Answer: Mantle
Explanation:
there are 3 layers of the earth- core, mantle and crust. The layer found directly above the earth's core is the mantle.
Answer:
The answer depends on what you are taking about: the outer core or the inner core?
Answer: Mantle
Explanation:
If you find a picture of the Earth's layers, you can see that the inner core is the bottommost layer. However, if you combine the Inner Core and Outer Core, that could be determined as the Earth's core.
I would chose the Mantle because if the two cores are combined, the layer directly above them is the Mantle.

What is the best way to statically charge an object,
Answer:Static electricity can be created by rubbing one object against another object.
Explanation: This is because the rubbing releases negative charges, called electrons, which can build up on one object to produce a static charge

What is the mass of 3.25 moles of sodium hydroxide (NaOH)?
Answer:
1 mole is equal to 1 moles NaOH, or 39.99711 grams.
Explanation:
Hope this helps have a nice day :)
The statement of the mass of sodium hydroxide (NaOH) is "130 g."
What is mass?A substance is something to do with mass that takes up space. The mass of a compound is the total amount of atoms present in grams that make up a molecule. The grams is the unit of mass.
In order to determine the mass in grams, multiply moles of the substance value by its molar mass to convert moles into grams.
Mole to gram conversion factor,
[tex]=\;given \;mole\;.\;\frac{grams}{1\;mol}[/tex]
Mass of NaOH comes out to be,
[tex]=\;3.25\;mol\;.\;\frac{39.997\;g}{1\;mol}[/tex]
= 129.99 g
= 130 g
Hence the correct answer is 130 g.

Will there ever be grams of a limiting reactant remaining after a reaction has stopped? Why or why not?
Assuming the reaction is complete, there should be no limiting reactant remaining after a reaction. This is because the limiting reactant, by definition, is "the reactant that is completely used up in a reaction."

On a coordinate plane, which single transformation could map point A (3,-4) onto point A' (1.5,-2)? *
Answer: A dilation with rule: [tex](x,y)\to(\dfrac12x,\dfrac12y)[/tex]
Explanation:
A dilation is a non-rigid transformation that creates an image that is the same shape as the original but has a different size.
It uses a scale factor k such that
[tex](x,y)\to(kx,ky)[/tex]
(x,y)= coordinates of original figure
(kx,ky) = corresponding coordinate in the image.
To transform: A (3,-4) onto point A' (1.5,-2).
Using scale factor k= [tex]\dfrac12[/tex], we have
[tex]A(3,-4)\to A'(\dfrac12\times3, \dfrac12\times-4)=A'(1.5,-2)[/tex]
Required rule: [tex](x,y)\to(\dfrac12x,\dfrac12y)[/tex]

Which radioisotope requires long-term storage as the method of disposal, to protect living things from radiation exposure over time?
Pu-239
FR-229
Fe-53
P-32
Answer:pu-239
Explanation:
Pu-239 is regarded as the radioisotope requires long-term storage as the method of disposal, to protect living things from radiation exposure over time
Disposal of radioactive nuclear waste is often regarded as a problem.
The waste sources are:
Nuclear power reactors Bomb-related nuclear materialDisposal of bomb-grade plutonium is often difficult.
The longer lived isotopes are:
Plutonium-239 whose t1/2 is 24,110 years, Plutonium-240 whose t1/2 is 6,540 years, Curium-245 whose t1/2 is 8,500 years. etc.The storage of the longer lived elements is through containment for the next several thousand of years.
The control or management of radioactive waste is a hard, multifaceted procedure.

The number of grams of sulfur in 223 grams of sodium sulfate is . . . Grams And explain how, I still dont get it fully
Answer:
50.25 g of sulphur, S.
Explanation:
Mass of Na₂SO₄ = 223 g
Mass of sulphur =?
Next we shall determine the molar mass of Na₂SO₄. This can be obtained as follow:
Molar mass of Na₂SO₄ = (23×2) + 32 + (16×4)
= 46 + 32 +64
= 142 g/mol
Mass of S in 142 g of Na₂SO₄ = 32 g
Finally, we shall determine the mass of S in 223 g of Na₂SO₄. This can be obtained as follow:
142 g of Na₂SO₄ contains 32 g of S.
Therefore, 223 g of Na₂SO₄ will contain = (223 × 32) / 142 = 50.25 g of S.
Thus, 223 g of sodium sulfate, Na₂SO₄ contains 50.25 g of sulphur, S.

Give an example of a decomposer, and explain what would happen if decomposers were absent from a forest ecosystem. Provide evidence to support your claim and explain your reasoning
Answer: Bacteria, some insects, and fungal species are the decomposers of the dead and decaying matter.
Explanation:
The decomposers are the organisms which act and feed on the dead and decaying organic matter so as to obtain energy from it and degrade it to the simple forms that can be utilized by the plants. Bacteria, some insects and fungi that live in the soil and on the decaying matter. The fungi for example decay on the lignin present in the wood so helps in wood decomposition of trees. If the decomposer like fungi are absent the wood mass will not decompose and it will remain as waste and can be used by the plants in the form of nutrients.
