It is believed that water must be present for life to exist. The moon has no atmosphere and the surface temperature ranges from 100 degrees C during the day to -175 C at night. If water exists on the moon, it must exist as a solid or liquid. Water in its gas state on the moon would float away into space since the moon has no atmosphere, Based on these conditions and the phase diagram of water, predict whether water exists on the moon. Give reasons, Include in your answer a statement about the atmospheric pressure on the moon. Draw the phase diagram of water and put a on the phase diagram to show the pressure and temperature conditions in the day and at night on the moon.
Benzene has a boiling point of 80.1 degrees celcius and a molal boiling point elevation constant of 2.53 degrees celcius/m. Calculate the boiling point of a solution containing 15.0 g of the non-electrolyte C6H4Br2 in 125 ml of benzene (sp gravity..

The half-equivalence point of a titration occurs half way to the end point, where half of the analyte has reacted to form its conjugate, and the other half still remains unreacted
How many joules of heat could be produced from a 170 calorie package of crackers
When adding the solution of HNO3 from the buret in Step 14 to beaker 4, you know that you added 2.5 mL instead of 1.5 mL for a total volume of 11.0 mL. How would the calculated value of the equilibrium constant be affected for this sample?
A buffer solution is prepared by mixing 47.5 mL of 0.772 M carbonic acid with 58.8 mL of 0.0346 M sodium hydrogen carbonate. 1. Calculate the pH (to two decimal places) of this solution. Assume the 5% approximation is valid and that the volumes are a..
