Answer:
A) 2.2 mol
Explanation:
Given data:
Number of moles of O₂ produced = ?
Number of moles of N₂O₅ decomposed = 4.3 mol
Solution:
Chemical equation:
2N₂O₅ → 4NO₂ + O₂
Now we will compare the moles of N₂O₅ and O₂.
N₂O₅ : O₂
2 : 1
4.3 : 1/2×4.3 = ×2.2
Thus, from 4.3 moles of N₂O₅ 2.2 moles of O₂ are produced.
Answer:the first column has one valance electron the second has 2 and so on.
The only exception is helium that has 2.
Explanation:
Answer:
<h2>The answer is 1.99 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of acid = 60.19 g
volume = 30.2 mL
The density is
We have the final answer as
<h3>1.99 g/mL</h3>
Hope this helps you
Hydrogen bond is your answer. Be careful with covalent bonds! The force within a molecule between hydrogen and fluorine, nitrogen, or oxygen may be a covalent bond, but the problem said "intermolecular forces," in which a covalent bond is not a type of force.
Answer:
Partial pressure of Ne is 0.61 atm.
Explanation:
Mole fraction of a gas in mixture = (no. of moles of the gas in mixture)/(total no. of moles of gases in mixture)
Here, total no. of moles of gases = (0.32 + 0.56) moles = 0.88 moles
So, mole fraction of Ne in mixture,
Let's assume both He and Ne along with their mixture behaves ideally,
Hence, in accordance with Dalton's law of partial pressure-
Where, and are partial pressure of Ne and total pressure respectively.
So,
So, partial pressure of Ne is 0.61 atm.
