When Vernier readings (degree) were plotted on y-axis, and wavelengths of line-spectra (nm) for Hg-lamp were plotted on x-axis, the best-fit-line equation obtained from Excel was y = 0.204x + 131.5 Predict where (on the Vernier reading) you may find the faint purple line in Hg-lamp, which was very challenging to find in this lab.

213.9°

Explanation:

The faint purple line in Hg-lamp falls around 404 nm.

Corresponding Vernier reading based on the best fit line equation is given by substituting for 404 nm for x in the above equation

y = 0.204(404) + 131.5

= 213.9 degrees

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.
