Answer: D or B but i think D because iron will react slower with tap water than Hydrochloric acid
Answer:
+6
Explanation:
We are given;
We are required to determine the oxidation number of S in the compound.
We need to know that;
- The total oxidation number of this compound is Zero
- Oxidation number of Ba metal is +2
- Oxidation number of Oxygen atom is -2
- There is 1 atom of Ba, 1 atom of S and 4 atoms of O in the compound.
Therefore; assuming oxidation number of S is x
Then, (1× 2) + (1 × x) + ( 4 ×(-2)) = 0
2 + x - 8 = 0
x = 6 or +6
Thus oxidation number of Sulfur in BaSO₄ is +6.
The answer to ur question would be 8.0x10^1
Potassium hypochlorite when dissolved in water would dissociate into ions namely the potassium ions and the hypochlorite ions. Furthermore, hypochlorite ions would interact with water molecules and would decompose further. The dissociation reactions are as follows:
KClO <=> K+ + ClO-
ClO- + H2O <=> HOCl + OH-
Adding the two reactions, would give
KClO + ClO- + H2O = K+ + HOCl + OH- + ClO-
The two ClO- ions in both sides would cancel giving us the net ionic equation:
KClO + H2O = K+ + HOCl + OH-
