During a class demonstration, a model volcano “erupts” when the teacher adds vinegar to baking soda inside the volcano. Vinegar contains acetic acid, and baking soda is sodium hydrogen carbonate. When they are combined, a reaction occurs and bubbles form. Which gas is in the bubbles, and why do the bubbles form? A. Oxygen gas forms because an acid reacts with a metal. B. Carbon dioxide gas forms because an acid reacts with a metal. C. Oxygen gas forms because an acid reacts with carbonate ions. D. Carbon dioxide gas forms because an acid reacts with carbonate ions.

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
