It depends on a lot of factors. It varies from river to river.

Water vapor that contains chemical from air pollution?
Acid rain
Which agents bring about chemical weathering on rocks a.rainwater B.ocean water C.flowing water D. all of them?
rain water
Why is the chemical composition of a mineral important?
it means a naturally-occaring, inorganic solid that has a crystal structure and a definite chemical composition
Do rocks separate from water or does it dissolve?
Rocks,generally'seperate out from water,but,few may have infinitesimally low solubility in water.It depends on the chemical composition of the rock.
What is the precent composition of hydrogen in water?
The formula of water is H2O. The gram atomic mass of hydrogen is 1.008 and the gram atomic mass of oxygen is 15.999. Therefore, the mass percent composition of hydrogen in water is 100{(2)(1.008)/[(2)(1.008) + 15.999] or 11.19 %.The percent composition of hydrogen in water is: 11,19 %.
Chemical Weathering?
In chemical weathering, rocks are broken down, and their composition changes. Chemical weathering is caused by water, oxidation, carbon dioxide, organisms, and acid rain.
When water evaporates its chemical composition?
The chemical composition remain unchanged.
Does melting ice changes the chemical composition of water?
The chemical composition of water remain unchanged.
Why is it chemical when water is separated into o2 and h2?
It is a chemical change (reaction) because the chemical composition of the products (O2 and H2) is different from the chemical composition of the water (H2O).
Is water vapor condensing to form rain a physical or chemical change?
Condensation is a purely physical process (a change of phase). Water evaporating or condensing does not change its molecular composition (H2O).
What characteristics of water remains the same no matter what is dissolve in it?
The chemical composition of water remain constant.
What is water's element combination?
The chemical composition of water is H2O.
Is boliling water a chemical or physical change?
Boiling water is a physical change because it does not change the chemical composition of the water.
Why does the chemical composition of water always stay the same?
Because water is a compound, a type of pure substance, which has a definite composition.
Is mixing water with clay a chemical change?
No, it is a physical change because the chemical composition of the water or mud does not change.
Is water a chemcial?
It would depend on your definition of a chemical. A chemical is: "a substance produced by or used in a chemical process." And, water is a chemical because it is be used in chemical reactions such as neutralization, redox, etc. I believe what you're asking though is if water is a chemical substance: "a material with a definite chemical composition." Water is also a chemical composition because of its electron configuration in its valence shell which defines its chemical properties.
What is the chemical composition of the dwarf planet Ceres?
ice water.
