Next, the student calibrates the pipet. The calibrated pipet delivers a mean volume of 49.993 mL with an uncertainty of ±0.006 mL. The student then uses the calibrated 50 mL pipet to deliver a total of 249.965 mL of solution. What is the uncertainty in the delivered 249.965 mL?

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).

Word equation for k(s)+h2o(l) yield koh(aq) + h2(g)
