Answer:

Warm air rises, resulting in a decrease air pressure.

Explanation:

Tornado is the rapid and violent rotation of column of air which move from the thunderstorm to the ground.

It is formed when there is collision between warm and cold air. The cold air which is more sense than the warm air is pushed over the warm air which result in thunderstorms. The warm air then rises which result in decrease air pressure causing an updraft. The updraft then begin to rotate as there are variations in wind speeds and directions.

A sample of pure alumina hydrate was obtained. A 5.000 g sample of the material was heated carefully in a vacuum oven until no m
lapo4ka [179]

Answer: The formula of the hydrated alumina is  Al_2O_3.5H_2O

Explanation:

Decomposition of hydrated alumina is given by:

Al_2O_3.xH_2O\rightarrow Al_2O_3+xH_2O


Molar mass of Al_2O_3 = 101.96 g/mol

According to stoichiometry:

(101.96+18x) g of  Al_2O_3.xH_2O decomposes to give 101.96 g of

Al_2O_3

Thus 5.000 g of   Al_2O_3.xH_2O decomposes to give=\frac {101.96}{(101.96+18x)}\times 5.000 of H_2O

But it is given 5.000 g of a sample of hydrated salt Al_2O_3.xH_2O was found to contain 2.6763 g of unhydrated salt

Thus we can equate the two equations:

\frac{101.96}{(101.96+18x)}\times 5.000=2.6763

x=5

Thus the formula of the hydrated alumina is  Al_2O_3.5H_2O
