1.The chemical stability of magadrate was investigated and the result showed that the chemical property of magaldrate was not changed under the high temperature and high relative humidity.
4.Basically, the heat causes the lipids in the oil to break down and produce some volatile compounds, which are chemicals that can easily become gases.
6.Miller said, " Heat is one of the greatest risks that we have in this work, even though we deal with high radiation, hazardous chemicals and heavy metals."
7.We still don't know how the ancient Egyptians originally figured this recipe out, but the chemical reaction would have required careful control of this super hot temperature and the flow of oxygen into a furnace.
8.The heat and the chemicals used to separate metal from dirt or hazardous can make workers sick but for many who pan the streets for gold, a steady source of income is often more important than their health.
