Answer:
H₂O = 3.56 moles
MgCl₂ = 1.78 moles
Explanation:
Given data:
Moles of HCl = 3.56 mol
Moles of water produced = ?
Moles of MgCl₂ produced = ?
Solution:
Chemical equation:
2HCl + Mg(OH)₂ → MgCl₂ + 2H₂O
Now we will compare the moles of HCl with water and magnesium chloride.
HCl : MgCl₂
2 : 1
3.56 : 1/2×3.56 = 1.78 mol
HCl : H₂O
2 : 2
3.56 : 3.56 mol
The volume of CO= 2.912 L

Given
Dehydration of 6 g of methanoic acid with H2SO4
Required
The volume of CO
Solution
Reaction
HCOOH ⇒ CO+H₂O
MW = 1.Ar C+2.Ar H+2.Ar O
MW = 1.12+2.1+2.16
MW= 46 g/mol
mol = mass : MW
mol = 6 g : 46 g/mol
mol = 0.13
From equation, mol ratio HCOOH : CO, so mol CO = 0.13
Vm = 22.4 L
so for 0.13 mol :
= 0.13 x 22.4 L
= 2.912 L
For my 8th grade science fair I built a Newton's Cradle. It was really cool!! I'm a procrastinator too but I was able to knock it out the day before. It's a great demonstration of the laws of motion.(physics)
