Explain three ways in which you have used any branch of chemistry in your everyday life. explain how the five branches of chemistry can and very often do overlap.

Here you have 3 examples of the using of chemistry in our everyday life:

√ When someone uses baking soda and lemon to clean the bathroom. This is an application of organic chemistry since there's an acid-base reaction between the organic acid in the lemon and the baking soda.

√ Creating home-made yogurt is also an example of biochemistry since this is produced due to a fermentation process.

√ All the food we consume daily is produced after a combination of chemical processes: A lot of inorganic, organic and biochemical reactions are performed in the food industries to produce our food.

The last example is also a good way to explain how the five branches of chemistry (Organic, Inorganic, Analytical, Physical and Biochemistry) are related: First we have all of the reactions involved in the production, we also have the analytical procedures to determine, for example, that the concentration of carbon compounds in the water are under the limit level. In the bioreactors (used for beer production, for example) we have a good application of Physical chemistry since all the procedures need to have determined thermodynamical conditions.

Hope this helps!

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
