<u>Answer:</u> The symbol of the anion is
<u>Explanation:</u>
Atomic number is defined as the number of electrons or number of protons that are present in a neutral atom. It is represented as Z.
Z = Atomic number = Number of electrons = Number of protons
Mass number is defined as the sum of number of protons and number of neutrons present in an atom. It is represented as A.
A = Mass number = Number of protons + Number of neutrons
We are given:
Number of protons = 33
Number of neutrons = 41
Number of electrons = 36
As, the number of electrons are more than the number of protons. This means that this atom that is negatively charged species known as anion.
The element having atomic number as 33 is Arsenic.
The symbol of the anion is

Answer:
ΔG for the given system is 28.421 kJ. The system is non spontaneous.
Explanation:
ΔH = 147 kJ =147,000 J= Enthalpy of the system
ΔS = -67.0 J/K = Entropy change
T = 149 °C = 422.15 K = Temperature of the system
((T)°C=273.15 +T K)
ΔG = Gibbs free energy ?
The Gibbs free energy 's expression is given by:
ΔG = ΔH - T ΔS
- ΔG > 0 , non spontaneous
- ΔG < 0, spontaneous
ΔG = 28,421 J = 28.421 kJ
Since, value of Gibbs free energy is positive this means that reaction is non spontaneous.
