Nuclear power plants generate heat by a nuclear reaction and lets out less pollution, a power plant generates electricity by burning fossil fuels and lets out more pollution
<u>Answer:</u> The concentration of acetic acid in the vinegar is
<u>Explanation:</u>
To calculate the pH of the solution, we use the equation:
We are given:
pH = 2.95
Putting values in above equation, we get:
The chemical equation for the ionization of acetic acid follows:
The expression of for above equation follows:
We are given:
Putting values in above expression, we get:
So, the concentration of acetic acid =
Hence, the concentration of acetic acid in the vinegar is

Question 1:
It is better to use data from three or more seismic stations to find the epicenter of an earthquake because it gives a precise and accurate location better than using a lesser amount of data.
Finding epicenter of an earthquake works on the basis of triangulation.
- The intersection between three circles gives the epicenter.
- To triangulate, we simply use a radius value to draw a circle of appropriate size.
- This is the distance of the station from the earthquake.
- We know using seismograph that the first wave to arrive a point is the p-waves and the s-waves follows.
- Disparity between the time of arrival and the velocity of the wave can give us the distance the wave must have traveled.
- We take this data and draw circle of appropriate radius indicating the probable regions where the epicenter might be located.
- This is a wide and indefinite volume of space.
- Three circles using data from two more stations will give a perfect intersection.
- More stations will further improve the accuracy and then we are sure of where the epicenter is.

Question 2:
P and S-waves are seismic elastic waves that travels within the earth. They are usually produce when a huge vibration travels within a substance or within the earth.
After the passing of the wave, the body returns back to its original form.
P-waves:
- They are called primary waves.
- They have the fastest velocity and the are the first to be picked up at a seismic station.
- They can propagated through any material.
- These waves are longitudinal waves moving in a series of rarefaction and compression.
S-waves:
- They are secondary or shear-waves.
- They are the second to arrive seismic station.
- They cannot pass through fluids because they do not shear.
- They are transverse waves that travels perpendicular to their source.

Question 3:
If a seismogram from a particular seismic station shows only P-waves, one can conclude that the material is only made up of fluid materials.
- P-waves are primary waves capable of moving in any material medium.
- They are longitudinal waves that propagates parallel to their source.
- The reason why we cannot pick other seismic waves is that, s-waves cannot pass through fluids.
- S-waves are secondary or shear waves.
- Fluids cannot be sheared.
- Only solids can shear.
- Therefore, we can imply that since we see only p-waves the material is made up of only fluids.

Hey there!:
Molar mass FeF3 = 112.84 g/mol
Number of moles = mass of solute / molar mass
Number of moles = 24.0 / 112.84
Number of moles = 0.212 moles of FeF3
Hope that helps!
Answer:
How Radiation Affects Your Body. Radiation can damage the DNA in our cells. High doses of radiation can cause Acute Radiation Syndrome (ARS) or Cutaneous Radiation Injuries (CRI). High doses of radiation could also lead to cancer later in life.
Because radiation kills rapidly dividing cells (which is why we use it to treat fast-growing cancer cells), radiation exposure most increases the risk of cancers of rapidly dividing cells — leading to leukemia, lymphoma, breast cancer, bladder cancer, colon cancer, liver cancer, lung cancer, esophageal cancer, ovarian
