Answer:
easy bro. So i also don't know.
The moles of oxygen produced is calculated as follows
write a balanced reacting equation, that is
Mg(ClO3)2 ---->MgCl2 + 3O2
from the equation above the reacting ratio of Mg(ClO3)2 to O2 is 1: 3 therefore the moles of O2 produced = 5.12 moles x3 =15.36 moles
Answer:
2.1 M is the molarity of the HCl solution.
Explanation:
Molarity of HCl solution =
Volume of HCl solution =
Ionizable hydrogen ions in HCl =
Molarity of NaOH solution =
Volume of NaOH solution =
Ionizable hydroxide ions in NaOH =
(neutralization )
2.1 M is the molarity of the HCl solution.
Answer is: mass of calcium hydroxide is 46.98 grams.
Balanced chemical reaction: CaO + H₂O → Ca(OH)₂.
m(CaO) = 35.55 g.
n(CaO) = m(CaO) ÷ M(CaO).
n(CaO) = 35.55 g ÷ 56 g/mol.
n(CaO) = 0.634 mol; limiting reactant.
m(H₂O) = 125 mL · 1.000 g/mL.
m(H₂O) = 125 g.
n(H₂O) = 125 g ÷ 18 g/mol.
n(H₂O) = 6.94 mol.
From chemical reaction: n(CaO) : n(Ca(OH)₂) = 1 : 1.
n(Ca(OH)₂) = 0.634 mol.
m(Ca(OH)₂) = 0.634 mol · 74.1 g/mol = 46.98 g.
Answer:
PV=nRT
Explanation:
Assuming it is an Ideal gas, You are going to make Pressure here the subject of formula and input it into Dalton's law of Partial pressure. Ptotal = P1 + P2 + P3 ............
