I know for a fact the correct answer is B
Answer:
The answer to your question is below
Explanation:
ionic compounds covalent compounds
1.- Mass it does not depend on the type of compound
2.- Conductivity -conduct electricity - do not conduct electricity
in solution.
3.- Color - Shiny - opaque
4.- Melting point - high - lower than ionic compounds
5.- Boiling point - high - lower than ionic compounds
6.- flammability - not flammable - flammable
The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
First, we have to know that we can put [H+] instead of [H3O+]
so, according to the reaction equation:
by using ICE table:
H2O ↔ H+ + OH-
initial 0 0
change +X +X
Equ X X
when Kw = [H+] [OH-]
and when we have Kw = 2.4 x 10^-14
and when [H+] = [OH-] = X
∴ 2.4 x 10^-14 = X^2
∴ X = √(2.4 x 10^-14)
= 1.55 x 10^-7
∴[H+] = 1.55 x 10^-7
