The equation shows the reaction of lithium with water:
2Li(s)+2H2O(l)→2LiOH(aq)+H2(g) 2\text{Li(s)} + 2\text{H}_2\text{O(l)} \rightarrow 2\text{LiOH(aq)} + \text{H}_2\text{(g)} 2Li(s)+2H2O(l)→2LiOH(aq)+H2(g)A sample of lithium of mass 0.084 g reacts with excess water.
Calculate the volume of hydrogen gas, in cm3\text{cm}^3cm3, produced at room temperature and pressure (rtp).
The volume of one mole of a gas at rtp is 24 000 cm3.Note: Ar(Li)=7. \text{The volume of one mole of a gas at rtp is } 24\,000\text{ cm}^3. \quad \text{Note: } A_r(\text{Li}) = 7. The volume of one mole of a gas at rtp is 24000 cm3.Note: Ar(Li)=7.
