Achemist measures the amount of oxygen gas produced during an experiment. she finds that 4.87 g of oxygen gas is produced. calculate the number of moles of oxygen gas produced. be sure your answer has the correct number of significant digits.

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).

Electric charge is what ? a. kinetic energy b. radiation c. discovery d. electricity
