}$. Which statements are correct?
- A1, 2 and 3 are correct
- B1 and 2 only are correct
- C2 and 3 only are correct
- D1 only is correct
