Question

Sodium oxide reacts with water to make sodium hydroxide.

1. Write and balance the equation.
2. List all the mole ratios.
3. How many moles of water are needed to react with 18.4 moles of sodium oxide?
4. How many grams of sodium hydroxide are formed when 4.5 moles of sodium oxide react with excess water?
5. How many grams of water are needed to make 5.65 moles of sodium hydroxide?
6. How many grams of sodium hydroxide are formed when 23.7 g of sodium oxide react with excess water?
7. How many liters of water are required to form 93.4 g of sodium hydroxide?

Answer 1

So the total mass is 50 plus 150 grams the heat capacity 4.18 joules per gram per degree C. And the temperature change is 36 minus 25 and so we can calculate Delta H for the reaction that takes place.
