Answer:
Nuclear fission is almost 5 times times more efficient than traditional fossil fuels at producing energy. That's a lot of energy packed into a small space. Nuclear energy is more efficient, which means it uses less fuel to power the plant and produces less waste.
Explanation:
<u>Answer:</u> 1.461 g of NaCl is dissolved in the solution.
<u>Explanation:</u>
Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L.
The formula used to calculate molarity:
.....(1)
Given values:
Molarity of solution = 0.050 M
Molar mass of NaCl = 58.44 g/mol
Volume of solution = 500.0 mL
Putting values in equation 1, we get:
Hence, 1.461 g of NaCl is dissolved in the solution.

Answer:
2
Explanation:
In calcium oxide, the calcium is electropositive in nature and to fulfil its octet, the calcium atoms lose two electrons to form the calcium cations whose valency is 2, hence the corresponding anion, i.e. the oxide anion must also have valency 2 to balance the positive charge on the calcium cation.
