Question

Having some trouble balancing equations..

Answer 1

Write the formula and balance it

hydrogen(g)+oxygen(g)-->water(l)

wouldn't this start as

h+o>>>h20

then just be h2+o2=h2o?

or when you add something to one side, it has to be done to the other? i'm not sure what the rules are..

Answer 2

Yeah, after you balance it, it would be 2(H2) + (O2) -> 2(H20)

Answer 3

You just have to make sure there's the same amount of each element of both sides

Answer 4

Ohh..what you really mean is i can't add numbers at the end of the element, only as the co efficient?

Answer 5

Answer 6

Yup, that's true. Except in this case, oxygen gas and hydrogen gas are naturally diatomic, so they are written as 02 and H2 in gas form

Answer 7

because if i add numbers at the end, i'm CHANGING the molecule instead of multiplying them?

Answer 8

Exactly!

Answer 9

Hmm, aside from diatomic molecules, what other molecules should I be aware of that are naturally different from the periodic table?

Answer 10

i know diatomic is h2, o2, n2, f2, cl2, br2, and i2

Answer 11

Answer 12

Umm I think those are the main ones, I can't think of any others

Answer 13

alright got it thanks
