Answer:
I think you meant HNO3 + CuCO3 ---> H2O + CO2 + Cu(NO3)2. If so, then the balanced equation would be : 2 HNO3 + CuCO3 ---> H2O + CO2 + Cu(NO3)2
Answer:
The correct answer is option (1).
Explanation:
Mass of the sample = 5.5 g
Percentage of carbon in sample = 35 %
Percentage of oxygen in sample = 100% - 35%

Mass of carbon in a sample: (35%) of 5.5 g

Mass of oxygen in a sample: (100%-35%) of 5.5 g

Entropy is the term defined as a measure of the disorder of a system. This occurs mainly when the thermal energy is not available for the mechanical things.
