Iron produced : 1.5 kg
<h3>Further explanation</h3>
Reaction
a) CaCO3→CaO + CO2
b) CO2 + C → 2CO
c) Fe2O3 + 3CO → 2Fe + 3CO2
mol CaCO₃ (MW=100,0869 g/mol) :
mol CO₂ = mol CaCO₃ =13.39(reaction a)
mol CO = 2 x mol CO₂ = 26.78(reaction b)
mol CO(reaction c) = 1.5 mol CO from reaction b = 1.5 x 26.78 = 40.17
mol Fe(reaction c) = 2/3 x mol CO =
Or we can cancel out the same compound in different sides from the sum of the three reactions to find mol Fe
a) CaCO3→CaO + CO2
b) CO2 + C → 2CO
c) Fe2O3 + 3CO → 2Fe + 3CO2
----------------------------------------------+
CaCO3 + Fe2O3 + C + CO + 3CO2 ⇒ CaO + 2Fe
mol Fe = 2 x mol CaCO3 = 2 x 13.39 = 26.78
mass Fe :
all but energy i think but if not its a and d
Explanation:
Answer:Mole, also spelled mol, in chemistry, a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.
Explanation:
Answer:
The chances of the offspting being pink is 50%
<span>a)
</span>First order
in A and zero order in B
<span>ln [A]
= (ln 0.1) (2) + ln Ao = ln 0.01 + ln Ao = ln 0.01 Ao = 1.0% of A will remain</span>
<span>b)
</span>First
order in A and first order in B
<span>1/[A] – 1/[A]0= kt where t+=1 and k=9</span>
[A]/[A]=1/19=0.053=5.3%
<span>c)
</span>Zero
order in both A and B
<span>[A]0-[A] = kt</span>
Then at 2
hours [A]=0 All of it has reacted.
<span> </span>
