Answer:
4.3043x10^24
Explanation:
Atoms(H) = (3.575 mol H2S/1)(2 mol H/1mol H2S)(6.02x10^23/1molH)
Simple stoicheometry problem. Sorry for taking so long, took Chem sophomore year, its been a while
Answer:
Freezing
Melting
Condensation
Evaporation
Sublimation
Deposition
Explanation:
From the diagram,
(1) Liquid⇒Solid (Freezing)
Freezing: This is the process by through which a substance change from liquid to solid.
(2) Solid⇒Liquid (Melting)
Melting: This is a process through which a substance change from solid to liquid
(3) Liquid⇒gas (Evaporation)
Evaporation: This is a process through which a substance change from liquid to gas.
(4) gas⇒Liquid (Condensation)
Condensation: This is a process through which a substance change from gas to liquid
(5) Solid⇒gas (Sublimation)
Sublimation: this is a process through which a subtance change from solid to gas
(6) gas⇒solid (Deposition)
Deposition: This is a process through which gas transform into solid.

Answer:
(a) m = 0.327 m.
(b) m = 4.57 m.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to solve this problem by firstly considering the fact that the molality is computed by dividing the moles of solute by the kilograms of solvent, in this case water; in such a way, we proceed as follows:
(a) We firstly calculate the moles of 36.2 grams of sucrose as its molar mass is 342.3 g/mol:
Next, the kilograms of water in this case are 0.323 kg so that the molality will be:
(b) In this case, we directly realize that the kilograms of water are now 1.889 kg so that the molality will be:
Clearly, the both of them in molal, m, units.
Regards!
Sometimes it can be true, but if you think of it another way: the warmer the water is, the quicker the substance dissolves in that...
Meaning you have to give heat to the system (ex. tea) in order to get e.g. the sugar dissolved :) However, in extreme cases heat can also be released!
