1.	While performing a thermodynamics experiment, a student made the following observations, HCl + NaOH → NaCl + H2O ΔH = –57.3 kJ mol–1 CH3COOH + NaOH → CH3COONa + H2O ΔH = –55.3 kJ mol–1. The enthalpy of ionization of CH3COOH as calculated by the student is ______ kJ mol–1. (nearest integer)
Answer» ΔH_ionisation of CH₃COOH = \|-57.3 - (-55.3)\| = 2 KJ/mol

How do biofertilisers enrich the fertility of the soil?
Read carefully the passage and select the correct answer out of given four options:Biofertilizers are organisms that enrich nutrient quality of the soil. The important sources of biofertilizers are bacteria, fungi and cyanobacteria. The symbiotic association of Rhizobium with the root nodules of leguminous plants is the common example.
