Answer 2

HELP!!!!

Answer 3

You can guess what the answer is even without knowing anything about chemistry. C2H6, H2O, and Cl2 is all liquid/gas under room temperature, and the only one that's solid is strontium chloride (SrCl2), so that's your answer.

Answer 4

as for the reason why this is the case, look at inter-molecular forces (aka IMF). C2H6 and Cl2 only have london dispersion, so it's the weakest out of the four answers so that can't be it. H2O, even if it has two intermolecular hydrogen bonds, is still weaker than the electrostatic force of attraction between the Sr and the Cl2 ions. So that's why :)

Answer 5

Ask me if you still have questions :)
