a) NH₃ molecules have stronger intermolecular attractions than CH₄ molecules.
Explanation:
Ammonia molecules have stronger intermolecular attractions compared to methane.
Ammonia molecules have london dispersion forces and hydrogen bonds between their molecules.
Methane molecules have only london dispersion forces in their structure.
- hydrogen bonds are very strong attractive forces between molecules in which the hydrogen of a molecule is attracted by a more electronegative atom of another usually oxygen, nitrogen and fluorine.
- London dispersion forces are weak forces of attraction between heteronuclear atoms.

I believe you just look at your periodic table for this value. I don't think there is any math involved.
Therefore one mole of Mg = 24.305g.
by putting to much current through it ?
For Less number of oxygen atoms will be less acidic. Therefore, the rank will be.... So there is 1 oxygen atom bonded to each of the 2 nitrogen atoms.
For HNO3 or {HONO}2. So there are 3 oxygen atoms bonded to the nitrogen.
For HNO2 or HONO. So there are 2 oxygen atoms bonded to the nitrogen.
Less number of oxygen atoms will be less acidic. Therefore, the rank will be...
HNO3>HNO2>H2N2O2
Acid strength is the tendency of an acid, symbolized by the chemical formula, to dissociate into a proton, and an anion, The dissociation of a strong acid in solution is effectively complete, except in its most concentrated solutions.
The strength of a weak organic acid may depend on substituent effects. The strength of an inorganic acid depends on the atom’s oxidation state to which the proton may be attached. Acid strength is solvent-dependent. For example, hydrogen chloride is a strong acid in an aqueous solution but is a weak acid when dissolved in glacial acetic acid.
