calculate the amount of heat envolve when 200cm3 of 0.2m HCL solution

1.	calculate the amount of heat envolve when 200cm3 of 0.2m HCL solution is mixed with 300cm3 of 0.1m NaOH solution
Answer» tion:Answer500 CM 500 cm 3500 cm 3 of 0.1 M HCl corresponds to 0.5×0.1=0.05 moles of hydrogen ions.500 cm 3 of 0.1 M HCl corresponds to 0.5×0.1=0.05 moles of hydrogen ions.200 cm 500 cm 3 of 0.1 M HCl corresponds to 0.5×0.1=0.05 moles of hydrogen ions.200 cm 3500 cm 3 of 0.1 M HCl corresponds to 0.5×0.1=0.05 moles of hydrogen ions.200 cm 3 of 0.2 M NAOH corresponds to 0.2×0.2=0.04 moles of HYDROXIDE ions.500 cm 3 of 0.1 M HCl corresponds to 0.5×0.1=0.05 moles of hydrogen ions.200 cm 3 of 0.2 M NaOH corresponds to 0.2×0.2=0.04 moles of hydroxide ions.sodium hydroxide is completely neutralize by Hcl500 cm 3 of 0.1 M HCl corresponds to 0.5×0.1=0.05 moles of hydrogen ions.200 cm 3 of 0.2 M NaOH corresponds to 0.2×0.2=0.04 moles of hydroxide ions.sodium hydroxide is completely neutralize by HCLTHE enthalpy of neutralisation is 57.3 kJ/mol. For 0.04 moles, the enthalpy of neutralisation is 0.04×57.3=2.292 kJ
