Moles Fe₂O₃ produced : 1.16 moles
<h3>Further explanation</h3>
Given
2.32 moles of iron
Required
moles of Fe2O3
Solution
The reaction coefficient in a chemical equation shows the mole ratio of the reacting compounds (reactants and products)
Reaction
4 Fe + 3 O₂ ⇒ 2 Fe₂O₃
From the equation, mol ratio Fe : mol Fe₂O₃ = 4 : 2, so mol Fe₂O₃ :
= 2/4 x mol Fe
= 2/4 x 2.32
= 1.16 moles
Structural formula of a molecule shows:
a. the arrangement of bonded atoms
b. the number of ionic bonds
c. the number of metallic bonds
d. the shapes of molecular orbitals
He should transfer the food to another cooler.
This is because for a refrigerator, the temperature should be kept at 40 degrees Fahrenheit in order to slow down the development of the spoilage bacteria that develop in food in the form of color or odor.
Answer:
c. 3.00 M HCl
Explanation:
From dilution formula
C1V1 = C2V2
C1=?, V1= 10.0ml, C= 1.5, V2= 20.0ml
Substitute and Simplify
C1×10= 1.5×20
C1= 3.00M
