First you write the equation, then balance it.
Ba(OH)2(aq) + 2HNO3(aq) ==> Ba(NO3)2)aq) + 2H2O(l)
Next you use the coefficients in the balanced equation (that's why you write and balance the equation FIRST) to convert mols HNO3 to mols Ba(OH)2.
2.5 mol HNO3 x [1 mol Ba(OH)2/2 mol HNO3] = 2.5 x (1/2) = ? mols Ba(OH)2
I seriously don't understand this...i cant even begin to think of what to do please help...
How many moles of Ba(OH)2 does it take to neutralize 2.5 moles of HNO3?
