What can you do to prove water is a compound of hydrogen and oxygen?
water is a compound because it does not show its constituent's properties and has fixed proportion by mass,,,,,,,,,,,,,,,,
How one has more molecules 9g of water or9g of sugar?
Perhaps you mean: Does sugar have more atoms than water?In a certain fixed mass of sugar/water, there will be more molecules of water than of sugar since the molecular mass of sugar is higher than that of water. We follow the rule of Mass = Number of moles of a substance * Molecular mass of the substance.We rearrange this to form Number of moles = Mass / Molecular massTherefore, since the molecular mass of sugar is higher, the number of moles of sugar in a fixed mass of sugar is lower. The number of moles of sugar is directly proportional to the number of molecules of sugar, since we follow Avogadro's Law:1 mole = 6 * 10^23 molecules (constant value)However, if you meant to ask if sugar had more atoms than water, the answer is yes, it does. Sugar (presumably glucose) has the chemical formula of C6H12O6 and thus has 24 C, H and O atoms altogether. Water, with the formula H2O, has 3 atoms of H and O altogether.I hope this was helpful! :)
The elements in a are always combined in the same proportion by mass?
From many years this affirmation is not considered valid.
When sugar is dissolve in water and the water is evaporated off the mass of the sugar does what?
The mass of the sugar remains the same.

The mass of a pill is not a fixed amount.The mass of a pill is not a fixed amount.The mass of a pill is not a fixed amount.The mass of a pill is not a fixed amount.
What substance that contains 2 or more elements chemically combined in a fixed proportion?
A substance made of two or more elements chemically combined in a specific proportion is called a compound. A substance composed of two or more elements combined chemically in a fixed proportion by mass is called a compound. A chemical compound can be held together by a covalent bond or an ionic bond.

No.
Does a liquid have a fixed mass under conditions?
The mass of a given volume of a liquid is fixed.

Theory that the continents were once joined joined as one large single land mass?
The theory of continental drift is about the continents were once joined joined as one large single land mass.
