Actual yield of Fe2(So4)3 = 18.5g
2FePo4 + 3Na2SO4 -> Fe2(SO4)3 + 2Na3PO4
Mole of FePO4 = mass of it / its molar mass =
25 g / (55.8 + 31 + 16*4) = 0.166 mol
every 2 mole of FePO4 will form 1 mole of Fe2(SO4)3
Mole of Fe2(SO4)3 produced = 0.166 / 2 = 0.0829 mol
0.0829 * (55.8*2 + 3*(32.1+ 16*4)) = 33.148 g of Fe2(SO4)3
18.5 / 33.148 * 100 = 55.8%
Answer:
Explanation:
You calculate the energy required to break all the bonds in the reactants.
Then you subtract the energy needed to break all the bonds in the products.
2H₂ + O₂ ⟶ 2H-O-H
Bonds: 2H-H 1O=O 4H-O
D/kJ·mol⁻¹: 436 498 464
Answer:
Compound
Explanation:
The given specie is a compound.
A compound is made up of two or more kinds of atoms/elements joined together in a definite grouping.
- The properties of a compound are distinct and different from those of the individual elements that are combined in its make-up.
- For this given specie, the elements are carbon, hydrogen and oxygen.
- So, this is a compound.
Elements are distinct substances that cannot be split - up into simpler substances. Such substances consist of only one kind of atom
