Question

Stanley Miller performed an experiment to prove the origin of life. hE took gases $N{H}_3$ and $H_2$ along with

• A. $N_2$ and $H_{2}O$
• B. $H_{2}O$ and $C{H}_4$
• C. $C{H}_4$ and $N_2$
• D. $C{O}_2$ and $N{H}_3$

Answer 1

The correct option is A $N_2$ and $H_{2}O$

The Miller–Urey experiment (or Miller experiment) was a chemical experiment that simulated the conditions thought at the time to be present on the early Earth and tested the chemical origin of life under those conditions.

The experiment used water (H2O), methane (CH4), ammonia (NH3), and hydrogen (H2). The chemicals were all sealed inside a sterile 5-litre glass flask connected to a 500 ml flask half-full of water. The water in the smaller flask was heated to induce evaporation, and the water vapour was allowed to enter the larger flask. Continuous electrical sparks were fired between the electrodes to simulate lightning in the water vapour and gaseous mixture, and then the simulated atmosphere was cooled again so that the water condensed and trickled into a U-shaped trap at the bottom of the apparatus.

So the correct answer is 'H2O and CH4'.
