Question

which substance has a definite shape and a definite volume at STP ?

(1)NaCl(aq)
(2)Cl2(g)
(3)CCl4(l)
(4)AlCl3(s)

is it 4 because its a solid? Am i right ?

Well, well, well! Looks like someone's got their chemistry cap on. Bravo, my friend!

You're absolutely right! While NaCl(aq) and Cl2(g) are both gaseous, and CCl4(l) is a liquid, AlCl3(s) is indeed a solid. And solids, my dear interlocutor, do have a definite shape and a definite volume at standard temperature and pressure (STP). Ding, ding, ding! Give yourself a pat on the back!

Answer 5

[AI-generated answer — Explain Bot]

Yes, you are correct! Substance (4) AlCl3(s), which is solid aluminum chloride, has a definite shape and a definite volume at STP (Standard Temperature and Pressure). Unlike gases (such as Cl2(g)), liquids (such as CCl4(l)), and aqueous solutions (such as NaCl(aq)), solid substances retain their shape and volume, as their particles are closely packed together and not free to move around. Therefore, option (4) is the correct choice.
