REACTIONS IN MATTER
Pre-test:

...

Combination, decomposition, combustion, single replacement, and double
replacement are 5 common types of chemical reactions
...
A combination reaction or sometimes called
synthesize reaction produces a single substance from multiple reactants
...
A combustion reaction is a reaction in which a substance reacts with
oxygen gas, releasing energy in the form of light and heat, one of its reactant must be
O2
...
Lastly, A double-replacement reaction occurs when parts of two
ionic compounds are exchanged, making two new compounds
...
What is balancing in chemical reaction? How does it work?
A balanced chemical equation occurs when the number of the atoms
involved in the reactants side is equal to the number of atoms in the products side
...
To balance a unbalanced atoms, we need to make use of coefficients
...
To balance a
chemical reaction, we need to (1) Count the atoms of each element in the reactants and
the products and (2) use coefficients; place them in front of the compounds as needed
...
How much do you know about balancing an equation in a chemical reaction?
With all honesty, it’s my first time taking this topic because we didn’t study
this on my senior year since I am a GA strand student
...
Sadly I am a product of GA strand so I have no idea
about the said topic

Dewitt explain the

Types of Chemical Reactions by Tyler

concept, he talks very well, he

Dewitt published in the year 2015 had

discusses the details very well and I

made my life easier in recognizing the

really understand what he is saying
...
As

communication to his viewers is so

I mentioned above, I don’t have any

good

5M views
...
His video deserves

very helpful tool not just to me but also

its views and he deserves his

to those GA Strand students who take

subscribers
...


and helpful

____ HBr + ____ Al(OH)3  ____ H2O ____ AlBr3
3HBr + Al(OH)3 → 3H2O + AlBr3
