Melting points and boiling points of molecular compound are usually lower than ionic compounds. This is so as only a small amount of energy is required to overcome the weak intermolecular forces of attraction (Van de Waals forces) thus having lower m.p. and b.p.
Ionic compounds require a large amount of energy to overcome the strong electrostatic forces of attraction between the ions, hence having higher mp and bp
Answer:
c. 3.00 M HCl
Explanation:
From dilution formula
C1V1 = C2V2
C1=?, V1= 10.0ml, C= 1.5, V2= 20.0ml
Substitute and Simplify
C1×10= 1.5×20
C1= 3.00M
Answer:
Carbon comes from the air and soil, hydrogen comes from absorbing water, H20, and breaking it down into Hydrogen and oxygen :) (also where oxygen comes from)
Explanation:
A substance that undergoes change during a reaction, usually from coming in contact with another substance
in the periodic table, a set of properties repeats from row to row
