Questions & Answers

Q: How do you determine if a reaction is a single replacement or double replacement reaction?

In a single replacement reaction, one element replaces another in a compound. In a double replacement reaction, the positive ions in two compounds switch places.

Q: Why is it important to know solubility rules and the activity series?

Solubility rules help predict whether a compound is soluble or insoluble in water, which is important for determining if a precipitation reaction will occur. The activity series helps determine which element is more reactive and will displace another in a single replacement reaction.

Q: What is a net ionic equation?

A net ionic equation shows only the species that participate in a chemical reaction. It eliminates the spectator ions, which are ions that appear the same on both sides of the equation.

Q: How do you balance a net ionic equation?

To balance a net ionic equation, ensure that the number of atoms and charges is the same on both sides of the equation. Adjust the coefficients as needed.
