# 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!

## Question 5

Q1.H₂ (g) + Cl₂ (g) → 2HCl (g). Starting with 4 g of hydrogen, what mass of hydrogen chloride would be produced? (Relative atomic masses: H = 1; Cl = 35.5)

1/5

Q2.Which of these is NOT a reason why the percentage yield is less than 100%?

2/5

Q3.Which of these is a reason for wanting high atom economy?
