According to the big bang theory, which statements are accurate about how the universe came to be? Check all that apply.
asambeis [7]

The term Big Bang defines that the Universe has expanded from the ancient hot and thick primary situation at some fixed time in the past.

Big Bang theory refers to the origin of the Universe. In the beginning, universe is very heavy and small hot ball of matter. It was a point no bigger than the head of a pin when all the things squished with each other and universe is expanded with huge explosion of energy. Due to expansion, it is cooled and results in the formation of Stars and galaxies. After sometime, atoms formed like helium and hydrogen.

Thus, statement (1), (3) and (4) is correct whereas statement (2) and (5) is incorrect.

Ammonia is a principal nitrogen fertilizer. It is prepared by the reaction between hydrogen and nitrogen. 3H2(g) + N2(g) → 2NH3(
sergey [27]

Answer:

Explanation:

The equation of the reaction is given as:

             3H₂ + N₂ → 2NH₃

Given parameters:

Number of moles of NH₃ = 8moles

Number of moles of H₂ = ?

Number of moles of N₂ = ?

Solution

From the balanced reaction equation, we can establish some mole ratios that would help solve the problem:

 To find the number of moles of H₂;

      The equation shows that:

              2 moles of NH₃ were produced using 3 moles of H₂

therefore: 8 moles of NH₃ will be produced by  \frac{8 x 3}{2} = 12moles

So, 12 moles of hydrogen gas will react to give 8 moles of ammonia.

   To find the number of moles of N₂

 The equation shows that:

       2 moles of NH₃ were produced from 1 mole of N₂

      8 moles of NH₃ would be produced from  \frac{8 x 1}{2} = 4moles of Nitrogen gas

Therefore, 4moles of nitrogen gas would be produced
