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.
How does storing water in reservoirs help to purify water?
Water is stored in a reservoir until needed. While stored, particles of dirt settle at the bottom. This helps to purify the water.
What is the atomic number of saltwater?
Atomic numbers are only assigned to elements, so only things on the periodic table. Saltwater is a mixture
What is the valency of Sodium in Na2Co3?
0The valence of Na in this compound is +1 and of Carbonate it is -2However it is better to use: ionic charge or -number,So, when dissolved in water, you get:Na2CO3 -> 2 Na+ + CO32-
What elements are in muddy water?
Mud and Water
Is kg an independent variable?
No, a Kilogram (Kg) is not an independent variable. An independent variable is any system that remains free from change If something else changes. We would therefore say a Kilogram is a dependent variable. The amount of Kilograms depends on the amount of fat, water, organs, etc stored.

How is water stored in the atmosphere?
Water is stored in the atmosphere in the form of water vapor.
How much water is in an orange the variable?
Your variable in the 'How Much Water is in an Orange' experiment will be- Independent variable: The amount of water in the orange. Why? Because this is what you physically changed. Dependent variable: The weight of the dried orange. Why? Because this is what happened after you removed the water.
What is a dependnent variable?
A dependent variable depends on the independent variable. If you are doing an experiment about how temperature affects the heat of water then the independent variable would be the temperature, as that is what you are going to change, and the dependent variable the water as the temperature of the water depends on the temperature surrounding it.
Where do you find water stored as a gas?
In the atmosphere stored as water vapor
What are the dependent and independent variable in what is the water cycle?
independent variable is the water i dont know
Where is most of earths water stored?
Most water is stored in the oceans. However, the most freshwater is stored in glaciers. To the person whose answer I'm editing, a reservoir is anything that holds water, so of course that's where water's stored.
Where is most water stored in the water cycle?
Water is mainly stored inside bodies of water such as lakes, rivers, streams, and oceans. It can also be stored in plants and other vegetation.
