Problem- The mass of KHC8H4O4 is measured to the nearest milligram ; however , the volume of water in which it is dissolved is never of concern. Water is even added to the wall of the Erlenmeyer flask during the titration. Explain why water added to the KHC8H4O4 has no effect on the data , whereas water added to the NaOH solution may drastically affect the data.
Please show me how work it out above problem
An acid solution was standardized against NaHCO3 which was prepared as 75 g NaHCO3 in 1 Liter. Find the Normality of the acid if 28 ml was required to decrease pH to 4.5 if volume of NaHCO3 used in titration was 0.1 Liters.

The streams are labeled as follows: 3 - boiler to turbine 1; 4 - turbine to reheat; 5 - reheat to turbine 2; 6 turbine to condenser; 7 condenser to pump; 8 pump to boiler. Determine the following
A gas sample is known to be a mixture of ethane and butane. A bulb of 200.0 cm^3 capacity is filled with the gas to a pressure of 100.0 x 10^3 Pa at 20.0 degrees C. If the weight of the gas in the bulb is 0.3846 g, what is the mole percent of buta..
Reactant: ethane Product: CCC=CCC It should take 11 steps (1 thing is done 3 times and another is done twice) I think it has something to do with converting it using Alkynes and possibly sp hybridization
