<h3>Answer:</h3>
1.5 × 10⁸ Kg of CO₂ / Year
<h3>Solution:</h3>
According to statement,
1 kwh generation produces = 0.73 Kg of CO₂
So,
700 kwh generation will produce = X Kg of CO₂
Solving for X,
X = (700 kwh × 0.73 Kg) ÷ 1 kwh
X = 511 Kg of CO₂ / Year
Also, as calculated,
1 household produces = 511 Kg of CO₂ / Year
Then,
300,000 households will produce = X Kg of CO₂ per Year
Solving for X,
X = (300000 households × 511 Kg) ÷ 1 household
X = 153300000 Kg of CO₂ / Year
Or,
X = 1.5 × 10⁸ Kg of CO₂ / Year
Answer:
c.- How much of the reactants are needed and how much product will made.
Explanation:
The moles is the matter unit used in chemistry to simplify some calculations, instead of using grams. Also the moles are very useful because the chemical reaction can be balanced.
When a Chemical reaction is balanced, then it can be easily to calculate how many moles are necessary to add in a process to obtain a quantity of grams of a product.
Oxidation is a process in which electrons are lost from the substance. Since electrons are lost, oxidation state increases.
In the above reaction, we can see that oxidation state increases for Mn from 0 to +2. That mean Mn is undergoing oxidation.
We have
The oxidation state decreases for Cu, that means Cu undergoes reduction.
The formula to calculate cell potential is
Let us plug in the given Eox and Ered values.
The overall cell potential is +1.52V
