Answer:

Explanation:

1.The color of the powder of a mineral.

                      Answer 1 : Streak

Streak is the color displayed by a mineral in powdered form. The streak of some minerals differs from their original color.

2.The sinking of one lithospheric plate beneath another.

                     Answer 2 : Subduction

At a convergent margin, a denser lithospheric plate falls beneath the lighter one in a process called subduction. This region is called the subduction zone.

3.A process that includes both the disintegration and decomposition of surface rock material.

                    Answer 3: Weathering

Weathering is defined as the physical disintegration and chemical decomposition of rocks to form soils and sediments on the earth surface.

4.The chemical altering of the composition of the material.

                    Answer 4: Chemical weathering  

It is the decomposition or altering of earth materials chemically.

5. How much matter is in a certain amount of space; mass divided by volume.

                     Answer 5 : Density

Density is defined as the mass per unit volume.

6. The physical or mechanical breakdown of Earth's materials.

                     Answer 6: Physical weathering

Physical weathering is the disintegration of earth materials using mechanical means.

7. Movement of Earth's materials by glacial action.

                         Answer 7: Glacial erosion

This is the wearing and washing away of earth's materials by action of moving glaciers.

8. The ability of a mineral to resist scratching.

                        Answer 8: Hardness

Hardness is expressed in an ability to resist deformation and any from of abrasion

             

9. A type of igneous rock that forms inside the Earth.

                       Answer 9: Plutonic or intrusive igneous rocks

Igneous rocks that forms within the crust are called plutonic or intrusive igneous rocks.

10. The rock formed by the cooling and solidifying of molten rock.

                     Answer 10: Igneous rocks

Igneous rocks are rocks that formed from cooling and solidifying of molten rocks

Which of these are ionic compounds? Check all that apply.
SIZIF [17.4K]
I think the correct answers from the choices listed above are the first, third and the last option. Ionic compounds are compounds that dissociates into ions when in aqueous solution. From the list, NH4Cl, KF and MgO are the ionic compounds. Hope this answers the question.

Given the following data:N2(g) + O2(g)→ 2NO(g), ΔH=+180.7kJ2NO(g) + O2(g)→ 2NO2(g), ΔH=−113.1kJ2N2O(g) → 2N2(g) + O2(g), ΔH=−163
statuscvo [17]

Answer:

ΔH = +155.6 kJ

Explanation:

The Hess' Law states that the enthalpy of the overall reaction is the sum of the enthalpy of the step reactions. To do the addition of the reaction, we first must reorganize them, to disappear with the intermediaries (substances that are not presented in the overall reaction).

If the reaction is inverted, the signal of the enthalpy changes, and if its multiplied by a constant, the enthalpy must be multiplied by the same constant. Thus:

N₂(g) + O₂(g) → 2NO(g) ΔH = +180.7 kJ

2NO(g) + O₂(g) → 2NO₂(g) ΔH = -113.1 kJ

2N₂O(g) → 2N₂(g) + O₂(g) ΔH = -163.2 kJ

The intermediares are N₂ and O₂, thus, reorganizing the reactions:

N₂(g) + O₂(g) → 2NO(g) ΔH = +180.7 kJ

NO₂(g) → NO(g) + (1/2)O₂(g) ΔH = +56.55 kJ (inverted and multiplied by 1/2)

N₂O(g) → N₂(g) + (1/2)O₂(g) ΔH = -81.6 kJ (multiplied by 1/2)

------------------------------------------------------------------------------------

N₂O(g) + NO₂(g) → 3NO(g)

ΔH = +180.7 + 56.55 - 81.6

ΔH = +155.6 kJ

Why does a star expand into a red giant?​
devlian [24]

Answer:

"Hydrogen is still available outside the core, so hydrogen fusion continues in a shell surrounding the core. The increasingly hot core also pushes the outer layers of the star outward, causing them to expand and cool, transforming the star into a red giant."
