Chapter 1, Problem 44P
In 1774 Joseph Priestley isolated a gas that he called "dephlogisticated air." Which of the following observations best shows that dephlogisticated air is an element?
a. Dephlogisticated air combines with charcoal to form "fixed air."
b. Dephlogisticated air combines with "inflammable air" to form water.
c. Dephlogisticated air combines with a metal to form a solid called a "calx."
d. Dephlogisticated air has never been separated into simpler substances.
e. Dephlogisticated air and "mephitic air" are the main components of the atmosphere.

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 this long problem. Thanks
