A student investigated the rate of the reaction between zinc granules and dilute sulfuric acid.
The equation for the reaction is: Zn(s)+H2SO4(aq)→ZnSO4(aq)+H2(g)\text{Zn(s)} + \text{H}_2\text{SO}_4\text{(aq)} \rightarrow \text{ZnSO}_4\text{(aq)} + \text{H}_2\text{(g)}Zn(s)+H2SO4(aq)→ZnSO4(aq)+H2(g)
Which state symbol in this equation does not represent one of the three states of matter?
What two pieces of measuring apparatus could the student use to find the rate of production of hydrogen gas?
The table below shows the results of the investigation:
| Time in sss | Volume of hydrogen gas collected in cm3\text{cm}^3cm3 |
|---|---|
| 0 | 0 |
| 10 | 25 |
| 20 | 40 |
| 30 | 49 |
| 40 | 54 |
| 50 | 55 |
| 60 | 55 |
Give three conclusions that can be drawn about the rate of reaction from this data.
The student repeated the investigation using dilute sulfuric acid at a higher temperature. All other variables were kept the same. Which two of the following statements are correct?
