The subscript "2" in the formula O₂ indicates that there are two oxygen atoms bonded together to form a molecule of oxygen. This notation is commonly used in chemistry to denote diatomic molecules, which consist of two atoms of the same element. In this case, O₂ represents the molecular form of oxygen that is essential for respiration in many living organisms.
What else can I help you with?
What term describes the 2 in the O2 oxygen gas formula?
It describes the di-atomic (di = 2) character of the oxygen molecule (O2) as found in gas. This indicates the build up of the oxygen molecule (O2) consting of two bonded oxygen atoms (O atoms)
What does the subscipt 2 indicate in the formula o2?
O2 meaning Oxygen, the subscript 2 means that oxygen generally doesn't run around as single atoms. Instead, oxygen pairs up, with each oxygen atom bonding with another to form a molecule.
How many atoms are in an oxygen molecule O2?
Molecules of oxygen exist in two relatively stable allotropes: breathable oxygen with the formula O2, and ozone with the formula O3. The little number indicates that these molecules are composed of (respectively) two or three oxygen atoms.
In a chemical formula what is used to indicate the number of atoms of each element?
It is called a subscript. For example: In the formula for water (H2O), 2 is the subscript indicating that there are 2 hydrogen atoms in the compound .
What does the subscript 2 indicate in the frmula O2?
The subscript 2 in the formula O₂ indicates that there are two oxygen atoms bonded together to form a molecule of oxygen. This notation is used in chemical formulas to specify the number of atoms of each element present in a compound. In this case, O₂ represents diatomic oxygen, which is the form of oxygen that is most commonly found in nature and is essential for respiration in many living organisms.
What does the subscript 2 indicate in the formula O2?
The subscript 2 indicates that there are two oxygen atoms bonded together in the molecule of oxygen gas (O2).
What are the di?
Diatomic elements consist of two atoms.The formula of these elements are always written with a subscript 2 in its symbol to indicate its molecular composition.examples: H2,O2.
What does the subscript 2 indicate in the formula?
there are two atoms in the molecule
What is the chemical formula for the oxygen we breathe?
The chemical formula for the oxygen in the air is O2, where the 2 should be a subscript.
What term describes the 2 in the O2 oxygen gas formula?
It describes the di-atomic (di = 2) character of the oxygen molecule (O2) as found in gas. This indicates the build up of the oxygen molecule (O2) consting of two bonded oxygen atoms (O atoms)
What does the subscipt 2 indicate in the formula o2?
O2 meaning Oxygen, the subscript 2 means that oxygen generally doesn't run around as single atoms. Instead, oxygen pairs up, with each oxygen atom bonding with another to form a molecule.
What is the formula of a molecule of oxygen?
The formula of an oxygen molecule is O2 (2 is a subscript but now WA doesn't permit to write a subscript).15.9994 g/mol is the molecular mass of oxygen. Formula mass is a sum of atomic mass of atoms in the molecule. In O2 there are two oxygen so it will be about 32g/mol
Does an oxygen molecule contain carbon?
No. Oxygen is an element and contains only oxygen atoms. Its formula is O2 (where the 2 is a subscript).
What is the chemical formula for Sr 2 and o2?
The chemical formula for strontium oxide is SrO. Strontium does not typically form a compound with a subscript of 2, so "Sr2" is not a common chemical formula. Oxgen typically exists as O2 gas in its elemental form.
What part of the chemical formula indicates the number of molecules or atoms involved?
The answer is 'subscript'
Why does the oxygen symbol O not have a subscript?
Because symbols for the elements do not have subscripts. A subscript is added in the chemical formula of a compound to indicate how many atoms of the element are included in a molecule of the compound. For example, when hydrogen (H) and oxygen (O) combine to form water (H2O), a subscript 2 is added to the H to indicate there are two hydrogen atoms in a molecule of water, but no subscript is added to the O, because there is only one oxygen atom is in a molecule of water.
How many atoms are in an oxygen molecule O2?
Molecules of oxygen exist in two relatively stable allotropes: breathable oxygen with the formula O2, and ozone with the formula O3. The little number indicates that these molecules are composed of (respectively) two or three oxygen atoms.
