However, a few participants also showed the need for additional time to better practice SLI. An exemplary quote obtained from the reflection of Hiwot (FG3) can serve as an example: “We need to save our regular classes and I suggest the [SLI] training should be held in extended time to...
The history of chemistry begins in Ancient Greece with the invention of the word "atom," the classification of the four elements (fire, air, water, earth), and the pursuit of alchemy: the attempt to transform cheaper metals into pure gold. Robert Boyle's 17th-century book called The Skepti...

For example, acids and bases are mostly separate from equations and stoichiometry. If none of this is making sense, don’t panic. StudyGate is here to meet your chem homework help needs. Our experts have majored in chemistry and/or are working in the field now. And they want to share ...
Unfortunately, all these innovations are currently limited to text and images, and lack interfaces for adding scientific material such as equations, chemistry, molecular visualization or computer code. There is a pressing need for a standard system of scientific tools in this area, including plug-...
(1952)made the role of geometry explicit by capturing it in mathematical equations and showed that ordered patterns do not need a patterned precursor. He argued that a system of chemical substances, which he called morphogens, reacting together and diffusing through a tissue, could explain the ...
The etymology of the word chemistry has been much disputed and obscure. However most of it is evolved from the medieval practice of alchemy. The foundations of this fascinating subject can be found along the timeline of development of science and technology from ancient times to modern era. ...
