What else can I help you with?
Are there molecules in oxygen?
No, Oxygen is an atom, and as such is composed of protons, neutrons and electrons. There are no molecules in oxygen, but a single oxygen atom becomes a molecule when it is combined with another oxygen atom to form O2.
When elements combine to make a compound is it always in the same proportion?
No, the elements are not always in the same proportion. For example, two atoms of hydrogen combine with one atom of oxygen to make a single molecule of water. But one atom of hydrogen combines with one atom of fluorine to make a single molecule of hydrogen fluoride. The numbers of atoms involved depends on the number of electrons available in the outer electron clouds of the atoms involved.
Do iodine and iodine combine toghether?
Iodine molecules can combine with each other to form diatomic molecules, which is the typical form of elemental iodine found in nature. Each iodine atom contributes one electron to form a single covalent bond that holds the two atoms together.
How do single celled organisms get oxygen?
Single-celled organisms typically absorb oxygen directly from their environment through a process known as diffusion. Oxygen molecules move from areas of high concentration to low concentration, allowing these organisms to take in oxygen from their surroundings to support their metabolic processes.
Difference between 2O and 2 O in a chemical equation?
In a chemical equation, 2O represents two oxygen atoms whereas 2 O represents two oxygen molecules. Oxygen atoms are single atoms of oxygen, while oxygen molecules consist of two oxygen atoms bonded together.
How many molecules are in the ozone?
There are three molecules in ozone. It can be man made from oxygen, with a high voltage electrical discharge, that splits the oxygen from two molecules into three which gives you ozone.
Why does it take several redox reactions in a cell to make water from hydrogen?
Hydrogen and oxygen combine explosively in a single reaction.
Is the are you breath a single compound?
No. Air always contains two elements, oxygen and nitrogen, neither of which is a compound, although they occur as diatomic molecules.
What are the 3 atoms of ozone molecules?
There are more than three. There is nitrogen (N2), oxygen (O2), and argon (Ar) as the biggest three. And ozone (O3) is a peak of about 9 ppm.
What is formed when two or more substances combine?
Its a chemical change, and the simplest is when two atoms combine to from a compound. When there is a single oxygen atom, it is called ozone, then two combine in an ionic bond, they are an oxygen molecule.
Why does it take several redox reactions in a cell to make hydrogen and oxygen?
Hydrogen and oxygen combine explosively in a single reaction.
What are oxygen molecules?
more than one oxygen atom joined together by single covalent bonds
Are all molecules made from a single atom?
No, Water is a molecule with hydrogen and oxygen
What is monotonously?
Always the same.
Atmospheric oxygen contains how many atoms per molecule?
Atmospheric oxygen contains three oxygen atoms per molecule. This is known as ozone and is formed in the upper part of the atmosphere by solar rays. O2 molecules are split apart by the energy of solar rays. Then single oxygen atoms bond with oxygen molecules to form O3 molecules. UV radiation from the sun also dissociates O3 molecules back into single O and O2.
What is the molecular formula for nitrogen oxygen carbon and hydrogen?
Nitrogen, oxygen, carbon and hydrogen are elements that combine to form molecules in a vast number of ways. There is no single molecular formula for them. The symbols for these elements are: nitrogen: N oxygen: O carbon: C hydrogen: H
What are some elements with a single atom that cannot be combined?
When atoms combine to make molecules only the electrons adhere together to form bonds. The protons, neutrons, and nucleus do not combine.
