N has an electronegativity of 3.0
P has an electronegativity of 2.2
As has an electronegativity of 2.2
So N has the highest eectronegativity
Answer:
27.6mL of LiOH 0.250M
Explanation:
The reaction of lithium hydroxide (LiOH) with chlorous acid (HClO₂) is:
LiOH + HClO₂ → LiClO₂ + H₂O
<em>That means, 1 mole of hydroxide reacts per mole of acid</em>
Moles of 20.0 mL = 0.0200L of 0.345M chlorous acid are:
0.0200L ₓ (0.345mol / L) = <em>6.90x10⁻³ moles of HClO₂</em>
To neutralize this acid, you need to add the same number of moles of LiOH, that is 6.90x10⁻³ moles. As the LiOH contains 0.250 moles / L:
6.90x10⁻³ moles ₓ (1L / 0.250mol) = 0.0276L of LiOH =
<h3>27.6mL of LiOH 0.250M</h3>
Explanation:
The steps involved in formation of a sedimentary rock are placed in the correct order as follows.
Step 1: The sediment is deposited by wind, flowing water, or other natural processes.
Step 2: The sediment is gradually buried and compacted.
Step 3: Dissolved minerals completely cement the sediment together.
As a result, it leads to the formation of a sedimentary rock.
Answer
is: molar solubility of barium carbonate is 4.47·10⁻⁵ M.
Chemical
reaction:BaCO₃(s) →
Ba²⁺(aq) + CO₃²⁻(aq).
Ksp
= 2.0·10⁻⁹.
s(BaCO₃) = ?M.
s(BaCO₃) = s(Ba²⁺)
=s(CO₃²⁻) = x.
Ksp
= s(Ba²⁺) · s(CO₃²⁻).
Ksp
= x · x.
2.0·10⁻⁹ =
x².
x
= √2.0·10⁻⁹ = 4.47·10⁻⁵
