Explain preparation of alkanes C--C from industrial source for industrial preparation of alkane​
Dmitrij [34]
Alkanes can be prepared from carboxylic acid via the removal of carbon dioxide. This process is known as decarboxylation. It produces alkane with a carbon atom lesser than that present in the carboxylic acid.

How many grams of titanium could be obtained from a 27.00 mole sample of Ti6Al4V?
Yakvenalex [24]

#7754.9g#

If the sample was measured in grams, we would first need to convert it to moles and then determine the amount of titanium. Because we already have the sample in a molar quantity, the moles of titanium is simply the formula ratio – 6 moles of titanium per mole of compound.
So, we have #6 xx 27 = 162# moles of titanium. Converting this to mass from the gram molecular weight, we obtain is
#162 xx 47.87 = 7754.9g#

Which of these solutions has the highest freezing point?
ANEK [815]

Answer: 1.0 M molecular sucrose (C₁₂H₂₂O₁₁).


Explanation:


1) The depression of the freezing point of a solvent when you add a solute is a colligative property.


2) Colligative properties are those physical properties of solutions that depends on the number of solute particles dissolved into the solution.


3) The relation between the number of solute particles and the depresson of the freezing point is proportional: the greater the number of solute particles the greater the freezing point depression.


4) You need to find the solution with the highest freezing point, this is the solution in which the freezing point decreased the least.


5) Then, that is the solution with least number of solute particles.


6) Since all the given solutions have the same molarity (1.0 M), you only have to deal with the possible ionization of the different solutes.


7) NaCl, CaBr₂, AlBr₃, and KCl are ionic compounds, so each unit of them will ionize into two, three, four, and two ions, respectively, while sucrose, being a covalent compound does not dissociate.


Then, 1.0 M solution of sucrose will have less solute particles than the others, and will exhitibit the lowest freezing point depression, meaning that it will have the highest freezing point of the given solutions.
