Answer:
Dot structures make it easy to count electrons and they show the number of electrons in each electron shell.
Arrow and line diagrams show the spin of electrons and show every orbital.
Written configurations require minimal space and show the distribution of electrons between subshells.

Answer:
D. 2.0 M CuCl2
Explanation:
The ionic strength of a solution shows the concentration of its ions in that given solution of the compound. Dissolved ionic compounds always dissociate into ions. The total amount of ions in solution will definitely affect the properties of the solution. The concept of ionic strength was first introduced by Lewis and Randall in 1921 while describing the activity coefficients of strong electrolytes.
The ionic strength of CuCl2 is 6M as shown:
ionic strength = 0.5*[(+2)^2*2M + (1-)^2*4M] = 6 M
The higher the ionic strength of a solution, the greater its non ideal behavior.
CuCl2 shows the greatest ionic strength hence the greatest non ideal behavior.

Answer;
FeSO4 (aq) + H2 (g)
Explanation;
The reaction between iron and dilute sulfuric acid gives a salt and hydrogen gas. (iron (ii) sulfate and hydrogen gas).
The equation for the reaction is;
Fe(s) + H2SO4 (aq) = FeSO4(aq) +H2(g)
