Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity,flammability, and the ability to rust. Why flammability is chemical property?
Along with the development of society, more and more problems are brought to our attention, one of the most serious issue is the gray population. Nevertheless, the significance of elderly people in society cannot be overstated. As...
Companies sometimes add chlorine bleach to industrial wastewater to reduce odor, and chlorine is used by the glass, chemical, pharmaceutical, textile, agriculture, paint and paper industries. With its many uses, bleach its a very familiar product to most people. But when did we start using this...
The lower the molecular weight of the thiol, the more intense the smell. It is a thiol, known as t-butyl mercaptan, that is used to give natural gas an odor. Coenzyme A is produced in the body, but can also be taken as a nutritional supplement. In theory, the intake of this ...
Firstly, elderly people possess a wealth of knowledge and life experience that are invaluable to the younger generations. Their wisdom, acquired through years of living and learning, provides a unique perspective on life and offers guidance to the younger members of society. By recognizing and appre...
Lead-acid batteries generate electricity through a double sulfate chemical reaction. Lead and lead dioxide on the negative and positive electrodes of a battery react with sulphuric acid in the electrolyte to form lead sulfate. How long do lead-acid deep cycle batteries last? Both car batteries, ...
