All pure water is the same, but most water we use has other things in it. For example mineral water has minerals.

Does water have a definite chemical composition?
Yes it does. There are eight grand of oxygen for every gram of hydrogen.
Is water a molecule or mixture or compound?
it is a compound............. as it is made up of proper composition of hydrogen and oxygen
What is the physical composition of water?
Physical characteristics of water are temperature, colour, turbidity, odor and taste, and solid content.
Why water is called a compound and air a mixture?
Compound have constant composition whereas mixture have variable. Now, water made by constant composition of hydrogen and oxygen (two atoms of hydrogen and one atom of oxygen) whereas air have many elements with variable composition.
What elements are found in both carbohydrates and water?
Water contains hydrogen and oxygen. Sugar contains carbon, hydrogen and oxygen.
Do all samples of water have the same composition of hydrogen and oxygen?
Yes, otherwise it wouldn't be water.
What is the molecular composition of water?
H20 is the molecular composition of water. Two hydrogen atoms and one oxygen atom. The hydrogen atoms are pulled to the oxygen atom through forces called hydrogen bonding.
How does the composition a mixture of hydrogen differ from the compound containing hydrogen and oxygen?
The compound is water - H2O; the molecule of hydrogen is H2.
How does the composition of a mixture of hydrogen and oxygen differ from the composition containing hydrogen and oxygen?
A mixture of hydrogen and oxygen would consist of separate H2 and O2 molecules. The hydrogen and oxygen would retain their own properties. The most common compound of hydrogen and oxygen is water. In it the two elements are combined into molecules of H2O, which has its own set of properties distinct from those of hydrogen or oxygen.
What is the chemical composition WATER?
2 hydrogen molecules, 1 oxygen molecule (H2O)
Is being composed of hydrogen and oxygen a physical property of water?
Yes, being composed of hydrogen and oxygen is a physical property of water. Physical properties refer to characteristics that can be observed or measured without changing the composition or identity of a substance, and the specific arrangement of hydrogen and oxygen atoms in water molecules is a defining physical property of water.
What characteristics of water remains the same no matter what is dissolve in it?
The chemical composition of water remain constant.
Does water have a definite chemical composition?
Yes it does. There are eight grand of oxygen for every gram of hydrogen.
Is water a molecule or mixture or compound?
it is a compound............. as it is made up of proper composition of hydrogen and oxygen
Do solutions have a definite composition?
Definite proportions, not indefinite proportions. What it says is that the composition of a compound is the same regardless of its state. For instance: Water is 11.1% hydrogen and 88.9% oxygen by mass. If I were to freeze water into ice, its composition would be 11.1% hydrogen and 88.9% oxygen by mass. If I were to vaporize the water into steam, its composition would be 11.1% hydrogen and 88.9% oxygen by mass. If I were to take ice, melt it, use an electrical current to electrolyze it into hydrogen gas and oxygen gas, burn them together to form water, flash freeze the resulting water to a temperature of -200 oC, it would still have a composition that is 11.1% hydrogen and 88.9% oxygen by mass. That is what the law of definite proportions tells you.

What is the composition of water?
Water (H2O)Water is composed of two parts hydrogen and one part oxygen. We know this because hydrogen (H) has a 2 after it, meaning there are two parts hydrogen in the substance. Then after the hydrogen symbols, we see oxygen (O) without any numbers after it - meaning there is only one part oxygen in the mix.H2O - 2 x Hydrogen and 1 x Oxygen
