Types of Chemical Reactions

This chemistry video tutorial explains how to classify different types of chemical reactions such as synthesis reactions or combination reactions, decomposition reactions, single replacement reactions, combustion reactions, double replacement reactions, precipitation reactions, acid base neutralization reactions, redox reactions, and gas evolution reactions. This video contains plenty of examples and practice problems.

Types of Chemical Reactions

1- Combustion Reaction
• in combustion, something is burning and it releases a lot of heat energy.
• if you see CO2 and water in the product then it's a combustion reaction.
• All "Combustion" reactions are "Redox Reactions".

2- Synthesis\Combination reaction
• A + B = AB
• you simply combine the reactants to make the product.
• If two pure elements combine to form a compound then it's a "Redox Reaction".
• If two small compounds combine to form a large compound then it's probably NOT a "Redox Reaction".

3- Decomposition reaction
• AB = A + B
• the opposite of the Synthesis\Combination reaction: simply breaks down reactants to make the product.
• heat and electricity cause decomposition reactions
• If a compound breaks down into pure elements then it's a "Redox Reaction".
• If a large compound breaks into two small compounds then it's probably NOT a "Redox Reaction".

4- Single replacement reaction
• A + BC = AC + B
• Just as the name says, a single molecule from the same equation replaces another.
• For the most part, metals tend to replace metals and nonmetals tend to replace nonmetals.
• All "Single Replacement" reactions are "Redox Reactions".

5- Double Replacement reaction
• AB + CD = AD + BC
similar to the Single replacement reaction; however, this one is double, and completely switches elements' places up.
• Both of the reactants must be aqueous
• When a double replacement happens between two aqueous solutions and the products all remain aqueous then no reaction took place.
• A "Double Replacement" reaction is NEVER a "Redox reaction"
• Double Replacement reaction types:
- if a double replacement of two aqueous products happens and you find a solid in the product then it's called a "Precipitation Reaction".
- If a double replacement happens between a strong acid and a strong base it will produce water and salt and will be called "Acid-Base Neutralisation Reaction".
- if a double replacement of two aqueous products happens and you find a gas in the product then it's called a "Gas Evolution Reaction".



-Redox Reactions: Also called "oxidation-reduction reaction", is any chemical reaction in which the oxidation number of atoms changes.
-Methane(CH4) is also called: Natural gas.
-Almost all ionic compounds are considered salts.

Synthesis: Putting Together
Decomposition: Breaking Up
Single Replacement: “I’m leaving you for your friend”
Double Replacement: “Wife Swap”
Combustion: “Taylor Swift”

All Credits to my science teacher

The Taylor Swift one: does the same thing over and over again. Gets a boy. They break up. She writes a song.

Hope this helps!

I seriously think you're the best teacher i've ever had. I really understand when you teach me

[LemmieFagrzhe]

What I love about watching your videos is that you get into detail and really explain it in an organized and complex manner without getting too messy. Its perfect.

[tanviudgiri]

had to watch this for a class and I’m actually surprised at how easy it was to follow, and how much I learned!

[Anonymous-bczl]

honestly i've searched so many videos to help me understand this and you finally saved me!

[lovelynpious]

when i read the notes i didn't understand but after watching this tutorial, i clearly understand and can differentiate between different types of reactions. thanks alot

[moroccaninsider.DarSsiba]

Would you please tell how we can find out when it is aqueous, liquid or solid?

[muhsinadam]

i dont know where i would be in life without this guy

[angelboardley]

I really wish I would have known about your channel when I was in college it would have saved me a lot of time and stress. Thank you for your content. It is helping me get into medical school!

[krishnaswamy]

What would I do without you🤔 You have helped me so much. I have watched your videos multiple times. As a gratitude, I watch all the advertisements so you get paid. I wish you were my chem teacher growing up. Your students are the lucky bunch! 🙏🙏🙏🙏🙏

[allyfenton]

thank you again for what u do for the chem community
god bless

[zvtukwu]

I had try to understand chemistry basics from 2 years . Finally i got it by you ❤

[raikhonaatakhanova]

it became so interesting to me that I did not notice how 40 minutes passed, thank you very much

[ARCHER-chxn]

Me studying for exam that is 3 hours from now

[georgesadler]

Professor Organic Chemistry Tutor, thank you for explaining and analyzing different types of Chemical Reactions in AP/General Chemistry. All Chemical Reactions come with different compounds. Breaking down large compounds into small compounds is an excellent way to comprehend Chemical Reactions. This is an error free video/lecture on YouTube TV with the Organic Chemistry Tutor.

[angelasy]

THANK YOU SO MUCH FOR THIS.
I AM IN NEED FOR THIS KIND OF LESSON. ❤

23:50 How do you know when a product is solid vs aqueous/soluble? Just memorize everything?
