They are on the last level of the atoms
Answer:
First Method: Vacuum Distillation and Chromatographic separation of the remains that were precipitated out from the peel.
Second Method: Extraction of components from orange peels by help of precipitation procedures that are mostly done <em>In Situ. </em>Those components can be recovered using the saponification process. Then these are examined under UV light spectroscopy. Now, the existence and extent of carotenoids can be determined by checking the levels of anti-oxidants.
Solution:
Molality:-It is a measure of the concentration of a solute in a solution in terms of amount of substance in a specified amount of mass of the solvent
Therefore,
Molality = moles solute / kg solvent
Therefore kg solvent = moles solute / molality
moles solute = mass / molar mass
= 25.31 g / 101.1 g/mole
= 0.2503 mole
kg solvent = 0.2503 mole / 0.1982 m
= 1.263 kg
= 1263 g
This is the required answer.
When the positive ions and negative ions react, they become neutral
A chemical property of soda ash is that it is an alkaline compound , of pH 11.6 in aqueous solution. The chemical name of soda ash is sodium carbonate. It is a sodium salt of carbonic acid and occurs as a white crystalline compound. It has a cooling alkaline taste. It can be found in the ashes of many plants. It is produced in large quantities from sodium chloride (common salt). It can be found as a mineral in mineral deposits of natron usually in seasonal lakes when the lakes dry up.
