N2 + 3 H2 --> 2 NH3
Anna71 [15]

Answer:

4 moles of NH3 will be produced

Explanation:

The reaction expression is given as:

            N₂  +  3H₂  →  2NH₃

We have to check that the equation of the reaction is balanced.

 Then;

      if 2 mole of N₂ reacts;

 1 mole of N₂ will react with 3 mole of H₂ to produce 2 mole of NH₃

2 mole of N₂ will react with (2x3)mole of H₂ to produce (2x2)mole of NH₃

                                                    6mole of H₂ to produce      4 mole of NH₃

Imagine an alternate universe where the value of the Planck constant is 6.6207 x 10^-36 J*s.
Salsk061 [2.6K]

Answer:

See explanation

Explanation:

According to Louis de Broglie, matter has an associated wavelength. He was the first scientist to establish the idea of wave-particle duality or wave- particle paradox.

The display of wavelike properties by objects in the universe is dependent on the magnitude of the of the mass of the body. Small objects have a large associated wavelength and can be described completely by quantum mechanics.

A buckyball with a mass of 1.2 x 10-21 g, 0.7 nm wide, moving at 38. m/s has a very small mass and significant associated wavelength hence the system can be completely described by quantum mechanics.
