Hey! In order to answer this question, we need to understand the difference between mass and density. Mass is the property of matter that measures its resistance to its acceleration, while density is the measure of mass per volume.
Mass is independent as it just focuses on how heavy an object is while density isn't. It can be represented by this equation.
Density = Mass/Volume
If the iron block has more mass per volume than the gold. Then you can consider that the iron has a higher density than gold. However, only if both have the same amount of volume. If there is less or more, then it can fluctuate.
We have that, the skin has pigment that protects from the sun(Melanin) but excess <em>exposure </em>can still cause serious damage.
<h3>Solar
Energy</h3>
Generally, Sunlight exposures can be a double edge sword as it provides one of the essential vitamins needed by the body to thrive(vitamin D), anon the other hand it still holds Heat energy which exess exposure to can cause ones burns and destruction
Therefore
We say that over heating by sunlight can damage lots of things from skin, set fires. The skin has pigment that protects from the sun(Melanin) but excess exposure can still cause serious damage.

Answer:
Options B and C
Explanation:
Let's take a look at the options and get our answer by way of elimination. The basic definition of a neutral solution is given as;
A neutral solution is a substance which is neither acid nor basic . it has a PH of 7. it will have equal amount of H+ AND OH- ions in it.
a) a neutral solution does not contain any H3O+ or OH- This is wrong because take water as an example, it is neutral but contains both ions.
b) a neutral solution contains [H2O] = [H3O+]. This option is correct cause it is in line with the definition above.
c) an acidic solution has [H3O⁺] > [OH⁻]. Acidic solutions are any solution that has a higher concentration of hydrogen ions than water. This option is correct.
d) a basic solution does not contain any H3O⁺. This option is wrong. Basic solutions are any solution that has a higher concentration of hydroxide ions than water. This means they contain H3O⁺ but [OH⁻] is greater.
