A neutral isotope has 49 neutrons and 36 electrons. Identify the element symbol of this isotope and determine the mass number an
Marta_Voda [28]

Explanation:

In an atom , the relation between the subatomic particles of the atom are given as follows -

For a neutral atom ,  

Atomic number = number of protons = number of electrons ,

Mass number = number of protons + number of neutrons,  

Hence , from the given information of the question,  

number of neutrons = 49 ,

number of electrons = 36 ,

Hence , by using the above relation,

Atomic number = 36

number of protons = 36

Since ,

Mass number = number of protons + number of neutrons

Mass number = 36 + 49 = 85 .

By taking the help of periodic table , as atomic number = 36 ,

The elements is Krypton ( Kr )

Kr ⁸⁵₃₆

A solution of HCOOH has 0.16M HCOOH at equilibrium. The Ka for HCOOH is 1.8×10−4. What is the pH of this solution at equilibrium
kotykmax [81]

Answer:

pH=2.28

Explanation:

Hello,

In this case, for the acid dissociation of formic acid (HCOOH) we have:

HCOOH(aq)\rightarrow H^+(aq)+HCOO^-(aq)

Whose equilibrium expression is:

Ka=\frac{[H^+][HCOO^-]}{[HCOOH]}

That in terms of the reaction extent is:

1.8x10^{-4}=\frac{x*x}{0.16-x}

Thus, solving for x which is also equal to the concentration of hydrogen ions we obtain:

x=0.00528M

[H^+]=0.00528M

Then, as the pH is computed as:

pH=-log([H^+])

The pH turns out:

pH=-log(0.00528M)\\\\pH=2.28

Regards.
