Why must oxidation numbers be assigned to the elements before writing a chemical formula?
The oxidation numbers of the elements in a chemical formula, some of which will be positive and others of which will be negative, when multiplied by the numbers of atoms with each oxidation number, must produce products that add to a net result of zero.
What role do oxidation numbers play in a chemical formulas?
Oxidation numbers are very important in much of chemistry because many times atoms do lose or gain electrons. When this happens, they become ions.However, oxidation numbers are especially important when writing chemical formulas for ionic compounds.
When writing chemical formulas do you add superscripts so that the sum of the oxidation numbers equal?
zero, it equals zero
What is the oxidation numbers in PO34?
The oxidation numbers in PO43- , phosphorus oxidation number=+5; oxygen = -2
What is the sum of the oxidation numbers for P2O5?
There are two oxidation numbers. P shows +5 oxidation number.

What is an oxidation number and how does an atom get one?
Before involving any chemical reactions or bonds, an atom has an oxidation number of zero. Accepting electrons will lower the oxidation number to negative numbers. Discharging electrons such as metals will result in positive oxidation numbers.
Is oxidation mechanical or chemical weathering?
Oxidation is chemical weathering.
What do you use oxidation numbers and their least common multiples to write?
They are used to write balanced chemical equations.
Is oxidation of food in the body chemical change?
All oxidation is a chemical reaction.
What is the process causing rocks to change composition when reacting with oxygen?
oxidation
What is ionic?
Ionic equations are a special type of chemical equations that demonstrate the changes in oxidation numbers in particular ions.
When writing chemical formulas do you add superscripts so that the sum of the oxidation numbers equal?
zero, it equals zero

Is oxidation a physical change?
Oxidation and reduction are chemical changes.
