Hello!
Can somebody help to figure out this pls?
Sodium reacts in water to form sodium hydroxide and hydrogen gas. Write a balanced equation for this reaction and calculate how many grams of it are needed to prepare 8 g of sodium hydroxide by this method.
Ar(H)=1 Ar(O)=16 Ar(Na)=23
Balanced equation:
2 Na + 2 H2O --- 2 NaOH + H2
Sodium hydroxide mass: 40 g
I could easily figure out the balanced equation, but I don't know how to do the rest.
Thx!
