Balanced equation of potassium chloride and ammonium nitrate; it’s types, net and observation
ASHA 777 [7]

Potassium chloride reacts with ammonium nitrate to give ammonium chloride and potassium nitrate.

This is a type of double displacement reaction. The balanced chemical equation can be represented as,

KCl(aq)+NH_{4}NO_{3}(aq)-->NH_{4}Cl(aq)+KNO_{3}(aq)

Total ionic equation for this reaction will be,

K^{+}(aq)+Cl^{-}(aq)+NH_{4}^{+}(aq)+NO_{3}^{-}(aq)--> K^{+}(aq)+NO_{3}^{-}(aq)+NH_{4}^{+}(aq)+Cl^{-}(aq)

There is no apparent reaction as this reaction is not accompanied by the formation of a gas or a solid precipitate. We cannot observe any visual reaction as there is not net reaction taking place. All the ions remain as spectator ions.

If you help me, I will mark you as most Brilliance. I will also give you 5 Stars... !<br> .
pashok25 [27]

Answer:

It is c

Explanation:

  • This is due, for example, to the fact that when the Earth is closer to the Sun in its elliptical orbit it orbits faster, while when it is further away it orbits slower, averaging to a value equivalent to that of a circular orbit.
  • Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane – the plane of Earth's orbit around the sun.
  • While the Earth spins through space it stays almost up right on its axis, although as it spins through space it gives us seasons. One hemisphere, when faced directly to the sun has Summer, meanwhile the other the has Winter. Later on the hemispheres have Autumn and Spring.

Stars are formed from interstellar clouds because of
Triss [41]
The answer is D. Stars are formed from interstellar clouds because of the Law of Universal Gravitation. The interstellar clouds are termed as nebula. When other stars dies a supernova occurs then the gravity from this pushes matter into the clouds until it cannot overcome the gravitational pull and it collapses which heats matter up forming a star.
