1.78L x (3.00M/1L) = 5.34
6.32 KJ is how much heat is given off
Mass of solute = 25.8 g
mass solution = 212 g
% =( mass of solute / mass solution ) x 100
% = ( 25.8 / 212 ) x 100
% = 0.122 x 100
= 12.2 %

Answer:
A = B < D < C
C - S
Cl - Cl
F ← H
Si → O
Explanation:
The polarity of a bond increases with the increase in the difference in electronegativity. The dipole moment is represented with an arrow pointing the more electronegative atom.
A: carbon-sulfur
C - S
ΔEN = |EN(C) - EN(S)| = |2.5 - 2.5| = 0
B: chlorine - chlorine
Cl - Cl
ΔEN = |EN(Cl) - EN(Cl)| = |3.0 - 3.0| = 0
C: fluorine – hydrogen
F ← H
ΔEN = |EN(F) - EN(H)| = |4.0 - 2.1| = 1.9
D: silicon - oxygen
Si → O
ΔEN = |EN(Si) - EN(O)| = |1.8 - 3.5| = 1.7
The order of increasing polarity is A = B < D < C.
