Answer:
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
Answer :
The complete equation for the reaction of sulfuric acid and sugar is,
By the stoichiometry of the reaction,
1 mole of sucrose react with the 11 moles of sulfuric acid to give 12 moles of carbon and 11 moles of water.
In this reaction, sulfuric acid react with sucrose (sugar). It dehydrates the sugar molecules which means it eliminates the water.
Molar mass of FE2O3=2(55.85)+3(16)=159.7
2.56g*1mol/159.7*2mol/1mol*55.85g/1mol=1.79g
I know CL is chlorine and NA is sodium.
I believe the answer is D, but not 100%
