Why mercury weigh more than water?
13.7 times more. Because the atoms of mercury are heavier (more massive) than the molecules of water AND they're closer together.
Do faster atoms have more potential energy than slower atoms?
faster atoms have more kinetic energy than slower atoms do.
Is water made up of only one atom?
Water contains two kinds of atoms: 1 oxygen atom & 2 hydrogen atoms.
What is a pure subsatce whose smallest unit is made up of atoms of more than one element?
Compounds have atoms of more than one element.Covalent Compounds have covalent bonds between the atoms as in Water (H2O), or methane (CH4).Ionic Compounds have ionic bonds between the atoms such as Salt (NaCl) which will dissociate into ions in a suitable solvent such as water to give the ions Na+ and Cl-
How many times larger is the number of hydrogen atoms than oxygen atoms in water?
In a water molecule (H₂O), there are two hydrogen atoms for every one oxygen atom. This means that the number of hydrogen atoms is twice the number of oxygen atoms in water. Therefore, the number of hydrogen atoms is 2 times larger than the number of oxygen atoms.
Does gas atoms move more freely than water atoms?
Yes
Is there more atoms in a glass of water than there is people in the world?
A small 100 ml glass of water has something like 10^25 atoms in it. That number is greater than the number of people who have ever existed on the planet, past and present. In fact there are more atoms in a glass of water than there are grains of sand on the earth.
Why mercury weigh more than water?
13.7 times more. Because the atoms of mercury are heavier (more massive) than the molecules of water AND they're closer together.
Do faster atoms have more potential energy than slower atoms?
faster atoms have more kinetic energy than slower atoms do.
A substance that is made up of atoms of more than one element is a what?
compound
Is water made up of only one atom?
Water contains two kinds of atoms: 1 oxygen atom & 2 hydrogen atoms.
Is ammonia mlecule NH3 more polar than water molecule?
No, water molecule (H2O) is more polar than ammonia (NH3) because of the greater difference in electronegativity between oxygen and hydrogen atoms in water molecule compared to nitrogen and hydrogen atoms in ammonia molecule. Water has two polar covalent bonds while ammonia has only one.
How many atoms are in one living cell?
There are thousands of tiny atoms living in one cell. Because a cell is mostly made up of water, there are typically more water atoms than any other type of atom.
Why does aluminum float if pushed under water?
Because it is less dense than water. Basically, there is more space between atoms of aluminum than molecules of water, sort of like water and oil.
Is it true that in a water molecule the electrons within the molecule are attracted more towards the hydrogen atoms?
Water is a polar molecule where the electrons spend more time in orbitals around the oxygen atom because it is significantly more electronegative than the hydrogen atoms. So, false is the answer.
Does water have more hydrogen or oxygen in it?
By number of atoms it has more hydrogen, by mass it has more oxygen. Each water molecule contains two hydrogen atoms and one oxygen atom. However, a typical oxygen atom has about 16 times the mass of a typical hydrogen atom.
Why does sound travel fastest through air?
Air is less dense than say water. When you talk under water it is difficult to hear what is said because water has more atoms than air.
