Answer 2

Calculation of the Mass of the Substance

To determine the mass of the substance, we need to consider the mass of carbon dioxide (CO2) and water (H2O) produced during the combustion of the organic substance.

Given: - Mass of organic substance = 2g - Mass of CO2 produced = 4.4g - Mass of H2O produced = 2.4g

To find the mass of the substance, we can subtract the mass of CO2 and H2O from the initial mass of the organic substance:

Mass of substance = Initial mass - Mass of CO2 - Mass of H2O Mass of substance = 2g - 4.4g - 2.4g Mass of substance = -4.8g

However, it is not possible to have a negative mass. Therefore, there might be an error in the given values or calculations. Please double-check the provided information.

Equation of the Reaction with Concentrated Sulfuric Acid

To write the equation of the reaction between the substance and concentrated sulfuric acid, we need more information about the substance itself. Without knowing the specific organic substance, it is difficult to provide an accurate equation for the reaction.

Please provide additional details about the organic substance, such as its chemical formula or name, so that we can assist you further in writing the reaction equation.
