From the problem description you've given, I can't give an exact answer without a context. However, I found a similar problem with an illustration. Supposing this is the problem, we can set a mole balance:
n₁ = n₂ + n₃
Since n₃ is just part of n₁, it will always be less than n₁ because n₁ constitutes 100% mol A. Thus, the answer is letter C.
Types of Bonds can be predicted by calculating the
difference in electronegativity.
If, Electronegativity difference is,
Less
than 0.4 then it is Non Polar Covalent
Between 0.4 and 1.7 then it is Polar Covalent
Greater than 1.7 then it is Ionic
For Ca and K,
E.N of Calcium = 1.00
E.N of Potassium = 0.82
________
E.N Difference 0.18 (Non Polar Covalent)
For Ca and Mg,
E.N of Magnesium = 1.31
E.N of Calcium = 1.00
________
E.N Difference 0.31 (Non Polar Covalent)
For Ca and Br,
E.N of Bromine = 2.96
E.N of Calcium = 1.00
________
E.N Difference 1.96 (Ionic)
For Ca and S,
E.N of Sulfur = 2.58
E.N of Calcium = 1.00
________
E.N Difference 1.58 (Polar Covalent)
Result:
The bond between Calcium and Bromine is Ionic in Nature.
Answer: Protons have a positive charge. Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite. Neutrons have no charge.
