Answer:
Explanation:
In order to balance equations, simply alter coefficients until all elements are equal on both sides of the reaction symbol ”—>”:
1HBr + 1KOH —> 1KBr + 1H2O
The reaction is already balanced
3HF + Fe(OH)3 —> FeF3 + 3H2O
To match the 3 Flluorines on the right hand side, add 3 to HF and then add 3 to H2O to compensate for the increase in hydrogens.
2HCl + Ca(OH)2 —> CaCl2 + 2H2O
The Chlorine must be balanced, and then hydrogen must be balanced.
Hope this helps! If it did, I would appreciate if you provided brainliest!
