C6H8 + 8O2 ===> 6CO2 + 4H2O ... balanced equation
moles hexane = 54.3 g x 1 mol/80 g = 0.679 moles
moles O2 = 78.5 g x 1 mol/32 g = 2.45 moles
Limiting reactant is Oxygen (O2) since need 8 x as much as C6H8
Theoretical yield of CO2 = 2.45 mole O2 x 6 mole CO2/8mole O2 = 1.84 moles CO2
1.84 moles CO2 x 44 g/mol = 80.9 g (answer to 3 sig figs)
depending on if your question possesses this values
The volume of CO= 2.912 L
<h3>Further explanation
</h3>
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
Answer:
The answer is C which is 8 neutrons
Explanation:
This is because all carbon isotopes have 6 protons in their nucleus. Carbon 14 have 2 extra neutron aside from only having 6. So 6 protons + 6 neutrons + 2 more extra makes 14 which makes it Carbon - 14. I hope this makes sense.
1 FeI3 + 3 NaOH = 1 Fe(OH)3 + 3 NaI
FeI3 = 1
NaOH = 3
Fe(OH)3 = 1
NaI = 3
hope this helps!
