Lesson Check 1 - Net Ionic Reactions

Choose all states that should be written as ions in net ionic equations.

• liquid

• solid

• aqueous

• gas

If the reaction produces 2 aqueous products, then no reaction (NR) actually occurred. (a)  

• True
• False

Net Ionic equations include all ions. even the spectator ions.

• True

• False

Spectator ions can cancel out of a final net ionic equation when they ....

• only when they are a reactant

• appear on both sides of the equation

• only when they are a product

• spectator ions should NEVER be canceled out

(Cu)₂SO₄

• The charge for copper in this compound is +1

• The charge for copper in this compound is +2

• Copper can only have one charge.

• You can not tell the charge of copper from the given information.

All acids will ionize about 100% in an aqueous solution.

• True

• False

When liquid water is a product in a net ionic equations, it should be written as ions (OH^- and H^+) .

• True

• False

Net ionic equations must be balanced in regard to both the elements and charge.

• True

• False

In the molecular equation, everything is broken up into ions.

• True

• False

Spectator ions ALWAYS participate in the reaction.

• True

• False
