Question 12
The gases labelled X and Y are A. chlorine oxygen B. oxygen chlorine C. chlorine hydrogen D. hydrogen chlorine
Worked Solution & Example Answer:The gases labelled X and Y are A - VCE - SSCE Chemistry - Question 12 - 2007 - Paper 1
Step 1
Identify the Correct Pair of Gases
Answer
The question presents four options for the gases labelled X and Y. To answer this question correctly, we need to recognize the common pairing of gases based on their chemical properties.
From the options given:
- (A) chlorine and oxygen
- (B) oxygen and chlorine
- (C) chlorine and hydrogen
- (D) hydrogen and chlorine
When examining these combinations, option C (chlorine and hydrogen) is particularly notable. Chlorine (Cl) reacts with hydrogen (H) to produce hydrogen chloride (HCl), which indicates they can be a pair in chemical reactions. Hence, based on the marking scheme indicating option C as the correct answer, we deduce that gases X and Y are chlorine (X) and hydrogen (Y).
