Question

An experimenter is testing different gasses for possible reactivity with each other by mixing them in a water-filled tube. For each observation listed below select the statement that best describes whether or not it indicates a chemical reaction has taken place. The total volume of gas increases by the volume of added gas. There are no other changes. no evidence of a reaction. The total volume of gas decreases after the second gas is added. There are no other changes. evidence of a reaction The total volume of gas increases by the volume of added gas but the gas after mixing has a color the neither individual gas has. There are no other changes. The total volume of gas increases by the volume of added gas. An acid-base indicator added to the water changes color where the gas is in contact with the water. The total volume of gas increases by less than the volume of added gas. There are no other changes. Which of the following are typical observations made in Part 1C of Chemical

Explanation / Answer

Soln 1 - When two gases are mixed, does it A) No evidence of reaction or B) evidence of reaction

A : Total volume increases. No other change

B : Total volume decreases. No other change

B : Total volume increases. Solution develops a color that none of the gases had

A : Total volume increases. Acid-base indicator gives color to solution

B : Total volume increases by value less than the volume of gas added

Soln 2 - For the reaction in atmosphere, oberservations,

- Nitrogen and oxygen does not react

- Nitrogen does not appreciably dissolve in water

Soln 3 - For the experiment of NO(g) added to O2(g),

- As NO(g) is added, the volume of Oxygen in measuring tube decreases
