For the reaction of ethylene represented above, delta H is - 1,323 kJ. What is the value of delta H if the combustion produced liquid water H2O(l), rather than water vapor H2O(g)? (delta H for the phase change H2O(g) -> H2O(l) is -44 kJ mol-1.)

Asample of freon gas has a volume of 2.23 liters, a pressure of 4.85 kpa, and a temperature of -1.36°c. calculate the volume at a pressure of 1.38 kpa and a temperature of 5.5°c. (show work)

Ab c or d ? i’m not sure what the answer is

2-bromo-2-methylbutane undergoes an e1 elimination reaction in the presence of ethanol. in the next reaction only one of the possible products is represented. although the product shown is not the major product of the reaction, notice that there is more than one way it can be produced. complete the mechanism and draw the missing substances.
