Answer:
In fact this should be considered more of a continuum. For example salt dissolving in water is usually considered to be a physical change, however the chemical species in salt solution (hydrated sodium and chlorine ions) are different from the species in solid salt.

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
Answer:
It is the main factor affecting the planet's average temperature, but it is not the only one. The temperature of the Earth is also influenced by the composition of the atmosphere, which contains heat-trapping greenhouse gases and other chemicals injected by volcanic eruptions and human activities.
Hope this helps °ω°
