No compound is 100% ionic. If the bond involves the same atoms (a homonuclear bond, A-A) then the bond must be 100% covalent because neither atom has the ability to attract the electron pair more strongly than the other. ... The reason for this is that an electron is never completely transferred from one atom to another.
Answer:
2.61 L
Explanation:
p1v1 = p2v2
p1v1 / p2 = v2
98 * 2 / 75 = v2 = 2.61 L
Answer:
pH=4.05
Explanation:
C7H6O2 -> C7H6O- + H+
ka= [C7H6O-] [H+]/[C7H6O2]
During equilibrium
[C7H6O-]= [H+]= x^2
[C7H6O2]=0.12-x
Replace
ka= x^2/0.12-x
6.5 x10^-5= x^2/0.12-x
7.8x10^-6 - 6.5 x10^-5x=x^2
x^2+ 6.5 x10^-5x - 7.8x10^-6
Solution of quadratic equation
x=8.8 x10^-5
pH= -log [H+]= -log 8.8 x10^-5=4.05
Answer:
2334.1136 Joules
Explanation:
Q= 65.6 g (4.186)(8.5)
If it's suppose to be in kilograms, the answer will be 2.3341136 Joules.
