How much heat is absorbed during production of 112g of no by the combination of nitrogen and oxygen? . n2(g)+o2(g)→2no(g), δh = + 43 kcal/mol

Answer : The heat absorbed during the reaction is 160.4 kcal

Explanation :

First we have to calculate the number of moles of NO.

Molar mass of NO = 30 g/mole

Now we have to calculate the heat absorbed during the reaction.

or,

where,

= enthalpy change = +43 kcal/mol

q = heat absorb = ?

n = number of moles of NO = 3.73 mol

Now put all the given values in the above formula, we get:

Therefore, the heat absorbed during the reaction is 160.4 kcal

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

it is a solid
