Answer:
An ambident ("both teeth") group is a group that can attach to another by either of two atoms. A nitro group can bond through either N or O. In organic chemistry, this property gives rise to functional group isomers.

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

Answer:
94.44
Explanation:
Volume is equal to Mass/Density so therefore, you do the mass which is 68.0 g/0.72 g/mL which is the density and get 94.44 mL because the g cancel each other out when it comes to the label!
Answer:
The partial pressure of oxygen is 52 kPa.
Explanation:
We apply Dalton's law, according to which the sum of the partial pressures of the gases that make up a gaseous mixture is equal to the total pressure of this:
Ptotal = P N2 + P C02 + P 02
300 kPa= 200kPa + 48 kPa + P 02
P 02= 300 kPa - 200kPa - 48 kPa= <em>52 kPa</em>
