Answer:
The concentration of the chloride ion is 1.8 mM
Explanation:
Step 1: Data given
An aqueous solution contains 3.6 mM of total ions.
Step 2: The equation
NaCl(aq) → Na+(aq) + Cl-(aq) : two ions
Step 3: Calculate the concentration of the chloride ion
Two ions = 3.6 mM
Chloride ion = 3.6/2 mM= 1.8 mM
Sodium ion = 3.6/2 mM = 1.8 mM
The concentration of the sodium ions is 1.8 mM
The concentration of the chloride ion is 1.8 mM
The total concentration = 3.6 mM

Lamarck was the first person to propose a fully formed theory of evolution.
Answer:
The Earth's atmosphere is 78% nitrogen gas or N2. Even though there is so much nitrogen in the air, there is very little in the Earth's crust. It can be found in some fairly rare minerals such as saltpeter. Nitrogen can also be found in all living organisms on Earth including plants and animals.
