Using the data on a seperate page for the determination of heat of nuetralization extrapolate to the mixing time, determine the intial and final temp for the solutions. 50mL of 2.0M HCL and 2.02M NaOH were mixed and the heat neutralization was determined by plotting temperature in degrees C as a function of time for 8 minutes . Assume that the density of the solution is about 1.0g/mol. The following are heat of formation , kJ/mol for HCl(-164.4), NaOH(-469.6) NaCl (-407.1) and water (-285.9) the specific heat capacity of water is 4.184J/gK and that of 1.00M NaCl is 3.89 J/gK. The mass of the solution was 103.00g.
A. Determine the experimental and theoritcal heats of neutralization per mol water formed.
B. Calculate the percent error.
Initially a container contains 0.46 M HI and no product. What is the equilibrium concentration of H2
Calculate the pH at the equivalence point for the titration of 0.170 M methylamine (CH3NH2) with 0.170 M HCl. The Kb of methylamine is 5.0× 10-4.
Its volume is 2.0 x 10^2 mL and its pressure is 750 torr. what is the molar mass?
What is the pH of a 0.175 mol/L solution of sodium acetate, CH3COONa, at 25oC? (pKa=4.74 at 25oC for CH3COOH.) Give your answer accurate to two decimal places
A major source of iron is from the mineral magnetite which is 72.4% iron by mass. If magnetite has a density of 5.20 g/cm3, how many cubic meters
Determine the minimum concentration of the precipitating agent on the right to cause precipitation of the cation from the solution on the left.
A piece of metal weighing 10.0g is raised in tempreture from 25 C to 76.5C. it is found that it absorbed 47.6 calories of heat in the process.
The standard Gibbs-free energy of a system is related to its equilibrium constant through the following equation.
CO 5) What should be the coefficient of hydrogen, H2, in the following equation in order to make it balanced? 2 Al + 3 H2SO4 ---> Al2(SO4)3 + ? H2

When the reaction 2 H2S g ~ PCl3 + Cl2 is carried out at 1065 degrees celcius, Kp = 0.012. Starting with pure H2S at 1065degrees, what must the initial pressure of H2S be if the equilbrated mixture at this temperature is to contain 0.250 atm of H2..
The initial temp of the calorimeter is 21.5 degrees celcius. the H2o is initially 98.1 degrees celcius and final temp of both the H2o and calorimeter is 39.2. Calculate the heat capacity in units of J/c. Use 4.184 j/g for specific heat of water
