Question

Can someone balance this equation for me? I dont understand!
Br2 + S2O32– + H2O → Br1– + SO42– + H+

They should help you

Answer 4

thanks

Answer 5

I dont get how to do this equation

Answer 6

its the same deal just make sure that the number of atoms on one side equals the number on the other side for each elements
Br2 + S2O32– + H2O → Br1– + SO42– + H+

Answer 7

So start with the first side and make an inventory of atoms

Br2 + S2O32– + H2O

Has

2 Br atoms
2 S atoms
33 O atoms
2 H atoms

On the left we have,

Br1– + SO42– + H+

1 Br atoms
42 O atoms
1 S atom
1 H atom

We can balance Br by adding a 2 next to it

Br2 + S2O32– + H2O → 2Br1– + SO42– + H+

Now we have,

On the Right
2 Br atoms
2 S atoms
33 O atoms
2 H atoms

On the Left
2 Br atoms
42 O atoms
1 S atom
1 H atom

so,

Br2 + S2O32– + H2O → 2Br1– + 2SO42– + H+

So Br is balance

Now we have 2 sulphur atoms on the right and 1 on the left so double the amount of SO42-

On the Right
2 Br atoms
2 S atoms
33 O atoms
2 H atoms

On the Left
2 Br atoms
42*2 = 84 O atoms
2 S atom
1 H atom

sulphur is balanced now we need to adjust the amount of Hydrogen and oxygen so we have 84 oxygen atoms make it equal on both sides by playing with the amount of water

Answer 8

I left the reaction as:
Br2 + S2O32– + H2O → 2Br1– + 2SO42– + H+

Balance the amount of oxygen in the reaction then balance the amount of hydrogen

There are faster methods im just using logic though, those videos will give you reliable methods to use to solve these problems

Answer 9

Thanks!! However its not 33 O atoms

Answer 10

its O^2-and 3 under the O

Answer 11

yeah well it doesnt really change how you find the answer

Answer 12

Not to come off as a jerk but next time give the person answering your question time to answer rather than opening the same question again, it is pretty rude. Also kind of unnecessary.

Answer 13

sory

Answer 14

new to this

Answer 15

its fine no big deal
