Reasons to say water is a compound; (1) water is made up of 2 elements in a fixed ratio. Depending on temperature and other factors, water is present on different parts of earth’s surface and at different times as a liquid.
A Gas Remains A Gas Even When Pressure Is Applied.
The true pure water (h2o) is a compound because the constituents are bond chemically in a certain fixed proportion. (4) water has totally different properties from 2 elements. (5) it has a fixed boiling point.
Saltwater Can Be Separated Or Broken Down Into Compounds.
Water, h2o, is a natural substance, a compound made of hydrogen and oxygen. A glass of pure water is a mixture of h 2 o molecules and other compounds. (2) its constituents can be separated only by chemical or electrochemical reactions.
What The Industry Consider As Pure Water Is Generally A Water That Has Experienced Mechanical.
1 the elements of water hydrogen and oxygen are in a definite proposition by weight 1;8 : If you break down the chemical formula of water, each molecule contains one atom of oxygen bonded to two atoms of hydrogen. Water is the solvent, and salt is the solute that dissolves.
An Example Of A Compound Would Be Table Salt, Nacl.
Compound is a pure substance which is composed of two or more elements in a definite proposition by weight.: 2.the composition of water is by chemical reaction between two pure elements hydrogen and oxygen in a fixed ratio and can only be broken down by chemical reaction. Is tap water a mixture?
Although Water Is The Most Considerable Substance On Earth, It Is Hardly Discovered Naturally In Its Pure Form.
H2o is not a mixture because a mixture doesn’t have a definite ratio of composition. It’s formed when hydrogen atoms bond with oxygen atom. A compound is formed when two or more elements bond chemically in a fixed ratio by mass.
