which of the following is not an example of real - world applications of chemical reactions?\na. formation of rust on metal\nb. melting of ice\nc. combustion in a car engine\nd. baking bread
Answer
Brief Explanations:
A chemical reaction results in the formation of new substances with different chemical properties. Rust formation on metal is a chemical reaction between iron, oxygen, and water. Combustion in a car engine involves fuel reacting with oxygen to produce energy and new substances. Baking bread includes chemical reactions like yeast - induced fermentation. Melting of ice is a physical change (from solid to liquid), not a chemical reaction as the water molecules remain the same chemically.
Answer:
B. Melting of ice
