Which of the following is a subsurface event that takes place during the rock cycle?
Group of answer choices
Cementing
Erosion
Melting
Weathering
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.
Hope this helps!!!! :D
Please give brainliest!!!
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.
Would you expect manganese(II) oxide, MnO, to react more readily with HF(aq) or NaOH(aq)?
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+.

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."

When fossil fuels, such as gasoline, are burned, they create smoke. Smoke is best described as a heterogeneous mixture of solid particles from the burning fuel dispersed in a gas – usually air. Smoke can be described more specifically as a suspension. What will most likely happen over time to smoke in the atmosphere? The solid particles will spread out and dissolve. The particles will eventually come together in a cloud and produce rain. Over time, the solid particles will settle on whatever is outside. The particles will remain mixed in the air.
Answer:
Over time, the solid particles will settle on whatever is outside."

How many Nitrogen molecules are present? ___________
How many Oxygen molecules are present? ___________
How many N2O molecules are present? ___________
The molecules of Nitrogen, oxygen, and N₂O are 2, 1, and 2 respectively.
What is the chemical equation?A chemical equation can be defined as the expression of a chemical reaction in terms of the chemical symbols of the substances. A chemical equation has reactants, formed products, and an arrow indicating the direction of the reaction.
The equation in which the number of atoms of each element is equal on either side of the chemical equation of a reaction is called a balanced chemical equation.
According to the law of mass conservation, the total mass of the elements on the reactant side should be equal to the total mass of elements on the product side.
Given, the chemical equation of the reaction of nitrogen ad oxygen gas can be written as:
2N₂ + O₂ → 2N₂O
The number of molecules of Nitrogen gas is 2 and the molecules of oxygen gas are one and the molecules of N₂O are equal to 2.

Methanol, propan-1-ol and ethanol has boiling point of 65 degree celsius, 97 degree celsuis, 87 degree celsuis respectively. A student uses fractional distillation to separate a mixture of these compound. State which liquid will be collected in the second fraction and explain why
Answer:
ethanol
Explanation:
Methanol has a boiling point of 65°C, propan-1-ol has a boiling point of 97°C and ethanol has a boiling point of 87°C
Fractional distillation is used for separating miscible liquids through the use of the different vapor pressure properties of the liquids. As the mixture is heated up, components start to vaporize according to their boiling points. The component with the least boiling point vaporizes first while the component with the highest boiling point vaporizes last.
This means that methanol would vaporize at the first fraction because it has the lowest boiling point followed by ethanol at the second fraction and then propan-1-ol at the last fraction.
This is a science question.

Isopropyl alcohol is a liquid with a density of 0.785 g/cm^3. How much volume would be taken up be 50.0 grams of isopropyl alcohol
Answer:
63.94 cm³Explanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\ [/tex]
From the question we have
[tex]volume = \frac{50}{0.785} \\ = 63.694267...[/tex]
We have the final answer as
63.94 cm³Hope this helps you

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.

A given mass of gas in a rigid container is heated from 100 °C to 300 °C. Which of the following best describes what will happen to the pressure of the gas? The pressure will
Taking into account the Gay-Lussac's Law, the pressure will increase by a factor less than three.
Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions against the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.
In summary, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.
Mathematically, Gay-Lussac's law indicates that the ratio of pressure to temperature is constant:
[tex]\frac{P}{T} =k[/tex]
Studying two different states, an initial state 1 and a final state 2, it is satisfied:
[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]
In this case, a given mass of gas in a rigid container is heated from 100 ° C to 300 ° C, that is, it is heated from 373 ° K to 573 ° K. This indicates that the temperature is increasing by a factor less than three. Since pressure is directly proportional to temperature, pressure must increase in the same proportion.
Finally, the pressure will increase by a factor less than three.

https://brainly.com/question/4147359?referrer=searchResultslonic bonds tend to form between two atoms with what characteristics?
Answer:Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable. Ionic compounds are typically neutral. Therefore, ions combine in ways that neutralize their charges.
Explanation:
Ionic bonds tend to form between two atoms with a high electronegativity difference.
Explanation:
An Ionic bond is defined as a chemical bond in which the complete transfer of electrons occurs from one atom to another.The transfer of electrons occurs from less electronegative atom to highly electronegative atomThe high electronegativity difference between the atomsCompounds with ionic bonds categorized as ionic compoundsSo, from this, we can conclude that ionic bonds tend to form between two atoms with a high electronegativity difference.
