Which of the following is a characteristic of nonmetals?

nonmetals do not conduct electricity.

nonmetals are often malleable.

nonmetals are often shiny and hard.

nonmetals are often ductile. which of the following is a characteristic of nonmetals?

nonmetals do not conduct electricity.

nonmetals are often malleable.

nonmetals are often shiny and hard.

nonmetals are often ductile.

For the question, the correct answer is "Nonmetals do not conduct electricity." This is a characteristic of nonmetals. Non-metals do not reflect light. Therefore, they are poor conductors of heat and electricity. Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help. 

2poclâ‚(g) ⇜ 2 pclâ‚(g) + oâ‚‚(g) â†gâ° = (2 mol)î”gfâ°(pclâ‚) – (2 mol)î”gfâ°(poclâ‚) = (2 mol)(–270 –(–502) kj/mol) â†gâ° = + 464 kj = â†hⰠ– tî”sâ° î”sâ° = 179 j/k ⇒ â†hâ° = â†gâ° + (298 k)(179 j/k) = –411 kj assuming that î”hâ° and î”sâ° do not depend on temperature, the temperature at which â†gâ° = 0 is where t = â†hâ°/î”sâ° = (–411 kj)/(0.179 j/k) = 2294 k. at that temp. keq = 1 for the reaction.
