Part B 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

Question 1:

The natural gas starts by piping natural gas underground to power plants, then the power plants burn the natural gas to boil water that becomes steam. The steam spins the blades of a turbine that is connected to a generator, then the generator spins the magnets which generate the electricity.

Part B:

Natural gas: The original form of natural gas is a fossil energy source. Natural gas plants use a gas turbine; natural gas is added, along with a stream of air, which combusts and expands through this turbine causing a generator to spin a magnet, making electricity.

Coal: The original form of coal is peat. Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into the water, and returned to the boiler to restart the process.

Nuclear fuel: Sorry couldn't do this one, it's 4 am and my brain just isn't working w me too well.

Hydropower: The original form of hydropower is water. The hydropower plants water flows through a pipe, or penstock, then pushes against and turns blades in a turbine to spin a generator to produce electricity

Wind: Sorry couldn't do this one either.

I'm sorry I didn't do two of them but I really hope this helps.

part 1: the half-life of the element is 22 years.

part 2: it will take 132.02 year for the sample to decay from 308.0 g to 4.8125 g.

explanation:

part 1: there are two ways to determine the half life time.

first way: the half life time can be determined directly from its definition as it is the time required for the sample to decay to its half concentration.

from the data the initial concentration was 45.0 g and decayed to its half value (22.5 g) in 22.0 years.

second way: the radio active decay is considered first order reaction so we can use the laws of first order reactions.

k = (1/t) ln (a/a-x), where k is the rate constant of the reaction,

t is the time of the reaction

a is the initial concentration of the reactant

a-x is the remaining concentration at time (t)

a = 45.0 g the initial concentration at t = 0 year.

at t = 22 year, a-x = 22.5 g

then k = (1/22 year) ln (45.0 g/ 22.5 g) = 0.0315 year-1.

the half-life time (t1/2) = ln 2/ k = 0.693/ k =0.693/ 0.0315 = 22 years.

part 2:

using the same law k = (1/t) ln (a/a-x),

using the given data; a = 308.0 g and a-x = 4.8125 g and the calculated k from the part 1 (k = 0.0315 year-1)

t = (1/k) ln (a/a-x) = (1/0.0315) ln (308.0/ 4.8125) = 132.02 years
