Chemistry · Secondary 4 · Hard · Concentration and pressure
In an experiment, excess magnesium reacts with 40 cm³ of 1.0 mol/dm³ hydrochloric acid. The reaction is repeated using the same volume and concentration of nitric acid instead. How will the volume of hydrogen gas produced and the time taken for the reaction to finish compare with the first experiment?
- Same volume of gas, similar time taken.
- Same volume of gas, but much shorter time taken.
- Half the volume of gas, same time taken.
- Half the volume of gas, longer time taken.
