Quiz:

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.Which is correct about conservation of mass?

Mass is created during a reaction. The total mass of the reactants equals the total mass of the products. Mass is either created or destroyed during a reaction. The total mass of the reactants equals the total mass of the products (if you performed the experiment correctly).
