All liquid contains small amounts of dissolved gases in it. water that we drink at room pressure and temperature contains small amounts of nitrogen, oxygen, carbon dioxide etc. Lemonade will then contain these dissolved gases too. Also, in a closed system (such as in a bottle) some of the lemonade will have evapourated, and it will then be present in the vapour phase of the closed system. Lemonade also contains small bits of solid cells obtained from the lemon from which it was made. three states: vapour (evapourated lemonade, and gas present in the lemonade), liquid (the water in the lemonade) and solid (cells and other bits in the lemonade).
Yes, of course: There is one oxygen atom in every molecule of water!
there is no oxygen present in the electron transport system.
there is no oxygen present in the electron transport system.
Yes Oxygen is present in other planets.
Turn out that it is not present (OXYGEN in fossil fuels).
Oxygen is present because you can breath it, and it is all around us, but you can not see it. So in some cases it isn't present, but in most it is present.
4 oxygen atoms are present
no there is not
No .
Glycolysis
Place a glowing splint into the test tube. If the glowing splint relights, then oxygen is present, otherwise oxygen is not present.
