metal reacts with oxygen and they are forms the
corresponding oxides as shown below
Pl2O3 => having the Pl is showing the oxidation state +3 and oxygen shows the -2 oxidation state
this is an oxide and it is named as => paulium (III) oxide where (III) represents the the oxidation states of Paulium and oxide represents the presence of oxygen
answer => paulium oxide or paulium (III) oxide

POGIL-Stoichiometry How do chemists use balanced chemical equations? got bit D 23 mosquitoes? 10 He got Mol-aria Why? Chemists use balanced chemical equations as a basis to calculate how much reactant is needed or product is formed in a reaction. This is called Stoichiometry- (stoi-key-ah-meh-tree) Another way of looking at it is using the mole ratio from the balanced equation and information about one compound in the reaction to determine information about another compound in the equation. A mole ratio...
