Question

Choose the orbital diagram that represent the ground state at the nitrogen atom. Given the two resonance structures below, determine the more stable Lewis structure. In the more stable Lewis structure al CH_3CNO, the formal charge on N is ______ and the formal charge on O is _______. a. 0, 0 b. 0, 1 c. +1, 0 d. + 1, -1 e. -1, + 1 During the melting of a molecular compound there is no temperature increase because the heat energy is used to a. Increase the velocity of the molecules b, Rearrange atoms within the molecules c, Break covalent bonds within the molecules d. Break attractive forces between molecules Which of the following statements is TRUE? a. An orbital describes the exact path of an electron around a nucleus. b. It is possible to determine the exact location and trajectory of an electron a given point in time, c. it is possible to calculate the wavelength of a moving electron. d. None of these statements is true. What is the net ionic equation for the reaction: Pb(NO_3)_2(aq) + 2 KCl(aq) rightarrow PbCl_2(s) + 2 KNO_3(aq)? a. + NO_3^- (aq) rightarrow KNO_3(aq) b. Pb^2+(aq) + 2Cl^-(aq) rightarrow PbCl_2(s) c. Pb^2+(aq) + 2NO^-_3(aq) + 2K^+(aq) + 2Cl^-(aq) rightarrow Pbl_2(s) + 2K^+(aq) + 2 d.

Explanation / Answer

The options for the first ques arent visible , let me help you out with the next one ...

Ans 7 .d) +1 ,-1

The left resonance structure that has a triple bond in between the carbon and nitrogen atom is more stable due to conjugation .

So the formal charges on the nitrogen atom is +1 and that on Oxygen is -1
