Ferrous sulfate (FeSO4) is obtained by the reaction of aqueous ferric sulfate with gaseous sulfur dioxide and water according to the equation below:
Aqueous ferric sulfate = 
Gaseous sulfur dioxide = 
Water = 
Aqueous sulfuric acid = 
Aqueous ferrous sulfate = 
Thus, the balance equation becomes:
+
+

We know that there is 1 mole of Mn for every 1 mole of
KMnO4, therefore the molarity of Mn is similar with KMnO4:
Mn = 0.00300 M
Molar mass of Mn is 54.94 g / mol. Molarity (M) is moles /
L, therefore:
Mn = (0.00300 moles / L) * (54.94 g / mol) * (1000 mg / g)
<span>Mn = 164.82 mg / L = 164.82 ppm</span>
One of the most powerful laws in physics is the law of momentum conservation. ... For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
Answer:
pH = -1
Explanation:
A solution of 10 mol·L⁻¹ HCl is very acidic.
HCl is a strong acid, so it dissociates completely in water and
To get the pH, you take the negative logarithm of the hydronium ion concentration.
So, a pH = -1 represents a very acidic solution.
