The compound with the highest standard free energy of formation is O3(g)
The conductance of the electric current through the electrolytic solution increases with increase in concentration.
<h3>What is electrolysis?</h3>
The term electrolysis has to do with a situation in which liquids conduct electricity by the movement of ions.
The conductivity of the solution depends on the ions present in the solution. Thus, the conductance of the electric current through the electrolytic solution increases with increase in concentration.

A formula unit of the nitrate salt of Q is Q(NO3)2.
<h3>What is IUPAC nomenclature?</h3>
The IUPAC nomenclature was put together by the international Union of Pure and applied chemistry in order to have a uniform way of naming compounds.
We shall now find the names of the compounds;
1) Na* and HPO4²- ; sodium hydrogen tetraoxophoshate V
2) Potassium cation and cyanide anion ; Potassium cyanide
3) Calcium cation and hypochlorite anion; Calcium oxochlorate I
Knowing that the valency of NO3^- is one and that the compound formed between Q and CO3²- has the formula QCO3 we can conclude that a formula unit of its nitrate salt is Q(NO3)2.

Answer:
Q = 25.6 j
Explanation:
Given data:
Energy needed= ?
Mass of lead = 10.0 g
Initial temperature = 30 °C
Final temperature = 50°C
Cp = 0.128 j/g.°C
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 50°C - 30°C
ΔT = 20°C
Now we will put the values in formula.
Q = 10 g × 0.128 j/g.°C × 20°C
Q = 25.6 j
