Why was it significant that amino acids were produced from a mixture of methane gas, hydrogen gas, ammonia, and water vapor?
melisa1 [442]

Answer:

It was significant because thanks to Miller's experiment, it was possible to test many years later and with modern techniques, the progress of the evolution of life on Earth.

Explanation:

In Miller's experiment, he subjected a mixture of methane, ammonia, hydrogen, carbon dioxide, nitrogen and water to strong electric shocks and high temperatures. He noted that organic molecules such as glucose, amino acids such as glycine, alanine, glutamic acid and aspartic acid were formed. Subsequently, in 2008 other scientists analyzed these compounds using more sensitive devices. Their analyzes found the formation of 20 amino acids (proteins) and 6 components found in the nucleus of the cells, thus checking the progress of the evolution of life on Earth.

A sample of helium gas has a pressure of 1.20 atm at 22.0 C. At what Celsius temperature will the helium reach a pressure of 2.0
Anarel [89]

Answer: 36.6°C

Explanation:

Given that,

initial pressure of helium (P1) = 1.20 atm

Initial temperature (T1) = 22.0°C

Final temperature (T2) = ?

Final pressure of helium (P2) = 2.00 atm

Since pressure and temperature are given while volume is constant, apply the formula for pressure's law

P1/T1= P2/T2

1.20 atm / 22.0°C = 2.00 atm / T2

Cross multiply

1.20 atm•T2= 2.00 atm•22°C

1.20 atm•T2= 44 atm•°C

Divide both sides by 1.20 atm

1.20 atm•T2/1.20 atm = 44 atm•°C/1.20 atm

T2 = 36.6°C
