The temperature of 150 mL of water is 25°C. What must happen for the temperature of the water to increase to 35°C?
A. Water must be removed to decrease the thermal energy.
B. Thermal energy must be transferred from the water to decrease
the average kinetic energy of the water molecules.
C. More water must be added to increase the thermal energy.
D. Thermal energy must be transferred to the water to increase the
average kinetic energy of the water molecules.

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.
