Answer:
Explanation:
The algebraic sum of all the oxidation numbers of all atoms in a neutral compound is zero.
In order to know the formula of the negative Sulfur ion in pyrite, we must determine its oxidation state.
Let us make the make the oxidation number of sulfur = x
Therefore, FeS₂:
+2 +2x = 0
+2 = -2x
x = -1
The formula of the negative ion is S⁻
A molocule i think sorry if im wrong
Answer: Thr reactions are balanced because both have the same products so they are balanced. This represents a balanced graph

Question:
Ammonium perchlorate NH₄ClO₄ is a powerful solid rocket fuel, used in the Space Shuttle boosters. It decomposes into nitrogen N₂ gas, chlorine Cl₂ gas, oxygen O₂ gas and water vapor, releasing a great deal of energy. Calculate the moles of water produced by the reaction of 2.5 mol of ammonium perchlorate. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.
Answer:
The number of moles of water produced by the reaction of 2.5 mol of ammonium perchlorate is 5 moles (of H₂O).
Explanation:
To solve the question, we are required to know the amount of each reagent and products there are in the balanced chemical reaction as follows
2 NH₄ClO₄ → N₂ + Cl₂ + 2O₂ + 4H₂O
From the chemical reaction stoichiometry, it shows that 2 moles of ammonium perchlorate, NH₄ClO₄ produces 4 moles of H₂O
Therefore 2.5 moles of ammonium perchlorate will produce moles of H₂O or 5 moles of H₂O.
