Types of Reactions

There are 5 different types of chemical reactions.

Each of them have a certain format.

1. Synthesis Reaction

2. Decomposition Reaction

3. Single Replacement Reaction

4. Double Replacement Reaction

5. Combustion Reaction

5. Combustion Reaction

A combustion reaction is when all substances in a compound

are combined with oxygen, which then produces carbon

dioxide and water.

Guided Practice.For FunThe Dance.Chris and Rihanna were both single. No one was talking

about "Chris and Rihanna" being together before the dance. Theyboth go to the dance alone. However, they meet at just the perfect

time when Chriss new song is playing. After that fateful meeting no

one ever sees Chris without Rihanna, they are forever referred to as

"Chrianna"

Represent the drama of Chris and Rihanna as a

chemical equation. Use C to represent

Chris and R to represent Rihanna.

If C and R represent elements can you

describe what type of reaction is happening?


9/19

The dance continues.. Later that same evening Jay-Z and Beyonce, who have been

the couple forever, have a heated quarrel and break up.

Represent the drama of Jay-Z and Beyonce

as a chemical equation? Use J to representJay-Z and B to represent Beyonce.

If J and B represent elements can you

describe what type of reaction is happening?


10/19

And theres more Rihanna decides that she wants play hard to get to make

sure Chris really likes her. She finds Jay-Z on the dance floor

and starts dancing with him. The picture below shows what

happened.

Write a chemical reaction for this scenario. Use R to represent

Rihanna, C to represent Chris Brown, and J to represent Jay-Z.

The end of the night In their blissful state, Chris and Rihanna (CR) try to help Jay-Z and

Beyonce (JB) reconcile their differences. After everyone agrees tostop quarreling, Chris asks Beyonce to dance. Jay-Z and Rihanna

decided that they will dance together as well.

Represent the drama between Chris, Rihanna, Jay-Z, andBeyonce in a chemical equation. Use CR to represent Chris and

Rihanna and JB to represent Jay-Z and Beyonce.

What type of reaction does this scenario represent?

Activity Series

We use the Activity Series of Metals to predict whether a single

replacement reaction will occur.


16/19

How it Works: It is used to determine the products of single displacement

reactions. The reaction will only take place if the metal wanting to

replace the other is higher on the series.

Example: Ca + Pb(NO3)2
