Read them regularly and at the end of the day, try to write at least five reactions a time with their mechanisms.
Try to reach examples where that reaction takes place.
You can look after the conversion reactions too.
This way, you can find a loop between different reactions and memorise them easily.

What are the basic chemical equations?

A chemical equation shows the starting compound(s)—the reactants—on the left and the final compound(s)—the products—on the right, separated by an arrow.
In a balanced chemical equation, the numbers of atoms of each element and the total charge are the same on both sides of the equation.

What are the basic formulas in chemistry?

Acetic acidCH3COOHHydrochloric acidHClSulfuric acidH2SO4AcetateCH3COO–

How do you calculate chemical amounts?

The number of moles of a substance in a sample is the mass in g divided by the molar mass, which gives the amount in moles.

Step 1: Find the moles of each element using the equation moles = mass / Mr. Step 2: divide each of the moles by the smallest number calculated. Here, the smallest number of moles is that of oxygen, with 0.025. Step 3: write out the empirical formula using the ratio calculated.
