What is true of every water molecule?

What is true of every water molecule?

Every water molecule is made of two hydrogen atoms and one oxygen atom. 2. Water molecule is composed of two light hydrogen atoms that are joined to a 16-fold heavier oxygen atom.

Is it true that water is composed of more than two elements?

If it were made up of more than one kind of atom, it would be a compound. Water is a compound because it is made up of water molecules. There is no such thing as water atoms. Water molecules are made of hydrogen and oxygen atoms, in the definite proportion of two hydrogens for one oxygen.

Is water made up of 2 atoms?

To find out what water is made of, it helps to look at its chemical formula, which is H2O. This basically tells us that the water molecule is composed of two elements: hydrogen and oxygen or, more precisely, two hydrogen atoms (H2) and one oxygen atom (O). Hydrogen and oxygen are gases at room temperature.

What is true of every water molecule Brainly?

Answer Expert Verified Every water molecule is made of two hydrogen atoms and one oxygen atom. Water molecule is neutral electrically but polar because of its polar covalent bonds and its bent nature. Water exists in liquid form, in solid form as ice, and in gaseous form as water vapor or steam.

What is a water molecule made of Brainly?

Answer Expert Verified It is made of 2 hydrogen molecules and 1 oxygen molecule.

What feature makes water a polar molecule?

A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons.

Is C soluble in water?

The water-soluble vitamins include ascorbic acid (vitamin C), thiamin, riboflavin, niacin, vitamin B6 (pyridoxine, pyridoxal, and pyridoxamine), folacin, vitamin B12, biotin, and pantothenic acid.

Is water made up of 2 atoms?

The water molecule is composed of two hydrogen atoms, each linked by a single chemical bond to an oxygen atom. A water molecule is made up of two hydrogen atoms and one oxygen atom. A single oxygen atom contains six electrons in its outer shell, which can hold a total of eight electrons.
