Chemistry
1 answer:
liubo4ka [24]3 years ago
3 0

Answer:

The correct approach will be "Increased gravitational attraction".

Explanation:

  • The increased gravitational attraction seems to be the natural or physical phenomenon that is required to promote nuclear reactions including star formation.
  • This is much more important to establish stars at different temperatures (lower) and greater magnetic pull as well as nuclear fusion tends to happen.

How does evolution work
sergey [27]
Billions of years ago, according to the theory of evolution, chemicals randomly organized themselves into a self-replicating molecule. This spark of life was the seed of every living thing we see today (as well as those we no longer see, like dinosaurs). That simplest life form, through the processes of mutation and natural selection, has been shaped into every living species on the planet.

How do you think we could solve the problem of plastic pollution in our oceans?
Juliette [100K]

Answer:

Starting from your own home is the best way to reduce plastic pollution. You can reduce it by stop using plastic bags, water bottles, anything that is plastic. You can reuse things instead. Use less energy. Turn off the lights whenever you leave the house or if you aren't using it. Lastly, conserve water. Don't let the water running if you aren't using it.

Hope this helps! :)

Calculate the pressure in atm, if 0.00825 moles occupies 174 mL at -15 celcius.
Vlad [161]
Answer is: <span>the pressure is 1.12 atm.
</span>n(O₂) = 0.00825 mol, amount of substance.
V = 174 mL ÷ 1000 mL/L = 0.174 L, volume of gas.

<span> T = 15°C = 288.15 K; temperature.
R = 0.08206 L·atm/mol·K, </span>universal gas constant.<span>
Ideal gas law: p·V = n·R·T.
</span>p = n·R·T / V.
p = 0.00825<span> mol · 0.08206 L·atm/mol·K · 288.15 K / 0.174 L.
p = 1.12 atm.</span>
