Answer:
The log will float on the water because its density is lower than the liquid, so it will stay at the top due to Archimedes' principle.
Answer:
Gold is a metal, more specifically a transition metal, whereas Oxygen is a nonmetal, more specifically a reactive nonmetal. Using this information, you can compare and contrast metals, nonmetals, and metalloids.
Metals are:
Shiny
High melting point
Mostly silver or gray in color
Mostly solids at room temperature – Mercury (Hg) is a liquid at room temperature
Malleable – able to be hammered into a thin sheet
Ductile – able to be drawn/pulled into a wire
Good conductors of heat and electricity
Nonmetals are:
Dull
Low melting point
Brittle – break easily
Not malleable
Not ductile
Poor conductors of heat and electricity
Metalloids are:
Found on the “zig-zag” line on the Periodic Table of Elements
Have properties of both metals and nonmetals
Can be shiny or dull
Semiconductors – able to conduct electricity under certain conditions

Explanation:
Scientists can use the color of minerals to tell them apart.
Your answer is D. 8
16 = 2^4
72 = 2^3*3^2
So you'll choose 2^3 = 8
