Amount in moles equivalent The mole is a unit of measurement used in chemistry to express amounts of a chemical substance solution and mole is widely used in chemistry, instead...
4NH3 + 7O2 = 4NO2 + 6H2OAccording to the equation NH3 reacts completely, O2 is in the excess.7 mol of NO2 will be produced.According to the equation 7mol*7/4 = 12....
H2SO4 is strong electrolyte, completely dissolves into ions:H2SO4 <=> 2H+ + SO4-Hence: [H+]=4mol/lpH=-lg [H+]=-lg4=-0,6 (negative meaning pH)HCl is strong electrolyte, completely dissolves into ions:HCl <=> H++Cl-Hence: [H+]=0,326mol/lpH=-lg [H+]=-lg0,326=0,49c(HCl)=0,326mol/lHence in 65ml...
Mg(OH)2+2HCl=MgCl2+2H2O1.Trace by finding the amount of Mg(OH)2. To do this, we multiply the molarity by the volume (liters): 0.03462litres *0.3 mol/litres= 0.010386 mol Mg(OH)22.based on the reaction we find the amount...
