4NH3(g) + 5O2(g) 4NO(g) + 6H2O(g)
2[Ag(NH3)2]+ + CH3CHO + 3OH- --> 2Ag + 2H2O + 4NH3 + CH3COO-
The most practical application of the Tollen's reaction is to detect an aldehydic group in a compound. The reaction is as follows: RCHO + 3OH- + 2[Ag(NH3)2]+ --> RCOO- + 2H2O + 2Ag + 4NH3.
3N2H4 --> 4NH3 + N2 is the correctly balanced equation.
4nh3 + 5o2 --> 4no + 6h2o
calcium ammonia chloride
4NH3 + 6NO -> 5N2 + 6H2O 145 g N2 x (1 mol/28.0 g) x (6 mol NO/5 mol N2) x (30.0 g NO/1 mol NO) = 186.4285714 g NO rounds to 186 g NO due to significant figures
4NH3 + 5O2 -----> 4NO + 6HOH
A molar ratio is the ratio of any two coefficients in a stoichiometric equation. So in this case, there are six possible combinations. 4:6, 4:5, 4:6, 6:5, 6:6, 5:6.
s is positive and g i s negative at all temperatures
Cu2+ + 4NH3 ----> [Cu(NH3)4]2-
it is know as the silver mirror test, the overall half equation reaction is => CH2O + 2OH- ==> CH2O2 + H2O +2e- [Ag(NH3)2]+ + e- ==> Ag + 2NH3 CH2O + 2OH- + 2[Ag(NH3)2]+ ==> CH2O2 H2O + 2Ag +4NH3
