Will someone please help me?? This is for chemistry module 6 DBA on Florida virtual.

1. You are traveling upward in a hot air balloon. Explain to me what changes as you go through each layer of the atmosphere. Mention things like temperature, pressure, adjustments you will have to make to survive, etc.
2. When discussing gasses, why do you have to include temperature, pressure, and volume of the sample?
3. Why do they say that steam burns are more dangerous than being burned by boiling water?
4. Why will it take longer to boil pasta on the top of a mountain than at sea level?
5. Helium is lighter than air. Explain the difference.
6. What is it usually warmer upstairs than downstairs?

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced
