Anitrogen atom can undergo sp2 hybridization when it becomes part of a carbon–nitrogen double bond, as in h2c=nh. (a) using a sketch, show the electron configuration of sp2 hybridized nitrogen just before the overlapping occurs to make this double bond. (b) using sketches (and the analogy to the double bond in c2h4), describe the two bonds of the carbon– nitrogen double bond. (c) describe the geometry of h2c"nh (using a sketch that shows all expected bond angles).

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
