Explanation:
Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds
Assuming that the complete question is the following:
Calcium hydroxide reacts with Aluminum sulfate to form aluminum hydroxide and calcium sulfate. Write the balanced formula unit equation for the reaction.
Then the balanced formula unit equation would be:
3Ca(OH)₂ + Al₂(SO₄)₃ → 2Al(OH)₃ + 3CaSO₄
This is a double replacement reaction, where the cations and anions are interchanged.
Balancing this reaction is based on the Law of Conservation of Mass, which estates that matter is not created nor destroyed, meaning that the number of atoms at the right and the left of the chemical equation needs to be the same. We add coefficients in front of each species that intervenes in the reaction in order to achieve that equality.
Have a nice day!

Answer:
a.) 4.9kj/mol
b.) -Br group
Explanation:
first all of your question did not make mention of the groups in the table.
here it is:-
axial group ΔG°(kj/mol) group ΔG°kj/mol
CN -O.8 NH₂ -5.9
Br -2.4 CH₃ -7.3
OH -3.9 1,2-gauche 3.8
The 6 axial groups are bonded one on each carbon and also they are parallel and also alternate from up to bottom.
a.)
to get the absolute ΔG;
ΔG = -2.4-(-7.3)
= -2.4+7.3
= 4.9KJ/MOL
b.)
the axial group in this compound which is in the axial position in the energetically preferred chain conformation is the -Br group

Answer:
31.19
Explanation:
H= MC x Temperature change
100 = (20/1000) x 4200 x A
100= 84A
A= 1.19
A=X-30
1.19=X-30
X=30+1.19
X=31.19
