Please Help - Chemistry Problem! one of the steps in the commercial process for converting ammonia to nitric acid involves tha catalytic oxidation of NH3 to NO: 4NH3(g) + 502(g) -> 4NO(g) + 6H2O(g)

How many grams of NO are formed by the complete reaction of 2.50 g of NH3?

The correct answer is "atomic weight".

2licl + 3o2 i yook the test and it was correct.

Answer//the law of conservation of mass.;

Electron equations of the given changes are as follow,a)                              cu      →      cu⁺²  + 2e⁻b)                              mg⁺²  +  2 e⁻      →      mgc)                              cl⁻    →      cl  +  1e⁻d)                              s  +  2 e⁻    →      s²⁻e)                                o²⁻      →      o  +  2 e⁻f)                              p  +  3 e⁻    →      p³⁻g)                              fe²⁺    →      fe³⁺  + 1 e⁻h)                              s²⁻    →      s⁴⁺  +  6 e⁻
