4HCl + MnO₂ → MnCl₂ + 2H₂O + Cl₂
2Cl⁻ → Cl₂ + 2e⁻
MnO₂ + 4H⁺ + 2e⁻ → Mn²⁺ + 2H₂O
2Cl⁻ + MnO₂ + 4H⁺ → Cl₂ + Mn²⁺ + 2H₂O
Answer:
This is true because oxygen belongs to the non-metal part of the periodic table.
<span>1: Calculate the Formal Charge of C. Carbon (C) is in group 14, so that means it has 4 valence electrons. . 2: Calculate the Formal Charge of Oxygen on the Left. . 3: Calculate the Formal Charge of Oxygen on the Right. .<span>4: Check the Overall Charge.
I hope this helps:)

Answer: Option (A) is the correct answer.
Explanation:
Force acting on a dam is as follows.
F =
.......... (1)
Now, when we double the depth then it means H is increasing 2 times and then the above relation will be as follows.
F' = ![\frac{1}{2}\rho g\omega (2)^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Crho%20g%5Comega%20%282%29%5E%7B2%7D)
F' =
........... (2)
Now, dividing equation (1) by equation (2) as follows.
=
Cancelling the common terms we get the following.
=
4F = F'
Thus, we can conclude that if doubled the depth of the dam the hydrostatic force will be 4F.
