How did the following gases (Carbon dioxide, Water, Nitrogen) change during these times:

1. The Early Earth had no atmosphere or ocean.
2. Then volcanic gases and comets vaporizing on impact with the Earth released gases that became the atmosphere.
3. Originally, the atmosphere was hot and all water was in the form of water vapor.
4. Then, as the Earth cooled, water vapor condensed and fell as rain, covering the Earth in one big ocean until continents formed.

then there was the first ice age because earth couldnt get exposed to sun. after another million years or so when earth started to get exposed to sun because the dust and smoke and vapours cleared, the ice slowly started to melt. but during that time for the first time there was chemical reaction so hydrozen started to get separated fro oxyzen. so the oxygen was released in the atmosphere.

Carbon dioxide is dissolved in water with the total pressure of gas (Carbon dioxide + water vapor) over the water being 2.60 atm. The temperature is 25o C. What is the concentration of Carbon dioxide in the water?
Give your answer in g/L .
The vapor pressure of water at 25.0oC is 23.8 mm Hg.

NOTE! The Henry's Law's constant given in some of your texts for CO2 is for units of atm. The correct value for mm Hg is 4.45 × 10−5 mol/L/mm Hg This is value you should use in your calculation.

Although I spent forever in the CAPA center I'll help you out I wont do the calculations but I'll set them up for you.

1) convert 2.60 atm to mmHg
Do this by
2.80atm x 760 mmHg = answer a

2) Find the Pressure of O2 do this by taking
answer a - 23.8mmHG (given) = answer b

3) The equation for this problem is Sg = Kh x Pg

sg = answer a x 4.45 x 10^ -5 (given) = answer c

4) They ask for the units in g/l right now you have mol/l
so convert it to mol/l you should already know that equation :)

What type of food do plants make from carbon dioxide, water and sunlight?

Using the items mentioned in the question , namely, Carbon dioxide, water and Sunlight ; plants make GLUCOSE.

It is a carbohydrate that is soluble in water .

It is used as an immediate energy source or converted in to starch for storage .

All other organic molecules such as lipids , proteins etc. are directly or indirectly derived from this simplest of all sugars.

Sun light is the energy source and other two are the raw material and Oxygen is the byproduct .

Are carbon-based life-forms that use water the only possible or probable types of living things?

only carbon based so far. the main reason is that they are able to form four bonds and able to undergo millions of different types of reactions.

below carbon is silica, which has some similar bonding properties as carbon, but no animals use silica as a biological building backbone.

all living things contain carbon, hydrogen, oxygen, nitrogen, as well as salts NaCl, MgCl2, and metals Fe, Zn, Cu and other nonmetals like S, P. mammals contain a lot more than just Carbon and water

The word carbohydrate is deprived from carbon and water(hydrate). Explain why this combination correctly describes the chemical group.

the chemical formula for a carbohydrate is C6 H12 O6
you have your 6 carbons (the carbo-) and you have 6 water molules (-hydrate). H12O6 means that for every one oxygen there is two hydrogens, which is the set up of a water molecule.
C+C+C+C+C+C+H2O+H2O+H2O+H2O+H2O+H2O
=C6 H12 O6
