Answer:
The mass of the nucleus is almost the same as the atom because a majority of the mass of an atom is stored in the nucleus.
The volume of an atom is larger than the nucleus. The nucleus is a tiny, concentrated area inside of the atom. Atoms are mostly empty space inside.
Explanation:
T1 = 14⁰C = 273 +14= 287 K
T1 = 29⁰C =273 +29 = 302 K
V1 = 4.5 L
P = constant
T1/T2 = V1/V2
287/302 = 4.5/V2
V2= 302*4.5/287 = 4.7L
V2 = 4.7 L
Answer: A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. Two atoms of the same element bonded in a molecule do not form a chemical compound, since this would require two different elements.

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. However, according to this chart, it would get rid of thousands of metric tons of greenhouse gases.
