The strength of a covalent bond depends upon the size of the atoms and the bond order. In general short bonds are strong bonds.
1. For each pair of covalently bonded atoms, choose the one expected to have the higher bond energy.
(A) C≡C
(B) C=C (A, B)
(C) C=N
(D) C-N (C, D)
2. The strength of a covalent bond depends upon the size of the atoms and the bond order. In general short bonds are strong bonds.
For each pair of covalently bonded atoms, choose the one expected to have the higher bond energy.
(A) N-N
(B) N≡N (A, B)
(C) C≡O
(D) C=O (C, D)
3. The length of a covalent bond depends upon the size of the atoms and the bond order.
For each pair of covalently bonded atoms, choose the one expected to have the shortest bond length.
(A) C≡C
(B) C=C (A, B)
(C) C=N
(D) C-N (C, D)
4. The length of a covalent bond depends upon the size of the atoms and the bond order.
For each pair of covalently bonded atoms, choose the one expected to have the shortest bond length.
(A) H-I
(B) H-Cl (A, B)

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
