Can someone help because I need the same answer.
A homogeneous mixture<span> is a </span>type of mixture<span> in which the composition is uniform and every part of the solution has the same properties. A heterogeneous </span>mixture<span> is a </span>type of mixture<span> in which the components can be seen, as there are two or more phases present.</span>
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:
Moist and warm temperatures
Explanation:
The observation that most likely indicates that only a chemical change has taken place is that the change cannot be reversed.
There are two types of change which matter undergoes;
- Physical change
- Chemical change
A chemical change leads to the formation of a new substance so it is usually irreversible.
On the other hand, a physical change is easily reversible. It often involves a change in shape, form or appearance of matter.
If a change is cannot be reversed, it is most likely a chemical change.
