Explanation:
Once solid ammonium nitrate interacts with water, the molecules of polar water intermingle with these ions and attract individual ions from the structure of the lattice, that actually will break down. E.g;-NH4NO3(s) — NH4+(aq)+ NO3-(aq) To split the ionic bonds that bind the lattice intact takes energy that is drained from the surroundings to cool the solution.
Some heat energy is produced once the ammonium and nitrate ions react with the water molecules (exothermic reaction), however this heat is far below that is needed by the H2O molecules to split the powerful ionic bonds in the solid ammonium nitrate.
Hence, we can say that the dissolution of ammonium nitrate in water is highly endothermic reaction.
After that have been up for a while thay are metal
Answer:
B)The octet of carbon atom remains incomplete in the molecule.
Explanation:
Answer:
B. Hypothesis
Explanation: A hypothesis is a guess of what will or might happen before an experiment.
Answer:
The temperature of the town will be 15°F.
The equation showing the final temperature after drop say x degrees can be written as:

Explanation:
The current temperature in our town = T = 31°F
Temperature drop suggested by radio announcer = 15°
Temperature of the town after temperature drop = T'


The equation showing the final temperature after drop say x degrees can be written as:
