<span>∆T = i * Kf * m
Kf(cryoscopic constant of water) = -1.858°C·kg/mol
i = 1 (for glycerin)
m = molality of solute(glycerin) = nos of moles of glycerin / mass of solvent(water)[n/M]
n = 30.7g/92.09g = 0.33337moles
M is deduced from the density of water which is 1Kg/1000ml(1Kg/L)
M = 376ml * (1Kg/1000ml) = 0.376Kg
m is thus; 0.33337moles/0.376Kg = 0.8866mol/Kg
=> ∆T = 0.8866mol/Kg * 1 * -1.858°C·kg/mol
∆T = -1.647°C
~ -1.65°C.</span>
Answer:
climate
Explanation:
Agriculture refers to the cultivation and growing of crops and vegetables that includes rice, wheat, barley, maize, potato, tomatoes, onion, mustard and other vegetables and fruits that are consumed by the humans.
China, the largest having the largest population of the world is mostly involved in agriculture. China has a favorable climatic conditions and seasons for cultivation of a large variety of crops. China grows mainly crops in the northeast part of China than wet rice.
Both temperature condition and precipitation favors the cultivation of crops. The northeast China experiences a hot and dry summers but bitterly cold winters. These regions receives a continual rainfall. All this conditions favors the crops cultivation in this part region of China.
A sustainable development is development that meets the needs of the present, without compromising the ability of future generations to meet their own needs.
hope it helps you so much
Answer:
at 4 p.m Baghdad located at 45°E
at 8p.m Indonesia is located at x°
we have
common difference in time =8p.m-4p.m=4hours =4×60min
again
we have
4min=1°
4×60min=4×60/4=60°
since time is in p.m on both so they lie in same direction
Therefore, longitude of Indonesia=60°E.
hope this helps you. thanks
