While boiling potatoes for dinner in salted water, the pot boils over and you notice that the flame on your gas burner turns bright yellow-orange. How would you explain the appearance of a color in the previously blue flame?
Homework Answers
The first reason is blue flame indicates hotter flame while the yellow orange flame indicates cooler flame which is having less temperature due to incomplete combustion of gas.
And the second reason is, you are boiling potatoes in salt water. This salt has Sodium ions in it. When this sodium ions come in contact with the flame, it gives orange yellow colour to flame.
Thus, presence of sodium ions give bright yellow orange flame.

In an Aluminum pot, .15 kg of water at 100 degrees C boils away in 4 minutes. The bottom of the pot is 3.1 x 10^-3 m thick and has a surface area of 0.015 m2 . To prevent the water from boiling too rapidly, a stainless steel plate has been placed between the pot and the heating element. The plate is 1.4 x 10^-3m thick, and it's area matches that of the pot. Assuming that heat is conducted into...

In this experiment, you will measure the rate of photosynthesis
in isolated chloroplasts using the dye 2,6-dichloroindophenol
(DPIP). The transfer of electrons during the light-dependent
reaction results in the production of H+. This H+ ion can reduce
DPIP, changing its color from blue to clear. The color can be
quantitatively measured with a spectrophotometer. However, in this
experiment, you will qualitatively analyze your data.

While at the dermatologist’s office you notice a brochure for a product that promises to erase “crow’s feet” and “frown lines.” You are curious about what this product is and how it works. As you read the brochure you notice it is called Botox and is injected into the facial muscles. BOTOX® Cosmetic, or onabotulinumtoxin A, is only available by prescription. You know that this cosmetic is botulinum toxin, and you remember from your human anatomy & physiology course that...
