Answer: The correct answer is A
Explanation:
On addition of the ammonium nitrate to 50 ml of water the temperature decreases which means that reaction between the ammonium nitrate and water is an endothermic reaction.The value of is positive for an endothermic reactions.
Entropy is a degree of randomness of the system.
On addition of the ammonium nitrate to water ammonium nitrate break down into ions which means that entropy is increased.
(Gibb's free energy)
Since, ammonium nitrate is getting dissolved in water which means that this reaction is spontaneous and of spontaneous reaction is negative that is:
Answer:
6. IDK, google only says glacial erratics
7. Deposition
8. Building landfills, I think
Explanation:
sodium only has one valence electron meaning that there is only one electron in the outer rim. so it will go... 1st energy lvl=2 electrons. 2nd energy lvl=8 electrons. and, 3rd energy lvl=1 electron.

Ranking order of speed of sound is; Steel >Water > Air.
Speed of sound in normal air is 340 m/s, in water the speed is 1,430 m/s and in steel the speed is 5920 m/s.
<h3>What is speed of sound?</h3>
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. The speed of sound in an ideal gas depends only on its temperature and composition. The speed of sound in mathematical notation is conventionally represented by 'c'. The speed of sound is variable and depends on the properties of the substance through which the wave is travelling.
