Answer:

The answer to your question is KNO₃ is soluble and Fe(OH)₃ is insoluble.

Explanation:

Data

Potassium hydroxide (KOH)

Iron nitrate Fe(NO₃)₃

Double displacement reaction

3KOH + Fe(NO₃)₃ ⇒ 3KNO₃ + Fe(OH)₃

Conclusion

KNO₃ is soluble because compounds containing alkali metals ions are

soluble and also compounds containing nitrate ion are soluble.

Fe(OH)₃ is insoluble because compounds containing OH are insoluble

except Ba(OH)₂

6. Identify the number of neutrons in one atom of silicon with an isotopic mass number of 28 amu.

Sholpan [36]

Explanation:

The number of neutrons in one atom of silicon with an isotopic mass number of 28amu is 14.

An atom is made up three fundamental sub-atomic particles which are:

Protons, neutron and electrons

Protons are the positively charged particles in an atom

Neutrons do not carry any charges

Electrons are the negatively charged particles.

In the nucleus of an atom, both protons and neutrons can be found. They are the massive particle in an atom.

The mass number of an atom = number of protons + number of neutrons

Number of neutrons = mass number - number of protons.

From the periodic table, we know that silicon has an atomic number of 14.

The atomic number is the number of protons in an atom:

Number of neutrons = 28 - 14 = 14amu

In the atom, we will have 14amu of neutrons in a silicon atom.

Which of the following is NOT a subatomic particle?<br> Proton, Electron, Isotope or Neutron?

Free_Kalibri [48]

An isotope is the name for a type of an atom (depends on how many neutrons the atom has), so an isotope is not a subatomic particle

8. How are convection currents in the mantle (geosphere) and in the oceans (hydrosphere) similar? How are they different? Answer

jenyasd209 [6]

Answer:

Mantle convection is the slow creeping motion of Earth's rocky mantle caused by convection currents carrying heat from the interior of the earth to the surface while convection current in ocean in; Solar radiation affects the oceans: warm water from the Equatortends to circulate toward the poles, while cold polar water heads towards the Equator. The surface currents are initially dictated by surface wind conditions. The trade winds blow westward in the tropics, and the westerlies blow eastward at mid-latitudes. This wind pattern applies a stress to the subtropical ocean surface with negative curl across the northern hemisphere, and the reverse across the Southern Hemisphere. The resulting Sverdrup transport is equator ward.Because of conservation of potential vorticity caused by the poleward-moving winds on the subtropical ridge's western periphery and the increased relative vorticity of poleward moving water, transport is balanced by a narrow, accelerating poleward current, which flows along the western boundary of the ocean basin, outweighing the effects of friction with the cold western boundary current which origniates from high latitudes
