What are some ways you would suggest to learn different chemical equations easily? they are pretty confusing to me and i am atressig about it. How to learn them! I dont want to use the "ratta" method. So a way hich i can use to understand equations. Specially those equations which have catalysts in it. a same equation can have different products just by changing the catalyst. So any way to remember this also? Please give an explained answer. |
