Write the balanced equation for the half reaction for the single replacement reaction involving iron. This equation considers only the iron cations and the
elemental iron, and it shows how the iron cation (Fe3+) is reduced to become
elemental iron (Fe). How many electrons are represented in this equation? How
does this number of electrons help show a balance of charge on both sides of the
equation? (3 points)

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).
