The correct answer is NH₄Cl.
With the increase in temperature, endothermic reactions are favored. The dissolution of NH₄Cl in water is an example of an endothermic reaction. When the temperature is increased more dissolution of the salt takes place, thus, the solubility of the salt increases.
Hence, it can be said that NH₄Cl will exhibit the greatest change in the solubility per 100 g solvent with an elevation in temperature.
Answer:
The density is 2.5625g/mL. Hope this helped! :)
Explanation:
M= 8.2g D=M/V
V= 28.3-25.1=3.2mL
D=8.2g/3.2mL
D= 2.5625g/mL
Answer:
43%
Explanation:
As the problem says that the antimony has only two isotopes, lets call each isotope the following:
x=abundance of isotope 121Sb
1-x=abundance of isotope 123Sb
And
Atomic weight of antimony = (isotopic mass of 121Sb*x)+(isotopic mass of 123Sb*(1-x))
Replacing values we have:
Solving for x:
it means that the abundance of the isotope 121Sb is 57% and the abundance of isotope 123Sb is 43%
If you round the days hours to 24 then multiply 7 you get 168, and then if you multiply 1.2 you would get 201.6
so the answer would be 201.6 ml an hour
Answer:
Waves carry energy from place to place.
Explanation:
Some waves are used for mainly communication and phone signals. They help people get internet in the middle of nowhere if you are near an energy wave.
