Which substances will be present in the reaction vessel at the end of the reaction between 1.5 g of magnesium and 50.0 cm3 of 1.0 mol dm⁻³ hydrochloric acid? $\ce{Mg(s) + 2HCl(aq) -> MgCl2(aq) + H2(g)}$ A. $\ce{HCl(aq)}$, $\ce{MgCl2(aq)}$ B. $\ce{Mg(s)}$,…

For the runs with 0.40 and 0.80 $\mathrm{mol\,dm^{-3}}$ $\ce{HNO3(aq)}$, suggest which reactant, $\ce{CaCO3(s)}$ or $\ce{HNO3(aq)}$, was the limiting reagent. Give a reason for your answer.

If the reaction with 0.80 $\mathrm{mol\,dm^{-3}}$ $\ce{HNO3(aq)}$ went to completion, the theoretical mass of $\ce{CO2(g)}$ released would be 1.76 g. (i) Use the graph to determine the mass, in g, of $\ce{CO2(g)}$ actually released in this reaction. (ii)…

(i) Write a balanced equation, with state symbols, for this reaction. (ii) Deduce which of the two reactants runs out first, that is, which one limits the reaction. Use sections 1, 4 and 7 of the data booklet. (iii) Calculate the volume, in $\mathrm{dm^3}$,…

90.0 $\mathrm{cm^3}$ of buta-1,3-diene and 150.0 $\mathrm{cm^3}$ of hydrogen are mixed in a container at 450 K and 101 kPa and react to form butane only. Determine the maximum volume of butane that can be formed, measured at the same temperature and pressure.

What are the limiting reactant and the theoretical yield of hydrogen when 0.30 mol of aluminium reacts with 0.60 mol of hydrochloric acid? $\ce{2Al(s) + 6HCl(aq) -> 2AlCl3(aq) + 3H2(g)}$ In each option the limiting reactant is given first and the theoretical…

30 $\mathrm{cm^3}$ of butane was completely burned in 250 $\mathrm{cm^3}$ of oxygen according to the following equation. $\ce{2C4H10(g) + 13O2(g) -> 8CO2(g) + 10H2O(l)}$ What volume of oxygen remains unreacted, measured at the original conditions? A. 55…

Student B pipetted 30.00 $\mathrm{cm^3}$ of the potassium hydroxide solution into a 150 $\mathrm{cm^3}$ glass beaker and added the nitric acid from a burette in portions of 4.00 $\mathrm{cm^3}$, recording the steady temperature after each addition. Volume of…

0.30 $\mathrm{dm^3}$ of nitrogen is mixed with 0.60 $\mathrm{dm^3}$ of hydrogen and the mixture reacts as completely as possible. All gas volumes are measured at the same temperature and pressure. $\ce{N2(g) + 3H2(g) -> 2NH3(g)}$ What volume of ammonia, in…

Sucrose, $\ce{C12H22O11}$, is hydrolysed with excess water and the glucose formed is then fermented. $\ce{C12H22O11(aq) + H2O(l) -> 2C6H12O6(aq)}$ $\ce{C6H12O6(aq) -> 2C2H5OH(aq) + 2CO2(g)}$ $M_\mathrm{r}$ of $\ce{C12H22O11}$ = 342.34 $M_\mathrm{r}$ of…

Equal volumes of the gases $\ce{Q2}$ and $\ce{R2}$ are mixed in a sealed container and react until one of them is used up, forming the gas $\ce{QR2}$. The volume of $\ce{QR2}$ formed, measured under the same conditions, is 50 $\mathrm{cm^3}$.…

The dotted line shows the volume of hydrogen produced when an excess of magnesium ribbon is added to 50 $\mathrm{cm^3}$ of 2.0 $\mathrm{mol\,dm^{-3}}$ hydrochloric acid. Which curve shows the volume of hydrogen produced when the same excess of magnesium ribbon…
