In order to determine experimentally the specific heat of lead, a student weighs 150.0 g of lead shot. This sample is first heated to 100.0 degrees C, then added to a coffee cup calorimeter containing 35.0 g of water at 20.8 degrees C. The highest temperature observed is 31.0 degrees Celcius.
a) Calculate the specific Heat of the lead (please show work)
b) The theoretical value is 0.128 J/g. degree C. What is the % error?
How do i figure out a mixture of 0.156 moles of C is reacted with 0.117 moles of O2 in a sealed,10.0L vessel at 500 K, producing a mixture of CO AND CO2. the total pressure is 0.640 atm. What is the partial pressure of CO
What is the pH of a solution formed by dissolving 0.100 mol of an acid with a Ka of 1.750x(10 to the -5th) and 0.200 mol of the sodium salt of the same acid in a total volume of 1.000L

A mixture of helium and neon gases is collected over water at 28.0 C and 745 mmHg. if the partial pressure of helium is 368 mmHg, what is the partial pressure of neon?
When 0.170 g of the hydrate CaCl2•xH2O is heated, 0.128 grams of anhydrous CaCl2 remains. What is the value of x in the formula for the hydrate?
A buffer is initially 0.180M in 4-nitrophenol (HC6H4NO3) and 0.200M in potassium 4-nitrophenolate (KC6H4NO3). The Ka of 4-nitrophenol is 3.8*10^-4 and the buffer has a pOH = 3.47. If 0.20g on NaOH were added to 100ml of this buffer what would the ..
