Answer:
4.13 moles of Fe
Explanation:
Step 1: Write the balanced equation
3 CO + Fe₂O₃ ⇒ 2 Fe + 3 CO₂
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of CO to Fe is 3:2.
Step 3: Calculate the moles of Fe formed from 6.20 moles of CO
We will use the previously established molar ratio.
6.20 mol CO × 2 mol Fe/3 mol CO = 4.13 mol Fe
Answer:
<h2>
2Al +
3CuO ==>
3Cu + Al2O3</h2>
Explanation:
So let's break this chemical equation down into 2 parts - Reactants and Products
Reactants = Al + CuO
Products = Cu + Al2O3
So the Chemical Reaction will be
Al + CuO ==> Cu + Al2O3
So the balanced equation will be,
2Al + 3CuO ==> 3Cu + Al2O3

Answer:
The Mycelium is usually hidden in the soil, in wood, or another food source. A Mycelium may fill a single ant or cover many acres.
At STP (standard temperature and pressure conditions), 1 mol of any gas occupies 22.4 L
This rule is applied to O₂
22.4 L volume occupied by 1 mol
Therefore 83.4 L occupied by - 1/ 22.4 x 83.4 = 3.72 mol
stoichiometry of O₂ to H₂O is 1:2
then the number of moles of water produced - 3.72 mol x 2= 7.44 mol
mass of water produced - 7.44 mol x 18.01 g/mol = 134.1 g
correct answer is D
