Mean = Average (14 + 6 + 4 + 12)/4 = ? (36)/4 = 9 Mean of the data is 9.
Mean(52349, 4) = (52349+ + 4)/2 = 26176.5
There is not much point in calculating the mean or mode of a single number. The mean of 5 is 5. The mode of 4 is 4.
The mean is the average = (6+9+101+4)/4 = 30
4^4 = 4*4*4*4 = 256
Cu2+ + 4NH3 ----> [Cu(NH3)4]2-
3N2H4 --> 4NH3 + N2 is the correctly balanced equation.
calcium ammonia chloride
A concentrated solution of ammonia is added to a solution of copper II nitrate 4NH3(c) + Cu2+ --> [Cu(NH3)4]2+
4NH3 + 5O2 -----> 4NO + 6HOH
Yes - there are equal values of nitrogen (4) and hydrogen (12) on both sides of this equation, and all molecular formulas are in empirical form.
this is the balanced equation 4NH3 + 5O2 = 4NO + 6H2O
4NH3 + 3O2 -----> 2N2 + 6H2O 4 moles of ammonia react with 3 of oxygen. So 10 moles of ammonia requires 7.5 moles of oxygen.
nitrogen monoxide and Water The balanced equation is as follow: 4NH3 + 5O2-->4NO + 6H2O
3IBr + 4NH3 --> NI3 + 3NH4Br
2[Ag(NH3)2]+ + CH3CHO + 3OH- --> 2Ag + 2H2O + 4NH3 + CH3COO-
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.
