Sometimes in lab we collect the gas formed by a chemical reaction over water (see sketch at right). This makes it easy to isolate and measure the amount of gas produced. Wala Suppose the H, gas evolved by a certain chemical reaction taking place at 40.0 °C is collected over water, using an apparatus something like that in the sketch, and the final volume of gas in the collection tube is measured to be 80.0 mL. Sketch of a gas-collection...

This makes it easy to isolate and measure the amount of gas produced. gas water chemical reaction Suppose the CO gas evolved by a certain chemical reaction taking place at 40.0 °C is collected over water, using an apparatus something like that in the sketch, and the final volume of gas in the collection tube is measured to be 147. mL....
The hydrogen gas formed in a chemical reaction is collected over water at 30.0 ℃ at a total pressure of 732 mm Hg. a) What is the partial pressure of the hydrogen gas collected in this way? b) If the total volume of gas collected is 720 ml, what mass of hydrogen gas is collected?
The hydrogen gas formed in a chemical reaction is collected over water at 30.0 ∘C at a total pressure of 728 mmHg . Part A What is the partial pressure of the hydrogen gas?
The hydrogen gas formed in a chemical reaction is collected over water at 30.0 ∘C at a total pressure of 728 mmHg . If the total volume of gas collected is 724 mL , what mass of hydrogen gas is collected?

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
