dinitrogen pentoxide
N2O5
2
The subscript 2 shows the number of oxygen atoms in each molecule of the compound, carbon dioxide.
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
Not completely sure, but it's an ionic bond so I'm sure it would be lead (II) nitride
When the compound magnesium chlorate breaks apart into its separate components of Mg and ClO (subscript 3 on oxygen).
Subscript (:This is a subscript: (Na2) the "2" is the Subscript.
2
The subscript 2 shows the number of oxygen atoms in each molecule of the compound, carbon dioxide.
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.
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
The calcium salt should be Ca(ClO2)2, Calcium chlorite.
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.
Calcium oxide is; CaO. Results from Ca(2+) and O(2-)
this is magnesium sulfide MgS. Mg in group 2 with + charge and S in group 6 with 2- charge. so there is no subscript in this formula.
Not completely sure, but it's an ionic bond so I'm sure it would be lead (II) nitride
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 .
When the compound magnesium chlorate breaks apart into its separate components of Mg and ClO (subscript 3 on oxygen).
