They share four electrons, two from each oxygen atom
I think it’s 5000 because it says that their is over 4,124 valid species of minerals.
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:
The answer is A (The ability to react with oxygen)
