The deprotonation of given terminal alkyne can be done or not by given base has to be determined. Concept Introduction: Acidity of terminal alkynes : Acidity of alkynes depends on pKa of it. Increase in pKa value, decreases acidity of alkynes and vice-versa. During deprotonation of alkynes, if the base added is stronger than it results in formation of weaker base and favors the equilibrium. But the added base produces stronger base, then the acid is weaker acid.

what temperature does a 50% (mole fraction) of ammonia/water liquid mixture boil at 1 atm

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.
