Nettet13. mai 2014 · This reaction is the synthesis of Ammonia using Nitrogen and Hydrogen gas. N + H -> NH_3 We must remember that Nitrogen and Hydrogen are both diatomic molecules in their standard gas form. This adjusts the equation to N_2 + H_2 -> NH_3 Now we need to adjust coefficients in order to balance the atoms on each side of the … NettetNaH is a saline (salt-like) hydride, composed of Na + and H − ions, in contrast to molecular hydrides such as borane, methane, ammonia, and water. It is an ionic material that is …
