Is it true that non metal oxides which react with water to form acids are called acidic oxides?
non metal oxides react with water to give oxyacid but also do undergo disproponation depending on the oxidation number ( oxidation number is increased and decreased, respectively) of the metal N2O5 + H2O → 2HNO3 3NO2 + H2O → 2HNO3 + NO
What is true about the sum of all oxidation numbers?
For a neutral molecule it is zero, for polyatomic ions the sum is the same as the ionic charge.
Is it true that in ionic compounds the oxidation number is the same as the charge on the ion . a neutral ionic compound can only contain ions with identical charges?
No, it is not true that a neutral ionic compound can only contain ions with identical charges. You can have, for example, a compound that consists of twice as many positive ions as negative ions, but the positive ions have only half the charge; +1 ions bonded to -2 ions. There are many different possible ratios with which different elements or radicals combine. As long as the total amount of charge adds up to zero, you still have a neutral ionic compound.
An ionic compound is made of a nonmetal and a metal true or false?
It is true of binary ionic compounds but not necessarily of compounds containing polyatomic ions.
What is the oxidation state of nitrogen in the molecule N2?
The oxidation state (or number) is zero. This is true for any element in any of its allotropic elemental forms.
What is true of the oxidation number?
It is an integer.

Why the oxidation number of Cr2O72- is 6?
It is true for chromium. But O shows 2asthe oxidation number.
What is the oxidation number of carbon in strontium carbonate?
In the carbonate CO32- the sum of the oxidation numbers is the ionic charge (true for all poyatomic ions) O is assigned -2 so C has +4. (maths 4 +(-6) = -2)

What is the oxidation state of h in H 2 g?
The oxidation state (or number) is zero. This is true for any element in any of its allotropic elemental forms.
How do you calculate protons and in ions?
The protons are always the same as their matching atomic number. This is also true of ions. Protons never change.
What is the oxidation number of Sn in element form?
Zero. This is true for all elements inn their elemental form.
What is the oxidation number for S in S 2?
Pure element has zero oxidation number. When forming ions it is equal the charge of ion.Atomic sulfur has oxidation number of 0. Its simple ion, sulfide carries oxidation status -2. While forming numerous compounds, the oxidation number of sulfur can vary form -2 to +6.
