How to write the formula for calcium chloride. Explain how you determined this formula?
Calcium's chemical symbol is Ca. Calcium's oxidation number is +2.Chloride's chemical symbol is Cl. Chloride's oxidation number is -1.Ca +2 Cl -1Ca 1 Cl 2 (Switch the two numbers)Ca1Cl2 HOWEVER if there's only one of an element, don't write the 1CaCl2
How are chemical formulas written do they use superscripts or subscripts?
Chemical formulas are written with the chemical symbol of each element followed by a subscript. If no subscript is written, it is understood to be 1. In a molecular formula, the subscripts indicate the number of atoms of each element that are present in one molecule. In a chemical formula for an ionic compound, the subscripts represent the lowest whole number ratio of ions in the compound.
What are two things that are shown by a chemical formula?
Scientist combine the symbols for different elements when they write chemical formulas.
A chemical formula is an expression used to represent?
Chemical formulas are a shorthand way to represent chemical compounds. For example, CO2 is quicker to write than carbon dioxide.
How do I write chemical formula for Iron sulfate?
The chemical formula for iron sulphate is dependent on the oxidation state of iron. For iron '2', it is FeSO4 For iron '3' , it is Fe2(SO4)3
Use oxidation numbers and their least common multiples to write what?
Formulas for compounds
What do you use oxidation numbers and their least common multiples to write?
They are used to write balanced chemical equations.
What are the Stock system names for the following compounds?
The Stock system is the current system to write chemical formulas; oxidation states are in parentheses, with Roman numerals.

What is the purpose of assigning a symbol to represent each element?
It makes it easier to write out chemical formulas for compounds.

What compounds can be formed from element X with oxidation number 3 plus and 5 plus and element Z with oxidation numbers 2 and 3 write their formulas?
X(3+) and Z(2-) will give X2Z3. X(3+) and Z(3-) will give XZ. X(5+) and Z(2-) will give X2Z5. X(5+) and Z(3-) will give X3Z5.
What is the chemical symbol for nickelII?
Nickel(II) is the plus two (+2) oxidation state of nickel (Ni), and we write it Ni(II) or Ni++ when we set it down.
