H > 6,000
height greater than 6,000
Molar mass KI = 166.0028 g/mol and Pbl₂ = 461.0089 g/mol
2 Kl + Pb(NO₃)₂ ------> 2 KNO₃ + Pbl₂
2 x 166.0028 g ---------> 461.0089 g
? g KI -------------> 1.2 g
Mass KI = 1.2 x 2 x 166.0028 / 461.0089
Mass KI = 398.40672 / 461.0089
<span>Mass KI = </span>0.86 g

A size dependent property is a physical property that changes when the size of an object changes.
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>
