Look at the reactants of a chemical reaction and predict the products. If you got the correct compounds but in a different order than was the correct answer then use the "I was RIGHT" button.
3 things to always remember when balancing chemical equations:
1) HX + Y(OH) --> XY + H(OH) No matter what elements X and Y are; any double replacement reaction with a hydroxide bonding to a hydrogen can be written as H₂O *OR* H(OH). Below in combustion is the only time I use H₂O, and with all DR reactions I use H(OH).
2) BrINClHOF diatomics
3) Do NOT break up polyatomics
