What is the original source of Hydrogen before it become Hydrogen gas?

• H2O (Water)

• HCℓ (Acid)

• It started as a gas

• Magnesium Metal

What does the Hydrogen need before it can become Hydrogen gas?

• Electrons

• Magnesium

• Protons

• Oxygen

How does Hydrogen obtain the electrons it needs to form a gas?

• Hydrogen collides with the atmosphere

• Hydrogen collides with the Chlorine in HCl

• Hydrogen collides with the Magnesium

• Hydrogen does not need electrons

1.2M is a very strong acid made of a ratio larger than 50/50 acid to water.

• True

• False

If we reacted 1 atom of Magnesium, how many H2 gas molecules could we make?

• None

• 1

• 2

• 4

How many HCl molecules are needed to react with one Magnesium atom?

• 0

• 1

• 2

• 3

If we produced 10 molecules of H2 gas, how many HCl molecules were needed?

• 1

• 5

• 10

• 20

What is the end result of the Chlorine in this reaction?

• The Chlorine becomes a gas

• The Chlorine disappears

• The Chlorine finds more Hydrogen to bond with

• The Chlorine

  bonds with the used Magnesium.
