Na + H2O = NaOH + H2
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

Let’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
------------------
ν - ?

Слайд 19

Let’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
------------------
ν - ?
