Thermal Energy, Electrical Energy, Light, Sound, Nuclear Energy, and Chemical Energy
Answer:
45.7kj
Explanation:
To calculates the heats of reaction from heats of formation:
∆Hr=£∆Hp -£∆Hr
= £∆Hch3ChOH - £∆HCh2h2+h20
=(-235.1kj)-(+52.47kj/kg + (-241.8kj/kg)
∆H = 45.71kj/kg
<span>Distillation, filtration, evaporation are some of the techniques by which mixtures can be resolved into their components.Distillation is the process of separating the component or substances from a liquid mixture by selective evaporation and condensation.Filtration is any of various mechanical, physical or biological operations that separate solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass.Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance.</span>
