Answer:
Arsenic, As, has atomic number 33, which is the number of protons in the nuclei of its atoms. A neutral As atom would also have 33 electrons. The electron configuration of a neutral arsenic atom is [Ar]3d104s24p3
Explanation:
The correct answer is option A.
All the particles carry the same charge, which could be either positive or negative.
All the particles of substance X will have same charge on its surface, which is balanced by the oppositely charged ions in the water.
For example, soap solution (sodium palmitate) dissociates into ions:
C₁₅H₁₁COONa --> C₁₅H₁₁COO⁻ + Na⁺
The cations (Na⁺) passes into the water while the anions (C₁₅H₁₁COO⁻) form aggregates or colloids.
Answer:- 14.9 M
Solution:- Given commercial sample of ammonia is 28% by mass. Let's say we have 100 grams of the sample. Then mass of ammonia would be 28 grams.
Density of the solution is given as 0.90 grams per mL.
From the mass and density we could calculate the volume of the solution as:

= 111 mL
Let's convert the volume from mL to L as molarity is moles of solute per liter of solution.
= 0.111 L
Now, we convert grams of ammonia to moles on dividing the grams by molar mass. Molar mass of ammonia is 17 gram per mole.

= 1.65 mole
To calculate the molarity we divide the moles of ammonia by the liters of solution:

= 14.9 M
So, the molarity of the given commercial sample of ammonia is 14.9 M.
