Составьте уравнения соответствующих реакций.

Which of the following molecule(s) have lone pair electrons and/or non-identical central bonds? \( \mathrm{CCl}_{4} \) \( \mathrm{CHCl}_{3} \) \( \mathrm{SO}_{3} \) \( \mathrm{CO}_{2} \mathrm{O} \)

Please select the molecule(s) with resonance structures from the following. CCl 4 CHCl 3 SO 3 H 2 O None

\[ \mathrm{Fe}_{2} \mathrm{O}_{3}(\mathrm{~s})+2 \mathrm{Al}(\mathrm{s}) \rightleftharpoons \mathrm{Al}_{2} \mathrm{O}_{3}(\mathrm{~s})+2 \mathrm{Fe}(\mathrm{s}) \] View Available Hint(s) The equilibrium will shift toward the reactants. The equilibrium will shift toward the products. The reaction will not shift toward either the products or reactants. The reaction will shift toward both the reactants and products.

If an endothermic reaction is at equilibrium, how will the equilibrium shift when heat is added to the reaction? View Available Hint(s) The reaction will shift toward the reactants. The reaction will shift toward the products. The reaction will not shift toward products or reactants. The reaction will shift toward both reactants and products.

Please select polar molecule(s) from the following. \( \square \mathrm{CCl} 4 \) \( \square \mathrm{CHCl} 3 \) \( \square \mathrm{CO} 3 \) CO 2
