The charge of an aluminum ion is typically 3+. This is because the element's atomic number is 13, reflecting the fact that it has 13 electrons and 13 protons. The valence shell of aluminum has three electrons, and per the octet rule, these three electrons are lost resulting in just 10 electrons and 13 protons.
300 degrees Kelvin = 300 - 273 = 27 degrees Celsius.
So what you need to do is find out how many degrees Fahrenheit that is.
F = 9/5(27) + 32
F = 48.6 + 32
F = 80.6
You are at 55oF. You need to go from 55 to 80.6 or 25.6 degrees F.

Answer:
It becomes an ion
Explanation:
The element it took from becomes a positive ion
And chlorine becomes a negative ion
Answer:
T > 1250K
Explanation:
A reaction is thermodynamically favorable when ΔG° is < 0
ΔG° is defined as:
ΔG° = ΔH° - TΔS°
As ΔG° must be < 0:
TΔS° > ΔH°
As ΔHº=+50kJ and ΔSº=+40J/K:
T×40J/K > 50000J
T > 50000J / 40J/K
<em>T > 1250K</em>

Answer:
Therefore, it can be said that sugar molecules whether in crystal or cube form do not dissolve in ice tea.
Explanation:
Sugar molecules easily dissolve in warm or hot tea. However, in iced tea sugar does not dissolve it does not matter whether you use sugar cubes or sugar crystals.
This happens because of the entropy. The entropy of warm water is high as it has fast-moving molecules, whereas the entropy of ice water is negligible. hence, sugar molecules do not dissolve in ice tea.
Therefore, it can be said that sugar molecules whether in crystal or cube form do not dissolve in ice tea.
