Chapter 4, Problem 69E
A 25.0-mL sample of a 1.20 M potassium chloride solution is mixed with 15.0 mL of a 0.900 M barium(II) nitrate solution and this precipitation reaction occurs:
2 KCl(aq) + Ba(NO3)2(aq) → BaCl2(s) + 2 KNO3(aq)
The solid BaCl2 is collected, dried, and found to have a mass of 2.45 g. Determine the limiting reactant, the theoretical yield, and the percent yield.

1) Suppose 0.1 kg ice at 0°C (273K) is in 0.5kg water at 20°C (293K). What is the change in entropy of the ice as it melts at 0°?
To produce the original "water gas" mixture, carbon (in a combustible form known as coke) is reacted with steam: 131.4 kJ + H20(g) + C(s) → CO(g) + H2(g) From this information and the equations in the previous problem, calculate the enthalpy for the combustion or carbon to form carbon dioxide.
kindly show me how to solve both parts of the same long problem. Thanks
we were assigned to dilute 900ppm
in to 18ppm by using only 250ml vol
flask. firstly we did calc and convert
900ppm to 0.9 ppm to dilute in 1 liter.
to begin the experiment we took
0,225g of kmno4 and dissolved in to
250 vol flask. then further we took 10
ml sample sol and dissolved in to 100
ml vol flask and put it in to a
spectrometer and got value of 0.145A
.
upon further calc we got v2 as 50ml
. need to find DF, % error (expval and
accptVal), molarity, molality. please
write the whole report. thank you
