Answer:
The answer is below
Explanation:
The density of an object is its mass per unit of volume. Dense objects feel very heavy for their size, while for objects with low density they are very light for their size.
Density is the ratio of mass to volume; it is given by:
Density (D) = mass (m) / volume (V)
An object sinks in water if the density of the object is greater than the density of water. While an objects floats on water if the density of the object is les than the density of water
Answer:
(a) CH₃CH₂CH₂CH₂CH₂OH
(b) CH₃OH
(c) CH₃CH₂CH₂CH₂CH₂OH
Explanation:
In alcohols, the -OH group is responsible for the polarity. The longer the non-polar hydrocarbon chain, the less polar is the compound.
Regarding solubility, we will consider the general rule "like dissolves like", meaning polar is soluble in polar and non-polar is soluble in non-polar.
(a) I₂ is non-polar, so it will be more soluble in the least polar solvent, which is pentanol (CH₃CH₂CH₂CH₂CH₂OH).
(b) NaCl is an ionic compound, that is, there is a big difference in electronegativity between the atoms. Then, it will be soluble in the most polar alcohol, methanol (CH₃OH).
(c) Pentane (CH₃CH₂CH₂CH₂CH₃) is non-polar, so it will be more soluble in the least polar solvent, which is pentanol (CH₃CH₂CH₂CH₂CH₂OH).
Volcanic islands, seamounts, guyouts
Explanation:
The magma rising from this type of plate movement may produce under water volcanic activities.
The magma here would be mafic - ultramafic because it is produced from melting of oceanic plates.
As the subducting oceanic plate melts and begins to rise, it will settle and cool on the ocean floor resulting in the formation of massive and extensive seamounts.
With time, they outgrow the ocean level and forms volcanic Islands.

You should test several properties because some minerals might be similar, but if you test all the properties, you will identify it correctly.
