At 298 K and 1 bar pressure, the density of water is 1.00 , and C=75.3J K^-1 mol^-1. The change in volume with temperature is given by delta V=Vinitial*beta delta T , where beta, the coefficient of thermal expansion, is .2.07*10^-4 K^-1. Part A If the temperature of 347g of water is increased by 22.7K , calculate w.Part B If the temperature of 347g of water is increased by 22.7K , calculate q.Part C If the temperature of 347g of water is increased by 22.7 K, calculate Delta H.Part D If the temperature of 347g of water is increased by 22.7K , calculate Delta u.

Calculate the change in pH when 7.00 mL of 0.100 M HCl(aq) is added to 100.0 mL of a buffer solution that is 0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq).
HbS has normal shape under normal conditions, but under conditions of low [O2] the hemoglobin forms fibrous aggregations, giving the entire red blood cell a sickle shape. (See image of eight HbS molecules at right.)
Compare the relative rate of the foward (EtOH as a substrate) and back reaction (with acetylaldehyde). Use the Michaelis-Menten equation to solve for v when ethanol is 99mM and acetylaldehyde is the substrate and its concentration is 1mM
A mixture of three gases has a total pressure at 293K of 1380 mmHg. The mixture is analyzed and is found to contain 1.27 mol CO2, 3.04 mol CO, and 1.50 mol Ar. What is the partial pressure of Ar?
