H - Harmful to people and property
Y - You can't taste it
D - Disrupts cell membranes
R - Reactive Hydroxyl Radical
G - Gene and DNA mutations
E - Explosive compounds
N - Neurotransmitters can be critically altered
M - Most people don't know what it its
O - Only people who look into it will find out
N - Nothing can survive without it
O - Otherwise safe
X - X marks the spot, you can find it on many maps
I - Included in everything
D - Drinkable, it's safe
E - Especially because it's WATER, H2O
Answer:
11%
Explanation:
1) Calculate van 't Hoff factor:
Δt = i Kf m
0.31 = i (1.86) (0.15)
i = 1.111
2) Calculate value for [H+]:
CCl3COOH ⇌ H+ + CCl3COO¯
total concentration of all ions in solution equals:
(1.11) (0.15) = 0.1665 m
This is a molality, but we will act as if it a molarity since we will assume the density of the solution is 1.00 g/cm3, which makes the molarity equal to the molality.
0.1665 = (0.15 − x) + x + x
x = 0.0165 M
3) Calculate the percent dissociation:
0.0165/ 0.15 = 11 %
Answer:
a. n = 3
b. n = 4
Explanation:
n is just the number in front of the orbital, as n represents the energy level of the orbital.
