Is HNNH an element compound or mixture?
HNNH is a compound. It is the chemical formula for hydrazoic acid, which is a compound composed of hydrogen, nitrogen, and a small amount of carbon.
In a small amount of a compound there may be what of molecules?
In a small amount of a compound, there may be billions to trillions of molecules, depending on the molecular weight of the compound. This number is determined by Avogadro’s number, which is a fundamental constant used to relate the number of particles to the amount of substance.
What does the small number after the O represent in the chemical equation?
I guess you mean the number "2" in O2. It is the valency of oxygen which means oxygen can have two single bond (hydrogens) with two other elements or a single double bond with an element. A good example methane-CH4, here single carbon atom paired with four hydrogens with four single bonds.
What is the chemical combination of symbols that represents a compound?
Each element is given a symbol (a letter or a pair of letters where the first one is always a capitol letter and the second one is always a small letter). For instance the letter for Hydrogen is an 'H' and for Oxygen is an 'O'. When describing the formula for a chemical compound you use these symbols to say what elements it is made of and you follow each element with a number if there is more than one atom of that element in the compound. For instance water is made of one atom of Oxygen and two atoms of Hydrogen and therefore its chemical formula is: H2O
What does a subscript show in a chemical formula?
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
What do subscripts represent?
Subscripts represent the number of atoms of an element in a molecule. They are written as small numbers to the right of the element symbol in a chemical formula. They indicate the ratio of elements in a compound.
The small number used to represent the number of ions of a given element in a chemical formula?
The small number used to represent the number of ions of a given element in a chemical formula is called a subscript. Subscripts are written to the right of the element's symbol and indicate the number of atoms or ions present.
Is HNNH an element compound or mixture?
HNNH is a compound. It is the chemical formula for hydrazoic acid, which is a compound composed of hydrogen, nitrogen, and a small amount of carbon.
Is NO a element or compound?
Nitric oxide or nitrogen monoxide (NO) is a compound made up of one nitrogen and one oxygen atom per molecule. A compound consists of two or more elements that are chemically combined. For elements with chemical symbols of two letters, the first alphabet would be in capital and the second alphabet would be in small letter.
What represents the actual number of atoms present in a compound?
The subscript (The small number at the bottom). Like SnO2. It shows that Sn is one atom together, and the O has 2.

Is carbon dioxde a compound?
Yes, Carbon Dioxide is a Compound its symbol is CO2 (Note Number is meant to be small)

What does a subscript show in a chemical formula?
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
Where does a subscript belong in a chemical formula?
A subscript belongs immediately after the symbol of an element in a chemical formula to indicate the number of atoms of that element present in the compound. It is written as a small number at the bottom right of the element's symbol.
What does the small number at the bottom corner of a number mean?
This is called a subscript, and is often used in chemical formulas. For example, C6 is 6 carbon atoms, and O2 is two oxygen atoms.
