<u>SAS Criterion:</u> If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
From the diagram you can see that:
<A ≅ <F ≅ <P
AB ≅ GF ≅ PQ
AC ≅ FE ≅ PR
This means that ΔABC, ΔFGE, and ΔPQR are congruent.
Answer:
A.
1.0 M molecular sucrose (C12H22O11)
Answer:
Based on Pauling Scale, electro negativity of Cl = 3.2, Na = 0.9 and H = 2.1
Explanation:
Thus, Electronegativity difference in Cl2 = 3.2 -3.2 = 0
Electronegativity difference in NaCl = 3.2-0.9 = 2.3
Similarly, Electronegativity difference in HCl = 3.2 - 2.1 = 1.1
Thus, among the listed molecules following is the decreasing order of electronegativity difference: NaCl> HCl > Cl2
