The motor in the lift does 120 000 J of work in 8.0 seconds. Calculate the power output of the motor in the lift.
Use the equation:
Power output
work done
time

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

the answer to this question is 3.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4
