Intro quiz - Recap from previous lesson

Before we start this lesson, let’s see what you can remember from this topic. Here’s a quick quiz!

Q1.What type of reaction happens when a compound breaks down due to heating?

1/5

Q2.Iron oxide + aluminium → iron + aluminium oxide. If there is 160 g of iron oxide, 54 g of aluminium and 112 g of aluminium oxide, what is the mass of iron produced?

2/5

Q3.H₂ (g) + Cl₂ (g) → 2HCl (g). Starting with 2 g of hydrogen, what mass of hydrogen chloride would be produced? (Relative atomic masses: H = 1; Cl = 35.5)

3/5

Q4.What mass of magnesium oxide is formed when 12g of magnesium reacts with oxygen? 2Mg + O₂ → 2MgO

4/5

Q5.What mass of aluminium oxide is produced when 13.5g of aluminium is burned in oxygen? 2Al + 3O₂ → Al₂O₃
