Answer:
(a) MgCl2 consists of Mg2+ and Cl- ions held together by ionic bonding forces;; PCl3 consists of polar molecules, so intermolecular dipole- dipole forces are present..
Explanation:
Well.. Hope it helps you..
Y-your welcome in advance..

A gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces.
All you need to do is change 5% into a decimal which would be 5/100 = .05
then multiply the decimal by the total volume to get the amount of active ingredients in ml
.05 * 56ml = 2.8 ml of active ingredient.
Hope that helps!

That's easier for you to come over and watch the answer to the question
Answer:
The chemical change in matter is results in a change in its identity and properties.
Explanation:
There are toe type of changes physical change and chemical change.
The chemical change change in matter lead to lost its identity and properties.
Chemical change:
The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.
These changes are irreversible
These changes occur due to chemical reactions
These may not be observed with naked eye
Example:
Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood
Boiling of egg: that change the chemical composition of protein in the egg .
The reaction of Hydrogen and oxygen:
H 2 (g) + O 2 (g) -------------------------------------> 2H 2O (l)
