Answer:

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus, and has other membrane-bound organelles that allow for compartmentalization of functions.The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.

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&#10;

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
