Which of the following is a chemical change?

White liquid and red liquid combining to make pink liquid

Why is bubbling often a signal that a chemical reaction is occurring?

It shows that a new substance (gas) is being formed

It shows that the temperature is changing

It shows that the state of matter is changing

It shows that a substance has reached its boiling point

What are the reactants in this chemical equation?

Water, carbon dioxide, heat and light

propane, oxygen and carbon dioxide

Taylor mixes road salt with baking soda in an open beaker. The mass of the substances before the reaction is 20 g. When the substances are mixed, they react - they form bubbles and the temperature rises. The mass after the reaction is 19 g. Why did the mass decrease?

The mass decreases if a reaction takes place in an open system and one or more products is a gas

Mass always decreases during a chemical reaction

The mass increases because a new substance is formed

Taylor made a mistake because the mass can never change in a chemical reaction

The difference between an atom and a molecule is that:

Molecules are made of more than one atom stuck together

Atoms are made of more than one molecule

Molecules are made of two atoms of the same type stuck together

Molecules are small and atoms are large.
