Want this question answered?
You can't tell just from the temp - cool water is capable of dissolving more oxygen ... but that doesn't mean that it will (or does).
The element "h2o" is water. It was one hydrogen atom and two oxygen atoms. This is completely backwards. The "2" means 2 hydrogens and ONE oxygen. Another term for water is Di-hydrogen-oxide. Di = Two > Hydrogen = Hydrogen [duh] > Oxide = Oxygen
Density depends on salinity to tell how dense something is so if you had a cup of salty water and a cup of not salty water, then the salty water would be denser than the cup of not salty water.
In 1 mole of water, the total amount of oxygen is only 16g. But the amount of the same in 1mole of Hydrogen peroxide is 32g. So more oxygen is present in hydrogen peroxide than in water.
Yes, please tell me how I can do that!!

Can help me about that ''How can you tell that something from the tea leaves has dissolved in the water ''
the amount of salt dissolved in the water
Because they are not there anyone or the water has gone a cloudy and you cant see through it.

This question does not make sense i does not tell us what has been disolved in the water so we cannot find the answer

Water is H2O, so it contains two hydrogen atoms (H2) and one oxygen atom (O).
save the water stop the earth from getting hotter

You can't see it.
