The first IE `(Kj mol^(-1))`of group 13 elements are
`B/801 Al/577 Ga/579 In/558 Tl/589`
How would you explain the deviation from general trend ?

The first IE and second IE (Kj mol^(-1)) and dalta_egH(kJ mol^(-1)) of a few elements are given below: Which of the above is likely to be the metal that can from perdominantly stable covalent halide (MX) ?

The first IE and second IE (Kj mol^(-1)) and dalta_egH(kJ mol^(-1)) of a few elements are given below: Which of the above is likely to be the metal that can from stable binary halide (MX_2)

The first ionization enthalpy (IE) of the third period elements 'Na, M g', and 'S i' are respectively 496,737 and '786(kJ mol^(-1)) .' Predict whether the first 'IE' value for 'Al' will be more close to 575 or '760 kJ' mol '^(-1)'. Justify your answer.

Construct a reaction between carboxy haemoglobin with oxygen from the following equations. Haemoglobin +O_2 (aq) rarr Oxyhaemoglobin, Delta H_(l)=-23.1 kJ / mol rarr(1) Haemoglobin +CO (aq) rarr Carboxyhaemoglobin, Delta H_(2)=,-32.4 kJ / mol rarr(2) a. Using the value of Delta from your equation, account for the extreme toxicity of carbon monoxide. b. What are the sources of carbon monoxide in the atmosphere. How can you rectify the adverse éffects of C O in atmosphere?
