Answer:
The correct formula is the first one.
Explanation:
Copper has two valences I and II, in this example, it's mentioned that copper's valence is I.
Then we have to look in all the formulas for one formula where copper has that valence, and that valence is in formula 1 and 3. Number 4 is discarted that formula is incorrect, that formula doesn't exist.
Number 2 is also discarted because in this formula Cu has a valence of 2.
Number three is discarted because here Bromide has a valence of 2 and that is incorrect, Bromide's valence is 1.

Answer:
The system prevents a consumer from accruing debt via electricity use, as it only allows the customer to use electricity which has been paid for upfront.
this gives the advantage of not allowing the consumer to rack up debt
the disadvantage for the consumer comes when they cannot afford to prepay in a time of financial difficulty - as the system now renders them as having no electricity as well as no money
Answer:
The voltage operating is the 85,20563362
Explanation:
Power is the relation between Voltage and Current so knowing the resistance is going to be constant the equation of power can be just replacing in voltage terms:
1. 
using also Law OHM
2. 
Replacing 2 in the equation 1 so all the data are going to be in Voltage terms:
1. 
⇒ 
Ω
So the resistance is constant so the current is going to be the same at the other Power 36 W:
⇒
