Answer 2

Step-by-step explanation:

A chemical reaction is one in which a chemical change occurs.

During a chemical change;

• The process is irreversible
• New kinds of matter produced
• There is a change in mass

Based on these premise;

Baking cake batter is a chemical reaction because you cannot reverse the process

Shredding a paper is not a chemical reaction because no new kind of matter is produced.

Twisting of a metal wire is not a chemical reaction

Yellowing of newspaper in sunlight is a chemical change. The process cannot be reversed
