There are a lot of chemical reaction in chemistry.It is very hard to remember all chemical reaction correctly.I want to know,if you know any tricks,techniques to remember chemical reaction, please tell me.
Best answer will get 10 marks.

the non-organic reactions have some patterns:

1)combinatin reactions:
ex: H2+Cl2--->2HCl
pattern: A+B--->AB (if A is more electropozitive or BA if B is more el.poz.)
or ex: Na2O+H2O--->2NaOH
pattern: MO+ H2O--->MOH (M->any kind of metal)

2)substitution:
ex:Cl2+2H2O---->2HCl + O2
pattern: A + BC---->BA+C ( if A is more electronegative than C)
or ex: 2Na+2HCl--->2NaCl+ H2
pattern: A+BC--->AC+B (if A is more electropositive element than B)

3)double subtitution:
ex: HCl+NaOH---> NaCl+ H2O
pattern: AB+CD--->AD+CB


other tips:
Metal+H2O----->MetalOH + H2
MetalO+H2O---->MetalOH
Non-metal+H2O---->acid+O2
Non-metalic oxide+ H2O---> acid+O2
metallic oxide+ acid----->salt+H2O
MetalOH +acid----->salt+H2O

You generally never need to memorize a chemical reaction.
What you do need to do is make sure you know the patterns of the types of chemical reactions and how they work so you can reconstruct them on your own.

Some chemical reactions are easy to remember,
2 H2 + O2 --> 2 H2O
Other reactions are difficult,
5 C12H22O11 + 48 KNO3 --> 36 CO2 + 24 N2 + 24 K2CO3 + 55 H2O

But if you know the types of reactions and get a feel for how certain chemical react with others (as well as basic Stoichiometry skills) then you'll be able rebuild the reaction from scratch.
A lot of this is just a skill you acquired through lots of practice, don’t worry just keep at it.

Im an atheist and that i dont say this. properly ok yeah particular sufficient the middle is an organ which of route keeps you alive and the mind has all kinds of chemical reactions which reason emotions.. yet that does no longer make love some thing else than what it is.. love is particular and a particular component that ought to correctly be positioned onto that one human being on your existence and no one else, atleast in my adventure. Does it matter which organ it got here from?.. in case you want to coach it with the aid of affirming your heart, because it is now noted as an organ of love then theres no longer some thing incorrect with that.. that is going to easily be an expression and a way of expressing your love for someone. Love is a really functional emotion that is going deeper than chemical reactions contained in the mind yet, it is how technological awareness knows it. because, if this become very few random component that surpassed with the aid of then human beings must be falling inlove with a lot of human beings, and at the same time as this may properly be the case i dont imagine its actual love. I also imagine that some human beings were purely meant.. they are so properly matched and their love is extremely good, someplace alongside the strains they matched and were meant to compare.

Everyone learns differently. Learning requires curiosity (the tough part in chemistry!), frustration and repetition.

I was able to remember chemical equations by writing them as a list on a piece of paper. I covered one side of the equation and tried to guess at what the other side was. If I got it right, I could progress to the next equation. I was ready for the test when I worked through the whole list forward and backward.

It is amazing how much you can memorize this way.

Anyone taking organic chemistry in college would tell you that there are very few tricks. With hundreds of "types" of reactions, you just have to learn them.

i face the same problem but i almost solved it
for organic understand the mechanisms
for inorganic just byheart it except some which you can understand
