Although I may not be the smartest, I can definitely answer.
This represents a chemical change because the substances' chemical identities were altered. The fizzing was a clear sign, and the temperature increase was another indicator of the reaction.
The response is:
No, the equation is not balanced. Neither the Nitrogen (N) nor the Hydrogen (H) are in balance!
Here's the reasoning:
⓵ A properly balanced chemical equation means that the quantity of atoms on the reactants side matches that on the products side.
→ The equation lacks balance because there are 2 Nitrogen atoms and 2 Hydrogen atoms on the reactants side. In contrast, on the products side, there is only 1 Nitrogen atom and 4 Hydrogen atoms. Thus, the number of atoms on each side is not consistent!

The molecular formula is C2H6O2
Attached is the solution:
Initially, convert the mass into moles.
Then, divide each mole by the smallest amount to identify the number of atoms in the empirical formula.
Next, calculate the empirical formula mass.
Then, determine the molecular formula by dividing the molar mass by the empirical formula mass.
Finally, multiply the empirical formula by the obtained answer to arrive at the molecular formula of the compound.
