If a given forward reaction is exothermic and the reactants and products in a flask initially are at equilibrium, what will happen when the temperature is raised?

A. The system will shift to the right (in the direction of the forward reaction).
B. The system will shift to the left (in the direction of the reverse reaction).
C. The system will not shift.
D. The rates of both the forward and reverse reactions immediately decrease.

What type of reaction is shown below? check all that apply. 2h2o2 → 2h2o + o2 synthesis decomposition combustion

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
