To clear up any confusion: water is not a mixture of hydrogen and oxygen; it is a compound. The hydrogen and oxygen are chemically bonded to each other to form a completely different substance.
There are two reasons for the difference in density. First, molecules of elemental hydrogen are only weakly attracted to one another, so hydrogen exists as a gas with a lot of space between molecules. Water molecules are very strongly attracted to one another and so water exists as a liquid with much less space between molecules. Second, a water molecule contains two hydrogen atoms and one oxygen atom. One oxygen atom has about 16 times the mass of a hydrogen atom, so most of the mass of water is actually oxygen. One water molecule is about 9 times the mass of a hydrogen molecule.
What else can I help you with?
Is water or salt water heavier?
Salt water is heavier than fresh water. The salt dissolved in salt water increases its density, making it heavier than pure water.
What substance has more hydrogen ions than pure water?
an acid has more hydrogen ions than water.
Which is heavier hydrogen or helium?
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
How many times heavier than hydrogen atoms of Carbon and Calcium?
A carbon atom is about 12 times heavier than a hydrogen atom, while a calcium atom is about 40 times heavier than a hydrogen atom. Therefore, carbon atoms are 12 times heavier than hydrogen atoms, and calcium atoms are 40 times heavier than hydrogen atoms.
What elements are heavier than hydrogen?
All of them. There are no elements lighter than hydrogen. It has only two atomic particles, and you cannot have an element with less.
Is salt water's density heavier than pure water?
Salt water's density greater (not heavier) than that of pure water.
Is water or salt water heavier?
Salt water is heavier than fresh water. The salt dissolved in salt water increases its density, making it heavier than pure water.
Is frozen salt water heavier than frozen water?
The density of saline water is greater than the density of pure water.
What substance has more hydrogen ions than pure water?
an acid has more hydrogen ions than water.
What gas is heavier hydrogen or oxygen?
oxygen gas is heavier than hydrogen gas
Is Seawater is typically denser than freshwater due to seawaters?
Salt
Why is water heavier than the two gasses that compose it?
fluids are heavier than gases. When hydrogen its by itself is lighter than water as so the oxygen is also lighter. Once combined they form a fluid thus the combination of two gases produced a fluid which will turn heavier.
Is Saturn lighter or heavier than water?
Saturn is much lighter than water. It is a gas giant made primarily of hydrogen and helium, with a density lower than that of water.
Which is heavier hydrogen or helium?
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
What is lighter than helium but heavier than air?
hydrogen
How is light water light different than heavy water?
Heavy water is heavier than light water because instead of both hydrogen atoms in the molecule being ordinary light hydrogen (H - one proton) one or both hydrogen atoms are heavy hydrogen (D - one proton, one neutron).
How many times heavier than hydrogen atoms of Carbon and Calcium?
A carbon atom is about 12 times heavier than a hydrogen atom, while a calcium atom is about 40 times heavier than a hydrogen atom. Therefore, carbon atoms are 12 times heavier than hydrogen atoms, and calcium atoms are 40 times heavier than hydrogen atoms.
