It is approximately 10 ^ -10
Answer:
3.75 atm
Explanation:
Volume remains constant, so we can use <em>Gay-Lussac’s Law</em>.
<em>p</em>₁/<em>T</em>₁ = <em>p</em>₂/<em>T</em>₂ Multiply both sides by <em>T</em>₁
<em>p</em>₁ = <em>p</em>₂ × <em>T</em>₁/<em>T</em>₂
<em>p</em>₁ = ?; <em>T</em>₁ = 299 K
<em>p</em>₂ = 7.77 atm; <em>T</em>₂ = 620 K Insert the values
<em>p</em>₁ = 7.77 × 299/620 Do the operations
<em>p</em>₁ = 3.75 atm
Answer:
The configuration of the atom would be 2-8-2.
Explanation:
Any atom of an element combines with other element to complete its octet and become stable.
The electron configuration of the given atom is 2-8-6. That means the atom has 6 electrons in its outermost shell. To become stable the atom should have 8 electrons in its outermost shell. The given atom has 6 electrons so it either lose 6 electrons or gain 2 electrons to complete its octet.
But we know the atom having 5,6,7 electrons in its outermost shell they do not lose, they gain either 3 or 2 or 1 electrons to complete its octet.
So we say that atom with the electron configuration 2-8-6 bond with the atom having electron configuration 2-8-2.
Answer:
1 mol
Explanation:
2H2 + O2 ---> 2H2O
4g H2 (1 mol H2/ 2g H2)(1 mol O2/ 2 mol H2)= 1mol O2
