Answer:
Her numbers are WAY too high. According to the section at the bottom, recycling cans, paper, plastics, etc. is the equivalent of taking 117 cars off of the road. If you took 117 cars off the road for a year, you would only prevent 549.9 metric tons of greenhouse gases all together.

Answer:
True
Explanation:
A titration can be defined as the experiment where the volume of known con concentration is mixed into another solution whose concentration is not known.
Most of the titration are acid-base titration. When performing titration the indicator which is used is usually phenolphthalein. The end point of the titration is the point where the indicator changes its color.
In case of acid base reaction, the end point is achieved when the phenolpthalein turns faint pink in color from transparent.
Hence, the given statement is correct, the indicator changes its color close to the end point of titration.
