Answer:
Na is the element from the second period that has the largest atomic radius
Explanation:
The atomic radius is a chemist property from the periodic table. It is decreased when we move in a period from the periodic, so the element in the second period that has the largest radius is Na, and the shortest, the Ar
The atomic radius indicates the distance between the nucleus and the outermost valence layer. In the periods it decreases with increasing Atomic Number, to the right, due to the attraction that the nucleus exerts on the electrons of the outermost orbitals, thus decreasing the core-electron distance.
Answer:
Keqq = 310
Note: Some parts of the question were missing. The missing values are used in the explanation below.
Explanation:
<em>Given values: ΔH° = -178.8 kJ/mol = -178800 J/mol; T = 25°C = 298.15 K; ΔS° = -552 J/mol.K; R = 8.3145 J/mol.K</em>
Using the formula ΔG° = -RT㏑Keq
㏑Keq = ΔG°/(-RT)
where ΔG° = ΔH° - TΔS°
㏑Keq = ΔH° - TΔS°/(-RT)
㏑Keq = {-178800 - (-552 * 298.15)} / -(8.3145 * 298.15)
㏑Keq = -14221.2/-2478.968175
㏑Keq = 5.73674166
Keq = e⁵°⁷³⁶⁷⁴¹⁶⁶
Keq = 310.05
To let you know what you are working with. if you have a wrong name for a graph then you will get the wrong answer
Answer:
Why are redox reactions used in batteries? The attraction between charged ions releases energy. The movement of electrons creates an electric current. The reactions are extremely exothermic, producing an electric current.
Explanation:
Why are redox reactions used in batteries?
The attraction between charged ions releases energy.
The movement of electrons creates an electric current.
The reactions are extremely exothermic, producing an electric current.
The reactions are extremely endothermic, inducing the movement of electrons.
2 Al₂O₃ = 4 Al + 3 O₂
4 moles Al ----------> 3 moles O₂
11.0 moles Al -------> ?
O₂ = 11.0 * 3 / 4
= 8.25 moles of O₂
hope this helps you and have a great day!
