NEETChemistrySome Basic Concepts of Chemistry
Given below are two statements: Statement-I : In the reaction ( CH ₄( ~g )+2 O ₂( ~g ) CO ₂( ~g )+2 H ₂ O ( ~g ) ) One mole of ( CH ₄( ~g ) ) reacts with two moles of ( O ₂( ~g ) ) to give one mole of ( CO ₂( ~g ) ) and two moles of ( H ₂ O ( g ) ). Statement-II (: 1 ~g ) of ( CH ₄( ~g ) ) reacts with 2 g of ( O ₂( ~g ) ) to give 1 g of ( CO ₂( ~g ) ) and 2 g of ( H ₂ O ( g ) ). In the light of the above statements,
Options
- AStatement-I and II both are correct.
- BStatement-I is correct while II is incorrect.
- CBoth Statement-I and II are incorrect.
- DStatement-I is incorrect and II is correct.
Correct answer
B. Statement-I is correct while II is incorrect.
Step-by-step solution
Statement-I: This describes the balanced chemical equatign: (2 O ₂(g) CO ₂(g)+2 H ₂ O ( ) - One mole of ( CH ₄ ) reacts with two moles of ( O ₂ ) to produce one mole of ( CO ₂ ) and two moles of ( H ₂ O ). - Statement-I is correct. Statement-II: This involves incorrect stoichiometry. The masses given do not match the molar masses: - 1 mole of ( CH ₄(16 ~g ), 2 ) moles of ( O ₂ (64 ~g ), 1 ~mole ) of ( CO ₂(44 ~g ) ), and 2 moles of ( H ₂ O (36 ~g ) ). - Statement-II is incorrect. Conclusion: Statement-I is correct
