test content\npage 22 of 25\nquestion 22\nwhich of the following is a physical change?\na dissolving metal in hydrochloric acid, hcl\nb shattering a glass bottle of hydrochloric acid, hcl\nc burning a match\nd electrolysis of water (passing an electric current through water to create hydrogen gas and oxygen gas)
Answer
Brief Explanations:
A physical change is one where the substance's chemical composition remains the same. Dissolving metal in HCl is a chemical reaction as new substances are formed. Burning a match and electrolysis of water also involve chemical reactions with new - substance formation. Shattering a glass bottle only changes the physical state (shape) of the glass, not its chemical composition.
Answer:
B. Shattering a glass bottle of hydrochloric acid, HCl
