substance is additionally easily determined. Accordingly‚ the heat unconstrained can be calculated for as soon as every one of the variables on the right side of the equation has been discovered. Hess’ Law‚ which says that the heat of configuration (enthalpy change‚ ΔH) of a reaction can be compute by taking away the ΔH of the products from the ΔH of the reactants‚ is illustrated through this lab experiment. This lab contains two purposes. In the first part‚ the temperature change is calculated when

why water has low vapour pressur and high surface tension Ok‚ well the answer to your first question is hydrogen bonds. Water has high surface tension and low vaporization temp because the hydrogen bonds in water make strong dipoles that are difficult to separate (yielding high surface tension) and greater energy to overcome when vaporized. study help site http://ocw.mit.edu/courses/physics/8-01-physics-i-classical-mechanics-fall-1999/syllabus/ Explain gas laws through KMT acc to k.m.t gasses

Molecular modelling is the general term used to describe the use of computers to construct molecules and perform a variety of calculations on these molecules in order to predict their chemical characteristics and behaviour. The term molecular modelling is often used synonymously with the term computational chemistry. Computational chemistry is a broader term‚ referring to any use of computers to study chemical systems. Some chemists use the term computational quantum chemistry to refer to the use
