The granite statue of a hero in the local park is discolored. Your friend suggests that the rain will clean the statue. Do you agree? Explain your response

No because the statue is discolored from weathering.

Explanation:

Since the statue was already discolored, that means the substance has been acted upon by a process known as weathering .

Weathering is the breaking down of rocks or dissolving of rocks by the action of rain water, biological activities and temperatures changes. Weathering may be mechanical or chemical . Mechanical weathering live no changes in the overall chemical change of the weathered rock.

Chemical weathering usually occurs when rain water reacts with mineral constituent of rock to form a new minerals like clay and soluble salt. The Chemical changes can be more rapid if the rain water is slightly acidic. The rainwater in the presence of oxygen(oxidation),  because of it acidity may have caused the discoloration of the granite rock. Rain water will likely promotes weathering not the other way round

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

yes
