Explain how much energy is released when 6.03g of liquid water 60.00 degrees Celsius is frozen at -1.00 degrees Celsius?
what is the concentration (in mole/L or M) of Cu2+ and NO3- in the final solution. Remember your significant figures. If there is an impurity of Cu2+ in the water you are using to perform the dilutions, what type of error is this associated with t..
Explain what is meant by Chousekeeping gene and why the gene for enolase is not considered a housekeeping gene despite it being expressed in all tissues.
