Only CH4 is covalently bonded. All other compounds are ionic compounds.
So A is the answer.

Answer:
For instance look at N (Nitrogen), you will see the atomic mass is 14.00674 grams. So that means if you had 1 mole of nitrogen atoms, it would weight, 14.00674 grams. Now we have to get what fraction of a mole you have. To start, you need know that all a mole means is you have 6.022 x 1023 atoms of that type.

Copper(I) sulfate, also known as cuprous sulfate and dicopper sulfate, is the chemical compound with the chemical formula Cu2SO4 and a molar mass of 223.15 So its "Cu2s"
Answer:
the molecular formula is C₁₄H₈O₂
Explanation:
Given that
The freezing point of camphor is lowered by 22.3°C
Amount of anthraquinone is 1.32g
depression constant is 40°C.kg.mol
Use the freezing-point depression equation
Molecular weight of solute, m =
m = 208g/mol
empirical formula of Anthraquinone is C7H4O
empirical formula weight = 104 g/mol
m = Molecular formula weight / empirical formula weight
m = 208 / 104
208.2 / 104.1 = 2
molecular formula = (C₇H₄O)₂
so, the molecular formula is C₁₄H₈O₂
