The synthesis of nitrogen trihydride from nitrogen gas and hydrogen gas is shown by which balanced chemical equation? a) n2(g) + h2(g) → nh3(g) b) n2(g) + 3h2(g) → 2nh3(g) c) 2nh3(g) + 3h2(g) → n2(g) d) 2nh3(g) → n2(g) + 3h2(g)

Hello!

The synthesis of nitrogen trihydride from nitrogen gas and hydrogen gas is shown by the following balanced chemical equation:

B) N₂(g) + 3H₂(g) → 2NH₃(g)

Why?

The question is saying that the reactants are nitrogen gas (N₂) and hydrogen gas (H₂). This rules out options C and D, because they do not have those reactants.

The remaining options (A and B) show the formation of Nitrogen Trihydride (NH₃, also called Ammonia), from Nitrogen gas and Hydrogen gas, but option A is not balanced (the number of each atom on both sides of the equation is not the same).

So, the correct option is B, it shows the balanced reaction accurately. This reaction is also known as the "Haber-Bosch Process", invented by Fritz Haber and Carl Bosch in the early 20th century.

Have a nice day!

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
