<span>Mass of the solution = 0.17m
Kb for C6H5NH2 = 3.8 x 10^-10
We know Ka for C6H5NH2 = 1.78x10^-11
We have Kw = Ka x Kb => Ka = Kw / Kb
=> (C2H5NH2)(H3O^+)/(C2H5NH3^+) => 1.78x10^-11 = K^2 / 0.17
K^2 = 3 x 10^-12 => K = 1.73 x 10^-6.
pH = -log(Kw(H3O^+)) = -log(1.73 x 10^-6) = 5.76</span>
The electrical conductivity of a solution is the measure of the solution's ability to allow current to pass through it. This property is attributed to the amount of ions that are present in the solution. So, the answer to this item is IONS which are the positively or negatively charged particles.
Answer: NH3
Explanation: N2 + H2 yields NH3.
Answer:
. A homogeneous mixture of a solid in a gas
Answer:
Number of protons and electrons stay constant
Number of neutrons Differs
Explanation:
Isotopes are the different kinds of same element. Now, as we know quite well that an element can only have one atomic number, this means that the proton number is irrespective of the type of atom
Of the element. The proton number is the identity of the element.
As we know that the atom is electrically neutral, it means the number of electrons will always stay the same too.
Since isotopes are not alike in every respect, the number of neutrons differ. This means they have same atomic numbers but different mass numbers.
