Homework Statement Consider the following reaction. 2 HCl(aq) + Ba(OH)2(aq) BaCl2(aq) + 2 H2O(l) ΔH = -118 kJ Calculate the heat when 100.8 mL of 0.500 M HCl is mixed with 300.0 mL of 0.450 M Ba(OH)2. Assuming that the temperature of both solutions was initially 25.0°C and...
Is it correct to find it this way? Number of moles of HCl = 1 mol Number of moles of H2O = 1000/18 = 55.6 mol So, total number of moles = 55.6 + 1 = 56.6 molesIf i change the question of 3 mol dm-3 of HNO3, Then the total... ...
