Explanation: -Nitrogen is the element that may form diatomic molecules held together by triple covalent bonds. -Nitrogen is an element that occurs as a diatomic molecule in its gaseous state. This element only exists in the diatomic form with triple bonds between the two atoms.
Answer:
Explanation:
A solubility curve is a graph of solubility, measured in g/100 g water, against temperature in °C. Solubility curves for more than one substance are often drawn on the same graph, allowing comparisons between substances
Here, as they both are physical things without any magnetic property & density difference, screening would be best.
In short, Your Answer would be Option C
Hope this helps!
Answer:A
Explanation:
The melting points of solids depend in the relative sizes of ions in the ionic lattice. The smaller the relative sizes of the ions, the higher the lattice energy and the stronger the lattice hence higher melting point. Comparing relative ionic sizes, fluoride ion is lesser in size than chloride ion hence NaF has a higher melting point than NaCl.
