WebAll the matter around us are made of tiny particles called atoms and molecules. While atoms of an element represent only one kind of particle, molecules are made of either the same or different kinds of one or more particles. This difference defines the two classes of compounds, namely heteroatomic and homoatomic molecules. WebMolecular motion is defined as the movement of constituent particles or molecules in a certain direction. The molecular motions are affected by heat and temperature. This is because temperature is the measurement of the average kinetic energy of the molecules and represents the motion of molecules. Similarly, heat transfers energy among ... high schools shelby nc https://manganaro.net

WebA non-polar molecule has a structure of its atoms lined up in a way that the orbital electrons in the outer region cancel out the electronegativity. In general, pyramid-shaped and V-shaped molecules are said to be polar. Whereas the Linear molecules are said to be non-polar in nature. Water is said to be a polar molecule due to the difference ... WebSolution. The interparticle force of attraction can be defined as the force of attraction exerted between particles (atoms, molecules). For eg, In solid particles are very close so their interparticle space is very little while gas particles are very far from each other so their interparticle space is large. Suggest Corrections.

WebFirst, the chlorine atoms are balanced. The equation becomes Cl 2 + KBr → 2 KCl + Br 2; Now, the bromine atoms must be balanced, there is one bromine atom on the reactant side and 2 on the product side. Therefore, there must be 2 Br molecules on the reactant side. The chemical equation is transformed into Cl 2 + 2 KBr → 2 KCl + Br 2
