Gr terlarut = 36 gr
<span>Mr terlarut = 180 </span>
<span>gr pelarut = 250 gr </span>
<span>Kb air = 0,52 °C kg/mol </span>
<span>Tb larutan = ........? </span>
<span>--------------------------------------... </span>
<span>ΔTb = Kb.m.i </span>
<span>ΔTb = Kb. (gr t / Mr t) . (1000/ gr p) .i </span>
<span>ΔTb = 0,52 x (36/180) x (1000/250) x 1 </span>
<span>ΔTb = 0,416 °C </span>
<span>Tb = 100 + ΔTb </span>
<span>Tb = 100 + 0,416 </span>
<span>Tb = 100,416 °C</span>
Cu(OH)2 is insoluble in water
Answer:
B. the products have a smaller number of available energy microstates than the reactants.
Answer:
The partial pressure of the 
in the final mixture is 200 kPa.
Explanation:
Pressure of nitrogen gas when the two tanks are disconnected = 500 kPa
Pressure of the carbon-dioxide gas when the two tanks are disconnected = 200 kPa
Moles of nitrogen gas =
Moles of carbon dioxide gas =
After connecting both the tanks:
The total pressure of the both gasses in the tank = p = 250 kPa
According to Dalton' law of partial pressure:
Total pressure is equal to sum of partial pressures of all the gases
Partial pressure of nitrogen =
Partial pressure of carbon dioxide=
The partial pressure of the in the final mixture is 200 kPa.
Answer:
Two types of substances will dissolve in water: ionic compounds, such as sodium chloride (NaCl, or table salt) and compounds composed of larger molecules that have a net charge due to the arrangement of their atoms. Ammonia (NH3) is an example of the second type.
Explanation:
