Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

3. How would you expect the density of the gummy bear to change if vOu soakod it in

Expert Solution

Step 1

Density does not depend upon amount of substance used thus is an intensive physical property which is calculated by dividing mass by volume and is formulated as

$ρ (density) = \frac{m (mass)}{V (volume)}$

Keyon and Jarred performed the following experiment: A piece of magnesium was placed on a watch glass; the watch glass and magnesium together weighed 2.00 g. They burned the magnesium and it produced bright light, smoke, heat and a white residue. They then weighed the white residue on the watch glass. Watch glass with residue weighed 2.25 g. From this information, they reached separate conclusions: 1 Keyon: The magnesium gained mass, but it was due to some type of problem with their measurements. Jerrod: The extra mass had to come from the oxygen in the air; burning something always means it combines with oxygen. Which student has the best explanation for the gain in weight and why? Keyon because the experiment should be done several times to make sure they are getting accurate measurements. Jerrod is correct because oxygen in the air added mass, by…
