Nitrogen monoxide reacts with oxygen to give nitrogen dioxide. NO(g) O2(g) > NO2(g) A sample of NO has a volume of 150.0 mL. What volume of O2, in mL, is required to react with it (at the same temperature and pressure)

your answer would be a. 12.5 kg

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
