When the barometer rises it means air pressure goes up. When that happens there is clear skies and little clouds. So you would be expecting hotter weather.
Answer:
B has water as solvent
Explanation:
An aqueous solution is a solution in which the solvent is water.
En Quimica, una reaccion de deshidratacion es una conversion que implica la perdida de agua de la molecula o ion que reacciona.Las reacciones de deshidratacion son procesos comunes, lo contrario de una reaccion de hidratacion.Los agentes deshidratantes comunes ultilizados en la sintesis organica incluyen acido sulfurico y alumina.
Answer:
cm^3 —> dm^3
divide by 1000
159.5 — Mr of CuSO4
n (moles in mol) = c (concentration in mol/dm^3) * v (volume in dm^3)
0.100 mol of CuSO4 dissolved in 0.5dm^3 of water
calculate for mass of CuSO4 dissolved in 0.03dm^3 (30cm^3) of the solution
n = m/Mr
m = n*Mr
if 0.1 mol is dissolved in 0.5 dm^3 of water
0.5/0.03 ≈ 16.66666667
0.1 = 0.05
0.1 / 16.66666667 = 0.006
0.5 / 16.66666667 = 0.03
0.006 (mol of CuSO4) = 0.03 (dm^3 solution)
0.006 * 159.5 = 0.957 g
I think this is the answer
Answer: Icebergs are produced when large pieces of ice break off from the front of a glacier during a process called calving.
Explanation:
A glacier breaks into pieces and forms icebergs.
The process of breaking of a glacier into icebergs when large pieces of ice breaks is known as calving.
Or we can also say that icebergs are produced when large pieces of ice break off from the front of a glacier during a process called calving.
