Stanley Miller and Harold Urey performed and experiment by recreating in the laboratory the probable conditions of the atmosphere of the primitive earth. For how long was the experiment run continuously? Name two products formed.

Explanation

**Step-by-Step Solution:**

1. **Identify the Experiment**: The experiment conducted by Stanley Miller and Harold Urey is known as the Miller-Urey experiment. It aimed to recreate the conditions of the primitive Earth to investigate the origin of life.

2. **Duration of the Experiment**: The experiment was run continuously for a period of **one week**. This duration was essential to allow the chemical reactions to occur and for the products to form.

3. **Conditions Used**: In the experiment, Miller and Urey used a mixture of gases that were believed to represent the early Earth's atmosphere, including methane (CH₄), ammonia (NH₃), hydrogen (H₂), and water vapor (H₂O). They also provided energy in the form of electric sparks to simulate lightning, which was thought to be a source of energy on the primitive Earth.
