It's a two-step process:
1) Sugar (sucrose) is broken down into two molecules of glucose.
C12H22O11 + H2O + invertase----> 2C6H12O6
2) The two glucose molecules are broken down into ethanol and carbon dioxide.
2C6H12O6 + Zymase ----> 4C2H5OH + 4CO2

Dissolution is usually considered a physical reaction, although weak chemical bonds between the solute and solvent may exist in the solution.
No, dissolving sugar in water is a physical property because it does not change the chemical composition of either the sugar or the water. The process involves breaking the intermolecular forces between sugar molecules, allowing them to mix with water molecules.
The separation of sugar crystals from a sugar syrup by evaporating water is a physical process, not a chemical reaction. This is because no new substances are formed during the process—the sugar molecules remain the same whether in the syrup or as crystals.
Yes, browning sugar in a frying pan is a chemical reaction known as caramelization. It involves the breakdown of sugar molecules at high temperatures, resulting in the formation of new compounds that give the characteristic brown color and flavor.
Sugar dissolving in water is a chemical change because sugar is Sucrose which in aqueous solution is broken down into Glucose and Fructose.
Dissolution is usually considered a physical reaction, although weak chemical bonds between the solute and solvent may exist in the solution.
The chemical formula (not reaction) of sucrose is C12H22O11.
No, dissolving sugar in a cup of tea is a physical change, not a chemical reaction. The sugar molecules are simply mixing with the tea molecules to form a homogeneous solution. Chemical reactions involve the breaking and forming of bonds between atoms.

One evidence that burning sugar is a chemical reaction is the production of heat and light during the process. This indicates a change in the chemical composition of the sugar molecules as they react with oxygen in the air, releasing energy in the form of heat and light. Additionally, the formation of new substances such as carbon dioxide and water from the sugar molecules further supports the occurrence of a chemical reaction.

There is no chemical reaction. In maple syrup the sugar is dissolved in water. When the water evaporates the sugar comes out of solution and forms crystals.
This reaction is a chemical process.
No, it is a physical change. A chemical reaction involves changing a molecule(s) into something else. When dissolving sugar in water, you still have sugar and you still have water.
