For many purposes we can treat ammonia (NH) as an ideal gas at temperatures above its boiling point of – 33. °C. Suppose the temperature of a sample of ammonia gas is raised from 85.0 °C to 121.0 °C, and at the same time the pressure is
increased by 15.0%.
increase
Х
Does the volume of the sample increase, decrease, or stay the same?
decrease
O stays the same
If you said the volume increases or decreases, calculate the percentage change in 0%
the volume. Round your answer to the nearest percent.

Asolution is made by dissolving 25.5 grams of glucose (c6h12o6) in 398 grams of water. what is the freezing point depression of the solvent if the freezing point constant is -1.86 °c/m? show all of the work needed to solve this problem.

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
