Answer:
0.427 g HClO4
Explanation:
[H+]= 10^-3.3 = 5.01 x 10^-4 M
8500 mL=8.5 L
M= mol solute/ L solution
mol solute= M* L solution
mol solute= (5.01 x 10^-4 M * 8.5 L)
mol solute= 4.26 x 10^3 mol HClO4
1 mol HClO4 -> 100. 4 g
4.26 x 10^3 mol HClO4 -> x
x=0.427 g HClO4
Answer:
Kc = 1.55
Explanation:
This is the reaction:
2H₂O (g) ⇄ 2H₂(g) + O₂(g)
Eq. 0.250M 0.360M 0.750M
The expression for Kc is.
Kc = [O₂] . [H₂]² / [H₂O]²
Kc = 0.750 . 0360² / 0.250²
Kc = 1.55
Answer:
This one is easy. It's the Avogadros' Hypothesis or Avogadros' Law, where the equal volumes of gases in SAME conditions have an equal amount of molecules!
Answer:
C
Explanation:
Polar molecules combine with polar molecules ( like combines with like)
Answer:
9.9 ml of 0.200M NH₄OH(aq)
Explanation:
3NH₄OH(Iaq) + FeCl₃(aq) => NH₄Cl(aq) + Fe(OH)₃(s)
?ml of 0.200M NH₄OH(aq) reacts completely with 12ml of 0.550M FeCl₃(aq)
1 x Molarity NH₄OH x Volume Am-OH Solution(L) = 2 x Molarity FeCl₃ x Volume FeCl₃ Solution
1(0.200M)(Vol Am-OH Soln) = 3(0.550M)(0.012L)
=> Vol Am-OH Soln = 3(0.550M)(0.012L)/1(0.200M) = 0.0099 Liter = 9.9 milliliters
