What effect does the spinning of the earth's core have?
A.it creates gravity
B. it creates matter
C. it creates mass
D. it creates the earths magnetic field.

Answers

Answer:

c

Explanation:

its c

Earth contains a spinning electric filed. The spinning of earth core creates its magnetic field. Thus, option D is correct.

What is a spinning body?

A body which rotates in its own axis is called a spinning body. Earth rotates about its along with revolving around sun.  The outer core of earth generates electric current. This is called telluric current.

Flow of this current creates an electric current which is parallels to the surface of earth. The direction of magnetic field lines will be perpendicular to the direction of current. But it comes stronger when parallel to current.

A rotating electric current results in the generation of a magnetic field. Thus spinning of  earth core generates a magnetic field and therefore, option D is correct.

Weathering

Answers

Answer:

Melting

Explanation:

Could not have been erosion because erosion happens on the surface.

Could not have been weathering because weathering happens on the surface.

So we only have Cementing and Melting left....

The answer is melting, I got 100% on my test.

Answer:

D

Explanation:

In the rock cycle, surface events takes place at the surface of earth. Thus,

weathering and erosion are surface events, while the subsurface events he take place in the deeper section of the earth . Examples of sub surface events are plate tectonics and mountain building or anything that takes place in the inner core of earth.

Answer:

I searched the answer up on Brainly so its not my credit.

Explanation:

The answers D.

"If you have learned that metal + nonmetal ⟶ ionic bond, the answer is D, because N and C are the only pair of nonmetals.

However, if you have learned that a bond is ionic if the electronegativity difference (ΔEN) between the two atoms is greater than 0.7, the answer is A, B, and D.

The Li-Cl bond is definitely ionic.

For Na and C, ΔEN =1.62, so the Na-C bond is a highly polar covalent bond.

For Mg and C, ΔEN = 1.24, so the Mg-C bond is a polar covalent."

Would you expect manganese(II) oxide, MnO, to react more readily with HF(aq) or NaOH(aq)?

Answers

Answer:

NaOH(aq)

Explanation:

NaOH(aq) is known to precipitate Mn^2+ ions according to the following reaction; Mn^2+(aq)+2OH^−(aq)↽−−⇀Mn(OH)2(s)

Hence, manganese(II) oxide reacts more readily with NaOH(aq) under ordinary conditions precipitating the metal hydroxide solid. This is one of the characteristic reactions of Mn^2+.

Which statement best describes John Dalton's use of creativity in his work? He reinterpreted and retested Joseph Proust's results. He used a philosophy to conduct his experiment. He recorded his results as four parts of the atomic theory. He rejected Democritus's idea that matter was composed of atoms.

Answers

Answer: The correct statement is that,

'He reinterpreted and retested Joseph Proust's results'

Explanation:

John Dalton was an English chemist who contributed greatly to the field of Chemistry. He published his theory about atom in 1808.

Dalton was the first person to recognize a workable distinction between the fundamental particle of an element (atom) and that of a compound (molecule). The atomic theory generally summaries the laws of chemical composition which includes:

--> law of constant composition and

---> law of multiple proportions.

John Dalton was being creative in his work by reinterpretation and retesting of Joseph Proust's results. Joseph Proust was a French chemist that first discovered the law of constant composition in 1794. This means that many has started working on the atoms before John Dalton discovery.

From the previous works of Proust, he had studied tin oxides and found that their masses were either 88.1% tin and 11.9% oxygen or 78.7% tin and 21.3% oxygen (these were tin(II) oxide and tin dioxide respectively). Dalton retested and noted from these percentages that 100g of tin will combine either with 13.5g or 27g of oxygen; 13.5 and 27 form a ratio of

Dalton reinterpreted it by finding an atomic theory of matter that could elegantly explain this common pattern in chemistry – in the case of Proust’s tin oxides, one tin atom will combine with either one or two oxygen atoms. I hope this helps, thanks.

A.) He reinterpreted and retested Joseph Proust's results

When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.

2SO2(g)
+
O2(g) --> 2SO3(g)

Answers

Answer:

Combination reaction

Explanation:

In Chemistry, elements and compounds are involved in a process called chemical reactions, which are of different types namely: combination, decomposition, double replacement, combustion etc. A combination reaction is that reaction in which two or more substances called the REACTANTS combine together to form a single new substance called the PRODUCT.

In this case, a reaction is depicted as follows:

2SO2(g) + O2(g) --> 2SO3(g)

In this reaction, compound SO2 combines chemically with element O2 to form a single new compound SO3. Hence, this is a type of COMBINATION REACTION.
