Explain how adding crushed limestone reduces the acidity of the soil. Include a
general equation for the reaction.
Answers
Answer:
If a soil test indicates low magnesium, dolomitic limestone can be used to correct both the nutrient deficiency and pH. The value of limestone is in its ability to neutralize soil acidity. Limestone's properties differ considerably, and these differences influence the limestone's ability to neutralize soil acidity.

What happens to wavelength as wave frequency increases?
Answers
Answer:
As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

ExpErnest Rutherford’s experiments involving the interaction of radiation with a magnetic or electric field (Figure 2) helped him determine that one type of radiation consisted of positively charged and relatively massive α particles; a second type was made up of negatively charged and much less massive β particles; and a third was uncharged electromagnetic waves, γ rays. We now know that α particles are high-energy helium nuclei, β particles are high-energy electrons, and γ radiation compose high-energy electromagnetic radiation. We classify different types of radioactive decay by the radiation produced.
Alpha (α) decay is the emission of an α particle from the nucleus. For example, polonium-210 undergoes α decay:

A liquid changes color as it cools and becomes solid. How can you confirm
the type of change that took place?
A. Determining that the mass of the solid and liquid are different
would confirm that a chemical change took place.
B. Identifying the solid and liquid as the same substance would
confirm that a physical change took place.
O c. The color change and the formation of a solid confirm that a
chemical change took place.
D. The formation of a solid from a liquid confirms that a physical
change took place.
Answers
Answer: Hello, There! your answer is Below.
D. The formation of a solid from a liquid confirms that a physical
change took place.
Explanation:
The change from the liquid state to the solid state is called freezing. As the liquid cools, it loses thermal energy. As a result, its particles slow down and come closer together. Attractive forces begin to trap particles, and the crystals of a solid begin to form.
Hope this helps you!!!
Have a great day!!!
When a liquid undergoes solidification and change of phase it is called freezing. The physical change can be confirmed by changes in the state of matter from liquid to solid. Thus, option D is correct.
What are physical changes?Physical changes are the modification in the matter or object that can be reversed back to its original state. They do not produce substances that are irreversible.
The change of the phase of the matter from liquid to solid when water substance undergoes freezing is a physical change as no new compound is created and the solidified substance can get converted back to liquid.
Therefore, option D. solid from liquid shows a physical change.

To calculate the atoms of an element in a given molecule, we need to multiply stoichiometry by the number that is written on the foot of that element. Therefore, the correct option is option D.
What is Balanced equation?Balanced equation is the one in which the total number of atoms of a species on reactant side is equal to the total number of atoms on product side. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, displacement reaction.
The other characteristic of balanced reaction is that physical state should be written with each compound or molecule on reactant and product side. Physical state should be written in brackets. s means solid, l means liquid, g means gas.
The skeletal equation is
Li + N[tex]_2[/tex] [tex]\rightarrow[/tex] Li[tex]_3[/tex]N
The number of atoms of nitrogen on reactant side is 2 while on product side it is 1 so to balance
Li + N[tex]_2[/tex] [tex]\rightarrow[/tex] 2Li[tex]_3[/tex]N
The lithium atom on reactant side is 1 while on product side it is 6, so to balance
6Li + N[tex]_2[/tex] [tex]\rightarrow[/tex] 2Li[tex]_3[/tex]N
The coefficient of the Lithium is 6.
Therefore, the correct option is option D.

[tex]P_{2}[/tex] = ?, [tex]T_{2} = 5^{o}C[/tex]
Formula used is as follows.
[tex]\frac{P_{1}}{T_{1}} = \frac{P_{2}}{T_{2}}\\\frac{12 psi}{20^{o}C} = \frac{P_{2}}{5^{o}C}\\P_{2} = \frac{12 psi \times 5^{o}C}{20^{o}C}\\= 3 psi[/tex]

Which of the following is the most common source of pollution?

Answers
Answer:
Coal puts out more Co2 emissions than Oil or Gas and Nuclear energy plants don't put out any pollution.
Explanation:
Even though Coal is your answer it is actually a very clean form of generating energy. Not only is it very clean but it is the most effecient means. Solar and Wind power can't even come close to the production and turnover that Coal, Gas, and Oil can. Wind Turbines are so innefficent that they somtimes don't even pay off what it took to build them in thier lifetime of service. The production of Wind Turbines puts out more pollution than any of the Coal or Natural Gas Plants. Solar power is not very efficent either but it is on it's way. It is also very expensive.

The kind of nuclear reaction that occurs in the following reactions are:
i. nuclear fission
ii. nuclear fusion.
What is a nuclear reaction?Nuclear reactions are that reactions in which a nucleus or nuclei collides with subatomic particles to form another, different nucleus. There are two types of collisions. Nuclear fission and nuclear fusion.
Nuclear fission is a process when large nuclei split and create small, numerous nuclei. It happens due to the instability of an atom. It split into two daughter nuclei.
Nuclear fusion is a process in which two or more small nuclei combine to create a large, heavy nucleus. The process releases a large amount of energy or can be absorbed.
Thus, the processes are i. nuclear fission
ii. nuclear fusion.
