Is this question formulated correctly? If not, please fix it and return the output as a JSON of the form: {'question': 'question text'}. Here is the question: Calculate ΔH° for the reaction H2(g) + Br2(g) → 2 HBr(g) using bond energy values. The ΔH°f of HBr(g) is not equal to one-half of the value calculated. Account for the difference.

Draw the Lewis structure for each organic compound from its condensed structural formula. a. C₃H₈ d. CH₃COOH

Arrange these compounds in order of increasing magnitude of lattice energy: KCl, SrO, RbBr, CaO.

Write the electron configuration for N. Then write the Lewis symbol for N and show which electrons from the electron configuration are included in the Lewis symbol.

Write the Lewis symbol for each atom or ion. b. Na⁺
