Answer:
The value of dissociation constant of the monoprotic acid is .
Explanation:
The pH of the solution = 2.46
Initially
0.0144 0 0
At equilibrium
(0.0144-x) x x
The expression if an dissociation constant is given by :
The value of dissociation constant of the monoprotic acid is .
Absolutely nothing a neutron has a neutral charge
Answer: 28.40
Explanation:
For A(27.977 u)
Mass number = 27.977
Abundance = 78.21%
For B (28.976 u)
Mass number = 28.976
Abundance = 1.346%
For C(29.974 u)
Mass number = 29.974
Abundance = 20.444%
Averages atomic mass
= (Mass of A x abundance of A)/100 + (Mass of B x abundance of B)/100 + (Mass of C x abundance of C)/100
= (27.977x78.21)/100 + (28.976x1.346)/100 + (29.974x20.444)/100
= 21.8808117 + 0.39001696 + 6.12788456
= 28.40
If poison expires it becomes less poisonous and soon it won't be poisonous. Depends on what kind of poison as well
Answer:
There are 6.024 grams of sodium hydroxide in the solution.
Explanation:
Moles of sodium hydroxide = n
Volume of sodium hydroxide solution = 251.0 mL = 0.251 L
Molarity of the sodium hydroxide = 0.600 M
Mass of 0.1506 moles of NaOH :
There are 6.024 grams of sodium hydroxide in the solution.
