Answer:
Intermolecular
Explanation:
Intermolecular forces are the forces operating between the two molecules. These forces are of short rang forces and also known as week intermolecular forces.
These forces only exist when molecules get close together by force of by cooling.
Example:
Hydrogen bond (intermolecular forces) exist in liquid water molecules but when we heat it the water molecule escape from surface by as hydrogen bond break by heating.
Compressed Natural Gas:
In this case the molecules of natural gas presses and the come closer so the distance between the molecules become less and force of attraction increase that attraction (intermolecular force ) is due to short distance.
Answer:
b. is always a weak electrolyte.
Explanation:
Such compounds of low solubility dissociates partly and hence cannot be strong electrolytes
Answer:
The difference between normal salt and acid salt is that acid salt is basically made up of strong acid and also including a weak base. However normal salt is practically made up of strong base or even a weak acid and also a weak base. Acid salt or in a more logical term known as acidic salt ionises into a type of form of H + ions which is more than OH- ions, which is in a water solution. But even than normal salt ionises into a form of eqaul number of H+ ions and OH- ions in this so called water solution.
Answer: a. 7.31 g
b. 20.4 %
Explanation:
To calculate the moles :
According to stoichiometry :
3 moles of require = 1 mole of
Thus 0.645 moles of will require= of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 3 moles of give = 2 moles of
Thus 0.645 moles of give = of
Mass of
Thus theoretical yield for this reaction under the given conditions is 7.31 g.
b)
The percent yield for this reaction under the given conditions is 20.4 %
