Question

Calculate the heat of reaction H for the following reaction Decide whether these proposed Lewis structures are reasonable. H2(g) + Cl2(g)2HCl(g) proposed Lewis structure Is the proposed Lewis structure reasonable? You can find a table of bond energies by using the Data button on the ALEKS toolbar. Yes No, it has the wrong number of valence electrons The correct number is: No, it has the right number of valence electrons but doesn't satisfy the Round your answer to the nearest kJ/mol. octet rule The symbols of the problem atoms are:* Yes No, it has the wrong number of valence electrons. The correct number is No, it has the right number of valence electrons but doesn't satisfy the kJ x 10 mol Draw the Lewis structure for the polyatomic sulfite (SOaion. Be sure to include all resonance structures that satisfy the octet rule the Lewis structure for the polyatomic sulite (so )anion. Be sure to include al octet rule The symbols of the problem atoms are:* Yes No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule The symbols of the problem atoms are:* *If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many times as necessary. For example, if two oxygen atoms don't satisfy the octet rule, enter "O,O".

Explanation / Answer

H-H + Cl-Cl --> 2 ( H-Cl )

Hrxn = Hproducts bonds - Hreactants bonds

H-Cl = 431 kJ/mol

H-H = 436 kJ/mol

Cl-Cl = 242 kJ/mol

so..

Hrxn = Hproducts bonds - Hreactants bonds

HRxn = 2*431 - (436 + 242 ) = 184 kJ
