Homework Help: Chemistry

1. Hydrogen and oxygen gas combine explosively to produce water. Write a balanced chemical equation for this process. If 10 mol of hydrogen reacted with oxygen, what volume of liquid water could be produced?

2. You sometimes hear in a medical show on TV something like “Give the patient 200 cc’s of medicine X”.
Given that a litre is a cubic decimetre, and that a cc is short for cubic centimetre, show that a cc is also a millilitre.

3. A label on a soft drink bottle indicates that it contains 10% sugar w/vol. This means the sugar concentration is 10 g/100 ml. Given a teaspoon of sugar weighs 4 g, calculate how many teaspoons of sugar you would consume if you drank a 600 ml bottle of the soft drink.

The rest i managed to complete but its just these three that I am having a difficult time with :/ Thank you

2H2 + O2 ==> 2H2O

10 mols H2 x (2 mol H2O/2 mols H2) = 10 mols H2O produced.
