a = 2 (NH4OH) b = 1 (H2O2) c = 1 (N2H4) d = 4 (H2O) Step 4: Substitute Coefficients and Verify Result Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. ...
This was confirmed through the study of COP width changes in NH4OH : H2O2 : H2O (SC-1) solution. The COP width depends on the rates of change in width and the shape of its void. The rates of change of width of the COP which originated from the lower portion of the void was found...
