Answer:
7923.6 g of (NH₄)₂SO₄ can be produced by this reaction
Explanation:
The reaction is:
2NH₃ (aq) + H₂SO₄(aq) → (NH₄)₂SO₄(aq)
In this reaction ratio is 1:1.
As the ammonia is in excess, the limiting reagent is the sulfuric acid.
So 1 mol of sulfuric can produce 1 mol of sulfate
Then, 60 moles of sulfuric must produce 60 moles of sulfate.
We convert the moles to mass:
60 mol . 132.06 g / 1mol = 7923.6 g
Two atoms far apart being brought closer to each other, their potential energy decreases until the nuclei repel each other (the repulsion). The nucleus of one atom is attracted to the electrons of the other atom. As the distance gets less, the potential energy gets less.
Answer:
las plantas
Explanation:
Las plantas son los seres vivos capaces de transformar energía luminosa utilizando agua y dióxido de carbono (CO₂) en energía química en forma de moléculas llamadas carbohidratos. El proceso a través del cual realizan esto se denomina fotosíntesis, y para ello requieren un pigmento de color verde denominado clorofila, el cual es necesario para captar la energía luminosa proveniente del Sol.
States that mass is an isolated system is neither created nor destroyed by chemical reactions or physical transformations
Explanation:
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.
