Here are some rules:
1. The oxidation state of a free element (uncombined element) is zero.2. For a simple (monatomic) ion, the oxidation state is equal to the net charge on the ion.3. Hydrogen has an oxidation state of +1 and oxygen has an oxidation state of −2 when they are present in most compounds.
The oxidation number of Fe in Fe(NO3)2 is +3.
country of origin and chemical makeup
Hydro- meaning Hydrogen.
Carbon- meaning Carbon.
Hydrogen and Carbon. Carbon atoms form the framework, and Hydrogen atoms attach to them in many different configurations.
Hope this helps!
Answer:
You can identify an unknown substance by measuring its density and comparing your result to a list of known densities. Density = mass/volume. . You divide the mass by the volume and compare the density to a list of known densities.
I think its because an egg doesnt have the right chemical make up
