A chemist collected 56.1 mL of gas in an open manometer. The next day, the chemist noted that the volume had changed to 57.9 mL and the barometer reading was 99.4 kPa. The temperature had not changed. What had been the barometer reading on the previous day when the gas was collected?

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

it is stable as it is in group 0 which have full outer shells of electrons
