Answer:
Argon
Explanation:
The element that would most likely be a good substitute for neon is "argon".
These two elements belong to the noble gases in Group 18(8A) of the Periodic Table. They are inert gases - they do not react chemically with other substances.
Argon, as an inert gas is often used whenever an inert atmosphere is needed. Argon is used in incandescent light bulbs. It is used to stop oxygen from corroding the filament. It is also used by welders to protect weld area.
Argon is a good substitute for neon in this context because they possess some physical properties which are similar.
Answer:
0.24 g/mL
Explanation:
The density of an object is given by the ratio between its mass and its volume:
where
m is the mass of the object
V is its density
In this problem, we have:
m = 7.0 g is the mass of the object
The volume of an irregular shaped object can be measured by putting it into water, and by measuring the difference in water volume.
In this case,
is the initial volume of water
is the final volume of water
So the volume of the object is
Therefore, the density of the object is:
