Answer 1

S+O2 -> SO2
SO2 + H2O -> H2SO3

То есть данный элемент является серой ;)

Answer 2

Element E in the Transformation Scheme E → EO2 → H2EO3

The given transformation scheme involves the element E, which undergoes two successive transformations: E → EO2 and EO2 → H2EO3. Let's break down each step of the transformation and explore the possible elements involved.

Step 1: E → EO2 In this step, the element E is transformed into EO2. Unfortunately, the specific element E and the details of this transformation are not provided in the question. Therefore, it is difficult to provide a precise answer without more information.

Step 2: EO2 → H2EO3 In the second step, EO2 is further transformed into H2EO3. Again, without additional information, it is challenging to determine the exact elements involved in this transformation.

To provide a more accurate answer, please provide more details about the specific elements or compounds involved in the transformation scheme.
