Hi I am in biology and we are working on balancing equations I have done a whole lot of the but I have a few that are giving me a whole lot of trouble I hope someone can help:


KEY:I didn't know how to write the numbers on a lower line so if its so post to be on a lower line it has a ~ behind it .

1)H2~ +N2~ -> NH3~

2)Cu +O2~ -> Cu2~O

3)Ag +I2~ ->AgI

4)Al +Br2~ -> AlBr3~

5)Fe +F2~ -> FeF3~

6)Mg +P ->Mg3~P2~

7)K +N2~ ->K3~N

:) :) :) Iam so grateful for any help that is giving to me :) :) :)

Hey, I think these are the answers although it has been a few years since I have taken Chemistry

1)3H2+N2 -> 2NH3

2)4Cu +O2 -> 2Cu2O

3)2Ag +I2 ->2AgI

4)2Al +3Br2 -> 2AlBr3

5)2Fe +3F2 -> 2FeF3

6)3Mg +2P ->Mg3P2

7)6K +N2 ->2K3N

:) :) :) Thanks so much for your help :) :) :)
