Bromination of (z)? 3? hexene yields racemic 3,4? dibromohexane. provide a detailed mechanism for formation of the (3s,4s)? enantiomer, specifically showing br2 addition occurring from the top face of the alkene.

At 300 mm hg, a gas has a volume of 380 l, what is the volume at standard pressure

What is a substance? a. a physical property of matter b. a chemical property of matter c. an element or compound that cannot be physically separated d. characteristics used to tell the difference between mixtures

Butane gas reacts with oxygen gas to give carbon dioxide gas and water vapor (gas). if you mix butane and oxygen in the correct stoichiometric ratio, and if the total pressure of the mixture is 390 mmhg, what is the pressure (in mmhg) of water vapor after the reaction is completed (temperature and volume do not change).
