Today Chemistry plays an important role in our everyday lives. When you come to think about it, it is in everything that we do. Define chemistry in your own words and list at least FIVE(5) examples of how you applied chemistry today.
Limestone, CaCo3, when subjected to a temperature of 900 degrees Celsius in a kiln, decomposes to calcium oxide and carbon dioxide. How much heat is evolved or absorbed when one gram of limestone decomposes?
What is the [HS-] of the solution. If 0.01 M of each of the following ions is in the solution,which will form a precipitate
In glycogen degradation, what enzyme is responsible for releasing a glucose molecule attached to the main glucose chain at a branch point
