Answer:VO(ClO4)3 i'm sure this is it
Explanation:
Volume of a sphere = 4/3 x pi x r^3
When put a fraction of volume constant 4/3 x pi cancels out.
So only cube of radii remains.
Radius of proton = 10^-15 m (Fact; remember it)
Radius of total Hydrogen atom = 0.529 × 10^−10 m
Fraction of Volumes : R'^3/R^3 = (R/R)^3
Fraction = ((10^-15)/(0.529 × 10^−10m.))^3= (1/52900)^3 =
6.755 x 10^-15
Answer:
pH = 2.03
Explanation:
The pH can be calculated using the following equation:
(1)
The concentration of H₃O⁺ is calculated using the dissociation constant of the next reaction:
CH₃COOH + H₂O ⇄ CH₃COO⁻ + H₃O⁺
1.00 M
Solving the above equation for H₃O⁺, we have:
(2)
The dissociation constant is equal to:
Now, by solving the equation of the solubility product for Herbigon, we can find [CH₃COO⁻]:
CH₃COOX ⇄ CH₃COO⁻ + X⁺
5.00x10⁻³ M
By entering the values of [CH₃COO⁻] and Ka, into equation (2) we can calculate [H₃O⁺]:
Hence, the pH is:
Therefore, the pH must be 2.03 to yield a solution in which the concentration of X⁺ is 5.00x10⁻³M.
I hope it helps you!
Answer:
Iron, as well as iron alloys, rusts because of a chemical reaction known as oxidation. When iron is exposed to moisture or oxygen, oxidation occurs. During this chemical reaction, iron is converted into iron oxide
Answer:
Group B is the control group
Explanation:
In an experiment, a control group is the standard to which comparisons are made in an experiment.
