<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
Hey there !
Molecular Weight: 262.86 g/mol
Volume in liters : 1,000 mL => 1,000 / 1000 => 1 L
Number of moles of solution :
number of moles = volume x molarity
number of moles = 1 x 0.3 => 0.3 moles
Therefore:
1 mole Mg₃(PO₄)₂ ------------------- 262.86 g
0.3 moles ----------------------------- mass of Mg₃(PO₄)₂ ??
mass of Mg₃(PO₄)₂ = 0.3 x 262.86 / 1
mass of Mg(PO₄)₂ => 78.858 g
Hope this helps!

Explanation:
it's 3 dollars per 12 eggs so 3/12
simplify 3/12 by dividing both numbers by 3 so you get 1/4
you should know what 1/4 of a dollar is
or think of it this way 12 eggs are 3 dollars so every 4 eggs is one dollar. divide 1 dollar by 4 eggs
The rules is that, the more reactive the substance, the harder it is to extract. The reason is mainly due to the fact that you have to find a specific solvent to react the substance only, not the others.Basing on the list of reactivity of metals as shown in the picture, Zn is more reactive than Ag. Then, that means that Ag is easier to recover.
