- P2H2 Oxidation State - Diphosphene
P2H2 has an oxidation number of +1. In P2H2, the oxidation
number of H is -1
- H2C2O4 Oxidation State - Oxalic Acid
C has an oxidation number of +3 in H2C2O4. O has an oxidation
number of -2 in H2C2O4. H2C2O4 has an oxidation number of +1.
- CrO2 Oxidation State - Chromium(IV) Oxide
CrO2 has an oxidation number of +4.
<h3>Explain oxidation?</h3>
The oxidation state, also known as the oxidation number, is an atom's hypothetical charge if all of its bonds to other atoms were fully ionic.
The sum of the oxidation states of all the atoms in an ion equals the ion's charge.
A substance's more electronegative element is given a negative oxidation state. The one that is less electronegative is given a positive oxidation state.

a. 30 moles of H₂O
b. 2.33 moles of N₂
<h3>Further explanation</h3>
Given
a. 20 moles of NH₃
b. 3.5 moles of O₂
Required
a. moles of H₂O
b. moles of N₂
Solution
Reaction
4NH₃+3O₂⇒2N₂+6H₂O
a. From the equation, mol ratio NH₃ : H₂O = 4 : 6, so mol H₂O :
=6/4 x mol NH₃
= 6/4 x 20 moles
= 30 moles
b. From the equation, mol ratio N₂ : O₂ = 2 : 3, so mol N₂ :
=2/3 x mol O₂
= 2/3 x 3.5 moles
= 2.33 moles
Answer:
Not really fun facts about hazardous waste
Explanation:
four characteristics of hazardous waste are: ignitability • corrosivity • reactivity • toxicity. These things should be thrown away a proper way to reduce pollution.
Answer:
Alkali metal hydroxides can be used to test the identity of metals in certain salts. The colour of the precipitate will help identify the metal : Calcium hydroxide is soluble; no precipitate is formed.
