The electricity we use is generated from many different sources of energy. The five sources used most in the United States are natural gas, coal, nuclear fuel, hydropower, and wind. For each of these sources, describe the original form of the energy and the way in which it’s converted to electrical energy. Do Internet research, as needed, to describe each energy source. Question 1
Describe the energy in natural gas and the way in which it’s converted to electrical energy. Write 50 to 100 words.

Answer explain why it is not possible to deduce a complete order of reactivity.

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
