entropies of atom combination to determine if any of the following reactions have an equilibrium constant greater than 1. Find the reaction with the greatest equilibrium constant. Find the reaction with the smallest equilibrium constant.
Since heat is an extensive property, the amount of heat that is produced depends on the amount of reactants utilized in the reaction. If you have more reactant then you will have more heat. Just think of a big fire cracker versus a small fire crac..
The methyl benzoate and acetanilide react with HNO3, H2SO4, and glacial acetic acid. Need to know the possible products and then the one that actually forms.
a 27.7 sample of CO2(g) was collected over water at 25 degree celcius ans 1atm.What pressure due to CO2(g) (the vapour pressure of water at 25c is 23.8 torr? what will the volume be of CO2 be at the same temp and pressure after removing the water ..
A gas is heated from 269 K to 283 K while its volume is increased from 21.5 L to 37.0 L by moving a large piston within a cylinder. If the original pressure was 1.10 atm, what would be the final pressure?
Describe in detail how you would prepare a solution with a concentration near 0.10 M from a 0.650 stock solution. Calculate the final concentration of the diluted solution. It should be within 10% of 0.10 M
