Answer:
a) 
b) 
c) 
Explanation:
Hello,
In this case, in each reaction we must subtract the Gibbs free energy of formation the reactants to the Gibbs free energy of formation of the products considering each species stoichiometric coefficients. In such a way, the Gibbs free energy of formations are:
So we proceed as follows:
a)
b)
c)
Regards.
Eight, since it has eight valence electrons.
Answer:
3 chlorine atoms are needed because each chlorine atom accepts one of Aluminum three valence electrons to obtain a full octet and makes chlorine a negatively charged anion
Explanation:
How many chlorine atoms are needed when making Aluminium Chloride?
The formular for aluminium chloride is given as; AlCl3
In the compound, Aluminium has a valency of +3 and the three chlorine atoms each have a valency of +1 to make the compound a neutral compound.
That meas we can represent AlCl3 as Al³⁺ and 3Cl⁻
The correct statement is;
3 chlorine atoms are needed because each chlorine atom accepts one of Aluminum three valence electrons to obtain a full octet and makes chlorine a negatively charged anion
