I'm sorry some of the questions skipped, I glitched the test I think. So I got 7/10 because it skipped 3 questions.

1. What is the maximum mass of Chromium, Cr, that can be extracted from 76g of chromium (III) oxide Cr₂O₃?
52g

2. The reaction between hydrochloric acid and calcium carbonate is shown .
CaCO₃ + 2HCl à CaCl₂ + H₂O + CO₂
Which volume of 1.0mol/dm³ hydrochloric acid is needed to react completely with 1.0g of calcium carbonate (M_r = 100)?

20cm^3

5. A mixture of 16.0g of oxygen and 16.0 g of hydrogen is ignited.
2H₂(g) + O₂(g) à 2H₂O(l)
What mass of water is produced in the reaction?

18.0g

6. Sodium hydrogencarbonate decomposes on heating:
2NaHCO₃ à Na₂CO₃ +H₂O + CO₂
In an experiment, a 5 mol sample of sodium hydrogen carbonate was heated.
What volume of carbon dioxide, measured at room temperature and pressure, would be evolved?

60 dm^3

7. 300g of the vapour of the element arsenic As, has the same volume as 71g of chlorine gas, measured at the same conditions of temperature and pressure. What is the formula of the arsenic molecule in the vapour?

As₄


8. Sodium reacts with water according to the equation below.
2Na + 2H₂O à 2NaOH + H₂
Which volume of hydrogen is produced at rtp when 4.6g of sodium reacts?

2.4dm³


9. An element Z forms a hydride with formula ZH₃. This hydride contains 91.2% of Z by mass. What is the relative atomic mass of Z?

31

10. 2 CO(g) + O₂(g) à 2 CO₂(g)
20 cm³ of oxygen are reacted with 20 cm³ of carbon monoxide.
At the end of reaction, what are the volumes of gases remaining?

I didn't get to see the choices for this question, so try 10 cm^3 if there's such an option. Play safe, though. Work this question out yourself and doublecheck.
