Question

Whats the best way to memorize chemistry equations?

Answer 1

The best way is don't memorize chemical equations.

Explanation:

Use the periodic table to determine the oxidation numbers of the elements and then use the oxidation numbers to balance the equation. There are thousands of chemical equations trying to memorize them all is a waste of effort. Learn how the periodic table works and use that to balance the equations. all

The left side of the periodic table is generally positive. I A has an oxidation number of +1 II A +2 III A + 3 IV A +4+2 or -2, -4 VA +5 or -3 VI A +6 or -2 VII A + 7 +5, +3 or -1 VIII A 0 ( VIII is the ideal that all other elements want to be like 8 outer valance electrons.

To balance an equation use algebra directed or integers .

For example Ba+2 ( IIA) and Cl-1 ( VII A) combine them so that the sum is zero.

`1 xx +2 + 2 xx -1) = 0` This means that the formula would be

`BaCl_2`
