he solution is said to be an ideal solution, only when the intermolecular forces of attraction between A-A, B- B and A- B are ne
KengaRu [80]

Answer:True

Explanation:

A ideal solution is a solution which obeys Raoults law on almost every concentration and temperature range.

Ideal solutions are formed by mixing those solute and solvent which has identical molecular properties.

Lets take A be the solute and B be the solvent  so to form a ideal solution from these components the solute-solute(A-A) molecular interaction and  solvent -solvent (B-B) molecular interactions must be identical with the solute solvent interaction(A-B).

The solute-solute molecular interaction ,solute-solvent molecular interaction and solvent-solvent molecular interaction must be equal in order to form a ideal solution.

The enthalpy of mixing and volume of mixing of ideal solution is zero.

enthalpy of mixing is the amount of energy released on mixing a solute and solvent and in case  of ideal solutions it is zero.

Volume of mixing is change in volume on mixing a solute and solvent.

How does the principle of electromagnetism explain the interaction between Earth’s magnetic field and the solar wind?
Otrada [13]

Answer:

Electromagnetism studies the attraction of two bodies within a magnetic field.

Electromagnetic interaction is one of the four fundamental forces of the known universe. The charged particles interact electromagnetically through the exchange of photons. Experimentally it was concluded that the lines of force of magnetic fields were always closed, eliminating the possibility of a magnetic monopole, so that within a magnetic field there are two poles, in the solar system the attraction between earth and wind Solar is by means of a field.

The most correct theory on this topic is the Earth itself is protected from the solar wind by its magnetic field, most of those charged particles, and most of those charged particles are trapped in the Van Allen radiation belt.

Explanation:

The magnetosphere or magnetosphere is a region around a planet in which its magnetic field deflects most of the solar wind, forming a kind of protective shield against high energy charged particles from the Sun. This magnetic or magnetosphere atmosphere does not It is only in the solar system, but also usually occurs on other planets such as jupiter and others (since it occurs on all planets with a magnetic field)

Compare the energy required to break the bonds of the reactants and the energy released when products form in an exorgonic react
const2013 [10]
When products form in an exergonic reaction, the <span>energy required to break bonds is less than the energy released from new bonds. This is usually given off as light. I hope this is the answer you are looking for. Looking forward to help you again. Have a great day ahead!</span>
