What is the number 2 in the formula for hydrogen called?
H2O The little 2 is a subscript that tells you that there are 2 Hydrogen atoms in the compound. There is no 1 after the Oxygen because if there is no subscript, there is an understood 1 atom in the compound.
How many atoms of Hydrogen are present in a water molecule?
It is common knowledge that the chemical formula for water is H2O. In chemical formulae, subscripts apply to the letters that they go after. So there are 2 Hydrogens in a single water molecules.
What is the formula for lithium hydrogen phosphate.?
The formula for lithium hydrogen phosphate is Li2HPO4.
What is the molecular formula of paracetamol?
The formula for acetaminophen, otherwise known as paracetamol, is C8H9NO2
What does subscript indicate in a chemical formula?
The number of atoms of the same element in the molecule
The number placed below an elements symbol in a chemical formula is called a what?
The number placed below an element's symbol in a chemical formula is called a subscript. Subscripts indicate the number of atoms of that element in a molecule.
What does a subscript in a chemical formula represents?
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
What part of the chemical formula indicates the number of molecules or atoms involved?
The answer is 'subscript'
What do the subscript numbers represent in a chemical formula?
They tell you how often an atom - or a group of atoms - are repeated.
Which number is not written in subscript in a chemical formula?
The number representing the charge in an ion is not written in subscript in a chemical formula.
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 .
Examples of a chemical formula?
subscript
what number represents the subscript in the formula shown?
The letter or letters that represent an element are called its atomic symbol. The numbers appearing as subscripts in the chemical formula indicate the number of atoms of the element immediately before the subscript. If no subscript appears, one atom of that element is present.
What does the subscript 2 indicate in the formula?
there are two atoms in the molecule
What does the subscription indicate in the chemical formula co2?
The 2 indicates that there are 2 oxygen atoms.
Do you have to use subscript in chemical formulas?
Not every chemical formula requires subscript. For example table salt is NaCl, sodium chloride. No subscript. But most chemical formulae do require subscript, such as water, H2O.
