Answer:
You need a mixture of positive and negative ions
Explanation:
From Faraday's 1st law of electrolysis,
Total electricity passed into system = Q = IT = 250 X 24 X 60 X 60
= 2.16 X 10^7 C
We know that, 96500 C = 1 F
∴ 2.16 X 10^7 C = <span>223.8 F
</span>
Now, number of moles of<span> MnO2 deposited = 223.8/2=111.9
</span>
Finally, 1 mole of MnO2 ≡ 86.94 g
∴ 111.9 mole of MnO2 ≡ 111.9 X 86.94 = 9728 g
Thus, <span>mass of MnO2 that will be deposited at anode = 9728 g</span>
Answer:
true is the correct ans of this question
Answer:
The correct answer is: <em>There must be potential energy in the bonds due to its particles position.</em>
Explanation:
Potential energy is a kind of energy which is stored in an object due to its position or configuration. For example, if there is a ball in the fifth floor of a building, it has a determined potential energy which is converted to kinetic energy when the ball fall down. The same is in the case of the chemical bonds: the particles or atoms have potential energy related to their relative positions in the system. In fact, chemical energy is considered a form of potential energy (stored in chemical bonds).
A scientist that studies the weather is called a meteorologist.
