• Water and Oxygen

• Carbon dioxide and Salt

• Hydrogen and Oxygen

To make magnesium chloride you need to use all these reactants, except..................................................

• Hydrochloric acid and Magnesium oxide

• Hydrochloric acid and Magnesium sulfate

• Hydrochloric acid and Magnesium carbonate

• Hydrochloric acid and Magnesium metal

What is used to measure out dilute hydrochloric acid?

• Measuring cylinder

• Beaker

• Test tube

• Flask

What forms as magnesium reacts with the acid?

• Bubbles of hydrogen gas

• Bubbles of nitrogen gas

• Bubbles of oxygen gas

• Bubbles of carbon dioxide gas

What forms as magnesium reacts with the hydrochloric acid?

• Magnesium chloride & Bubbles of hydrogen gas.

• Magnesium chloride & Bubbles of nitrogen gas.

• Magnesium carbonate & Bubbles of oxygen gas.

• Magnesium chloride & Bubbles of chlorine gas.

• Magnesium oxide & Bubbles of carbon dioxide gas.

You were asked to measure out 25 cm³ of dilute hydrochloric acid, which of the following apparatus you are going to use, and why?

Beaker.

Conical flask.

Evaporating dish.

Measuring cylinder.

• Use a measuring cylinder because it measures smaller differences in volume.

• Use an evaporating dish because it measures this amount of volume only.

• Use a beaker because it won't allow the acid to evaporate.

• Use an evaporating dish because it will allow the acid to evaporate faster.
