• 🙃 Balancing the equation ensures that the number of atoms is the same on both sides.
• 😑 The net ionic equation only includes the ions that participate in the reaction.

Transcript

in this video we're going to go over single replacement reactions so let's start with the first one let's say if you have aluminum metal placed in a solution of copper chloride what are the products of this reaction and also how can you write the net ionic equation so in a single replacement reaction aluminum metal is going to replace copper metal ...

Questions & Answers

Q: How do you determine the products of a single replacement reaction?

The reactivity of the elements involved, determined by their position in the activity series, determines the products. The more reactive element will replace the less reactive ion in the compound.

Q: What is the process for balancing a single replacement reaction?

To balance the reaction, adjust the coefficients in front of the compounds so that the number of atoms of each element is the same on both sides of the equation.

Q: How do you write the net ionic equation for a single replacement reaction?

Start with the total ionic equation, which includes all ions present in the reaction. Then, eliminate spectator ions, which are ions that appear on both sides of the equation. The remaining equation is the net ionic equation.

Q: What determines if a single replacement reaction will occur?

The activity series can be used to determine if a reaction will occur. If the metal doing the replacing is higher in the activity series than the metal being replaced, the reaction will occur.

Summary & Key Takeaways

• Single replacement reactions involve a pure element replacing a metal ion in a compound.

• The products of the reaction depend on the reactivity of the elements involved.

• The net ionic equation represents the reaction after eliminating spectator ions.
