Answer:
Fe^2+(aq) + S^2-(aq) --------> FeS(s)
Explanation:
First let us look at the molecular equation;
Na2S(aq) + Fe(NO3)2(aq) --------> FeS (s) + 2NaNO3(aq)
Now, the net ionic equation usually shows the most important reaction that took place, in this case, the formation of the FeS precipitate.
Hence, ionically;
Fe^2+(aq) + S^2-(aq) --------> FeS(s)

Thermal energy isconverted to gas energy
Answer:
P₂= 116.7 atm
Explanation:
Here apply the Boyle's law equations that states :at constant temperature the volume of a dry mass of a gas is inversely proportional to its pressure.
This is simplified as;
P₁V₁=P₂V₂ where P is pressure and V is volume
Given that;
P₁=1
V₁=1.81 m³
P₂=?
V₂=1.55*10^-2 m³
Apply the formula
1*1.81 =P₂*1.55*10^-2 m³
1.81/1.55*10^-2 =P₂
P₂= 116.7 atm
