Calculate the ph of the buffer after the addition
A buffer is made up of 355 mL each of 0.200 M NaHCO3 and0.134 M Na2CO3. Enough water is added to thebuffer to make the total volume 10.0 L. Calculate the pH of the buffer after the addition of 0.0300 mol of HCl to 0.710 L of diluted buffer.

A sample oxygen is collected over water and has a volume of7.84 ml. The pressure od the collected "wet" gas is 71.8 KPa andthe temperature is 20°C.
The joint distribution of a proportion of votes for candidate X and a proportion of votes for candidate Y is given by fx,y(x,y)=1, 0<=x<2, 0<=y<=1, 2y<=x.
Compute the entropy production and the exergy (work) loss due to the exchange of heat across a finite temperature difference. The heat exchanger shell is perfectly insulated.
Plot a curve of the specific exergy of 1 kg of a substance that has a constant specific heat of 1 kJ/kg-K over the temperature range -100°C to +1000°C
If the number of people that voted for the candidate in the sample is 0, do you think that this could be used as a proof to contradict the candidate's pronostic? Back your claims with quatitative information.
