Our solar system is thought to have started with the birth of our Sun, which formed from a cloud of interstellar dust and gas. T

his cloud condensed and eventually collapsed from its own gravitational pull. The heat and pressure built up, forming a protostar. Eventually nuclear fusion began. Planets formed from remaining dust and gas orbiting the protostar.
This explanation best describes _____.
the nebular theory
the big bang theory
the inflation theory
the condensation theory

The formation of protons over neutrons (thus producing about a 7:1 ratio) was favored in the early universe because:____.
tatiyna

Because it requires more energy to create a neutron from a proton than it does to create a proton from a neutron, protons were formed more frequently than neutrons in the early universe. The correct answer is option b.

To find the answer, we need to know more about the early universe.

<h3>How the formation of proton over neutrons was favored in the early universe?</h3>
  • A neutron is produced with greater energy than a proton.
  • However, later on, some of the protons were changed into neutrons.
  • Contrary to some claims, the proton is a stable particle that never decays, but the neutron is unstable outside of the nucleus and decays with a half life of around 10.5 minutes.
  • However, very few would have had time to decay on the timeline you mention in your question.
  • Every matter particle should have been accompanied by an antimatter particle, and every proton, neutron, and electron, by an anti-neutron and a positron, respectively.
  • Where did all the antimatter go is the great mystery. There have been a few attempts to explain this, but they have failed.

Thus, we can conclude that, the correct answer is option b.

What is the volume of a balloon of gas at 842 mm Hg and -23° C, if its volume is 915 mL at a pressure of 1,170 mm Hg and a tempe
garik1379 [7]
Answer:
             V₂  =  1070 mL or 1.07 L

Solution:

Data Given;
                  P₁  =  1170 mmHg

                  V₁  =  915 mL

                  T₁  =  24 °C  +  273 K  =  297 K

                  P₂  =  842 mmHg

                  V₂  =  ?

                  T₂  =  - 23 °C  +  273 K  =  250 K

According to Ideal gas equation,

                       P₁ V₁ / T₁  =  P₂ V₂ / T₂

Solving for V₂,

                       V₂  =  P₁ V₁ T₂ / P₂ T₁

Putting Values,

                       V₂  = (1170 mmHg × 915 mL × 250 K) ÷ (842 mmHg × 297 K)

                       V₂  =  1070 mL or 1.07 L

patriot [66]

<u>Answer:</u>

Law used: Combined Gas Law

<u>Explanation:</u>

We are given the following problem:

Carbon dioxide is in a steel tank at 20°C, 10 liters and 1 atm. What is the pressure on the gas when the tank is heated to 100°C?

To solve this, the most appropriate law that can be used it Combined Gas Law, which is the result of combining the Boyle's law, Charles' law, and Gay-Lussac's law together.
