The enthalpy tell us about the heat that may be absorbed or evolved in a reaction. The ethalpy of this reaction is -100 kJ/mol.

<h3>What is enthalpy?</h3>

The term enthalpy deals with the heat that is absorbed or emitted in a reaction. The reaction equation is; HNO3 + KOH ----> KNO3 + H2O

Number of moles of HNO3 = 0.5 M * 50/1000 L = 0.025 moles

Number of moles of KOH= 0.5 M * 50/1000 L = 0.025 moles

Since the reaction is 1:1, then heat evolved = - (2500 J * 10^-3)/0.025 moles

= -100 kJ/mol

A conductor is distinguished from an insulator with the same number of atoms by the number of:_____.
Savatey [412]

A conductor is distinguished from an insulator with the same number of atoms by the number of nearly free electrons.

<h3>What are conductors and insulators?</h3>

Whether an object is made of conductive or nonconductive material affects how it behaves once it has been charged. Electrons can move freely between particles when they are in conductors, which are substances. The charge can be transported across the whole surface of an object constructed of a conducting substance.

A charge is swiftly dispersed across the full surface of the object if it is applied to it at a specific point. The motion of the electrons causes the distribution of charge. A charged object will constantly disperse its charge until the overall repulsive interactions between surplus electrons are minimized because conductors allow electrons to be moved from particle to particle.

Insulators, as opposed to conductors, are substances that prevent electrons from freely moving from one atom or molecule to another.
