According to the textbooks, nothing.Gold is very inert, and wont even react with dilute acids.
the sand dissolves in the water
Water and oxygen
Since water and carbon dioxide are both compounds which contain oxygen, it is possible to obtain oxygen from either, but you get a different residue depending upon which compound is the source of the oxygen. Take the oxygen out of water and you are left with hydrogen gas; take the oxygen out of carbon dioxide and you are left with carbon, which is a black solid. It is easy to spot the difference between hydrogen and carbon.
It will separate and the oil will float to the top, as it is lighter than water.
The suger gets left behind while the water evapourates
water is left
The oxygen atoms left behind from the water molecules join into diatomic oxygen molecules.
no, nothing happens to the chemistry of the water. it still stays 2 pars oxygen 1 part hydrogen
As the water is poured into the glass, some oxygen dissolves in it. If the water doesn't move, the oxygen slowly diffuses out of it. If you were to pour in the water in a vacuum and then removed the vacuum and left the water stagnant, there would be no oxygen content decrease.
When gold chains are left in bleach they begin to deteriorate. This is because bleach is a very heavy base.
No cause gold doesn't rust at al!!!
its hamless
the sand dissolves in the water
If it is left for some time as the water will oxygenate and the oxygen is what causes rusting.
Water and oxygen
Oxygen is a big "left over".
If the water is left outside in an open container it eventually will evaporate. If left outside during cold weather it could freeze.
