2. In a well-known movie, Raiders of the Lost Ark, there is a famous scene in which the hero tries to outwit the designers of a trap by replacing a gold statue with a bag of sand of about the same volume.
a) Knowing that the density of gold is 19.3 g/mL and sand is 3.1 g/mL, does this seem like a scientifically reasonable plan? Why or why not?
b) In the movie, the hero grabs the gold statue with one hand and appears to handle it quite easily. Given that the volume of the statue appears to be about 1 L, find the mass of the statue.

You exhale co2 which is produced during cellular respiration. co2 combines with the water in your blood's plasma to make up one half of the body's most important buffer pair, carbonic acid. the more physical activity you engage in, the more co2 your body is producing. you can see this by putting some of the cabbage indicator in a glass and then blowing bubbles into it through a straw. can you see a change in the color of the indicator?
