called com
(a) slunch the experimental set-up.
() ploe the volume of hydrogen gas collected
a t the time taken
c) saan the time taken for the reaction to rea
completion
(2) expathe gradual decrease of the reaction
(6) why did the student stop taking readings
a ncond intervals after 30 seconds?
explain the importance of taking readings
n o successive readings agree.
on the same axes, sketch and explain the
one that would be obtained at
a higher temperature.
6) lower acid concentration

For questions 1 and 2, consider the following experimental data.hydrogen emission lines were detected at the following wavelengths (in nm): 121.6102.697.395.093.8question 1use the electromagnetic radiation classifications below and figure 1-1 in the introductory information for this lab (in the lab manual) to determine the nf value for the experimental data provided? wavelength, ?
