Question

how can i memorize chemical equations

Answer 1

What do you mean for a test or something?
in that case i'd put them in my graphing calculator :)

Answer 2

For organic reactions, it follows a certain pattern. Understand that pattern and all the compounds will follow the same pattern.

For inorganic, you have to learn them. Sometimes you can understand, for example, if a carbonate reacts with a acid (say) , then it will always liberate CO2.

For complex ones, you could try and remember them in a kind of riddle or song or mnemonic (i did that).

Another way is( for equations like this):

K2Cr2O7 + 14 HCl = 2 KCl + 2 CrCl + 7 H2O + 5 Cl2

I just remembered that there are 14 moles of HCl. That is also a good way. If you are doing high school level equations, most of the reactions will give usual products, not weird ones.

Otherwise, try breaking the two reacting compounds ( this can be followed very rarely) into ions and then exchange the ions....


Something from the above will work :)

Answer 3

Practice solving passage-based questions from the practice tests or use EK. After doing enough of those, any equation, no matter how complex, will be drilled in your head.

Answer 4

Thanks y'all for the tips! I hope this works! :) @thomaster not a test , i have my final exam in june!
