What are the 2 substances of water?
water, a substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states.
Is water made up of 2 compounds?
In summary, the modern definition of a compound is a type of molecule consisting of at least two different types of atoms. By this definition, water is both a molecule and a compound.
How do you make 2 water?
The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2).
What is H2O full name?
H2O is the molecular formula of water, also called Dihydrogen monoxide. H2O symbolises two hydrogen atoms and one oxygen atom.
Who named water?
The word water comes from Old English wæter, from Proto-Germanic *watar (source also of Old Saxon watar, Old Frisian wetir, Dutch water, Old High German wazzar, German Wasser, vatn, Gothic 𐍅𐌰𐍄𐍉 (wato), from Proto-Indo-European *wod-or, suffixed form of root *wed- (“water”; “wet”).

Will we ever run out of water?
While our planet as a whole may never run out of water, it’s important to remember that clean freshwater is not always available where and when humans need it. More than a billion people live without enough safe, clean water. Also, every drop of water that we use continues through the water cycle.
Can water be created by man?
Is it possible to make water? Theoretically, it is possible. You would need to combine two moles of hydrogen gas and one mole of oxygen gas to turn them into water. However, you need activation energy to join them together and start the reaction.
Can water be man made?
The answer: very. Just mixing hydrogen and oxygen together doesn’t make water – to join them together you need energy. If we can’t make water easily from its atoms, are there any other ways we can create it? Well, scientists are now focusing more on harvesting water from the air and using humidity to their advantage.
Why did Emma leave h20?

What is the chemical equation of water?
The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.

Is salt a solute in sea water?
Ocean water is a homogenous mixture of salt in water. It contains about 3 percent sodium chloride. Ocean water is the type of mixture called a solution, because the salt is dissolved in the water. Water is the solvent, and sodium chloride is the solute.
Is salt water a mixture?
Seawater is a mixture of many different substances. Some of these substances can be observed when the water in seawater evaporates and leaves behind salt. Water, H2O, is a pure substance, a compound made of hydrogen and oxygen.
Does Aqua mean water?

Is the 2 in H2O small?
H2O is the chemical formula of water. It means that each molecule of water is made up of two hydrogen atoms, indicated by the letter H, and a single oxygen atom, represented by the letter O. H20 is dihydrogen monoxide or simply water. The 2 is the subscript of H, which represents the presence of 2 Hydrogen atoms.
