Answer: A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.
Explanation:
A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.
Explanation:
The chart below shows monatomic ions formed when an atom loses or gains one or more electrons, and the ionic compounds they form. You can check your periodic table to see that the cations are monatomic ions formed from metals, and the anions are monatomic ions formed from nonmetals.
The volume of the gas will be 1 L at a height of 6.5 km.
Since temperature is constant, we can use <em>Boyle’s Law</em>.
<em>p</em>₁<em>V</em>₁ = <em>p</em>₂V₂
p<em>₂</em> = <em>p</em>₁ × <em>V</em>₁/<em>V</em>₂ = 500 mL × (1 atm/0.5 atm) = 1000 mL = 1 L
According to this formula, when:
ΔG = ΔH - T*ΔS
when the reaction is thermodynamically spontaneous ΔG < 0
∴ ΔH - T* ΔS = 0
∴T*ΔS = ΔH
∴ T = ΔH / ΔS
when we have:
ΔH = -70KJ
and ΔS = -0.4 KJ/K
So by substitution:
T = -70KJ /- 0.4
= 175 K
∴the certain temperature below which the reaction will be thermodynamically spontaneous is 175 K
Answer:
The Sun's temperature, which reaches around 15 million degrees Celsius in its core, steadily decreases with distance from the core, falling to 6000°C at its 'surface'. ... Instead, it rises to about 10,000°C in the chromosphere, and exceeds a million degrees Celsius in the corona.
