Sodium plus h two o yields N a O H plus H two

Let’s balance this one:

We have one sodium, two hydrogens and one oxygen in left part.
And still one sodium, one oxygen, but 3 hydrogens.

So, the coefficients are:
2Na + 2H2O = 2NaOH + H2

Слайд 18Let’s try to solve chemical problem in English.

Problem: Convert 20

grams of H2O to moles.
Problems
To get moles of H2O we

need…

Task
mh2o = 20 g

Слайд 19Let’s try to solve chemical problem in English.

Problem: Convert 20

grams of H2O to moles.
Problems
To get moles of H2O we

need divide mass (grams) by molar mass:
Moral mass of water is 18 grams per mole.

ν = mh2o/18 = 20/18 = 10/9 = 1.1 mol

Task
mh2o = 20 g
