when you insert a glowing wooden toothpick into a oxygen-filled pipet what would you observe?
a. nothing
b. the glow of the toothpick went completely out
c. heard a gentle pop
d. the glow of the toothpick got brighter and may have reignited.
again Im checking to see if I did this lab right. I observed the toothpick getting brighter but not igniting
I think the answer is d. Note that is says MAY have reignited. If there is enough oxygen it will reignite almost every time.
yay i got that one right :)
Based on your observation, the correct answer would be (d) the glow of the toothpick got brighter and may have reignited. It seems that you did the lab correctly.
To explain why this observation occurred, let's consider the various components involved. When you insert a glowing wooden toothpick into an oxygen-filled pipet, you create an environment where there is an abundant supply of oxygen. Oxygen supports combustion, which is why you observed the toothpick getting brighter.
Typically, a wooden toothpick doesn't burn very well because it contains a small amount of organic material that can be easily consumed by the surrounding oxygen. However, when you introduce an increased level of oxygen into the pipet, the combustion process becomes more efficient, leading to a brighter glow.
It's worth noting that the toothpick may not have fully ignited because it requires sustained heat to continue burning. The limited surface area of the toothpick and the brief time it was in contact with the increased oxygen may not have generated enough heat to sustain ignition.
Overall, your observation of the toothpick getting brighter but not igniting aligns with the expected outcome in this experiment.
