Question

balance the equation:

Na+H2O.....NaOH+H2

Answer 1

I know that the Na is fine, but how do i get H to equal 3 molecules on the left side?

Answer 2

oxygen in fine, too.

Answer 3

well sometimes when you add things the won't be fine anymore. you just have to play with it, eventually u will get used to it

Answer 4

so for this one if i told you to put a 2 in front of H2O could you do it

Answer 5

Na+2H2O.......NaOH+H2

but now hydrogen equals 4 on the left, and 3 on the right.

Answer 6

yes so you want to add something to the NaOH

Answer 7

let me help you out a little. Na +2H2O=2NaOH+H2 is that balanced now?

Answer 8

Na+2H2O........2NaOH+H2
no, because now there are 2 Na molecules on the right, and 1 on the left

Answer 9

ok, so how would you fix that?

Answer 10

since you have 1 Na on the left and 2 Na on the right you can easily just add a 2 to Na

Answer 11

of course! so:

2Na+2H2O.........2NaOH+H2

Answer 12

yes! exactly

Answer 13

thank you so much!!!!

Answer 14

your welcome!

Answer 15

think of H2O as HOH and look at it by seeing a hydrogen and an hydroxide and it well help you understand it better

Answer 16

the balanced equation is 2Na +2HOH-->2NaOH+H2 or 2Na + 2H2O--> 2NaOH+H2
