On the creation of chemical industry
The way of chemical industry is mysterious and infinite, with $H_f $as the core, to explore the wonders of material change. $H_f $, the enthalpy of formation is also important in chemical industry.

In the chemical industry, all kinds of reactions are intertwined, materials are converted, and energy is changed. $H_f $is the basis of the thermal effect of the balance reaction. If it is reasonable, the reaction will be backwards and backwards, and the energy will change. If the combination of various substances, $H_f $can be broken, and its thermal change can be predicted. If the reaction $H_f $is negative, it is a sign of energy release, and its potential is like a flow, spontaneous formation; if it is positive, external force is required to supply energy before it can be carried out.

In chemical design, consider $H_f $, which can seek the selection of equipment and the excellence of the process. Make energy adaptation, materials flow smoothly, so as to achieve the purpose of high efficiency and energy saving. And in the study of reaction mechanism, $H_f $is the key, opening the door to the microscopic world, helping our generation to understand the secret of atomic and molecular clutch.

View the development of chemical industry, relying on the principle of $H_f $, creating thousands of products and benefiting all people. From daily products to cutting-edge materials, it all depends on the intensive research of chemical technology. And $H_f $has always been its guide, guiding the road of chemical industry, and rising to the peak of science and practical environment. The wonders of chemical industry, because of $H_f $and more prominent, the future road, will also be based on this, open up a new chapter, for the progress of the world, contribute endless power.
