The theoretical yield of iron metal : 16.418 g
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
2 Fe₂O₃ + 3 C ⇒ 4 Fe + 3 CO₂
mol Fe₂O₃ (MW=159,69 g/mol) :
mol Fe₂O₃ : mol Fe = 2 : 4
mol Fe :
mass Fe(the theoretical yield) :
The atmosphere of the early earth had high concentrations of carbon dioxide due to the volcanic activity at this time in the earth's development. The atmospheric concentration of oxygen only began to increase with the appearance of the first types of photosynthetic organisms. These organisms used energy from the sun, water and carbon dioxide to make food. Oxygen was a byproduct of this reaction.
What two substances are always produced by a neutralization reaction? water and salt
Answer:
the equilibrium composition Kp is 3471.01
Explanation:
Given;
H₂ + ½O₂ ↔ H₂O
Using Gibb's formula;
---------(i)
where;
ΔG(T) is change in Gibb's energy and it is given as;
= 1(-241,820 + 82,593 -9904 - 2000 x 264.571) - 1(0 + 61,400 - 8468 - 2000 x 188.297) - 0.5(0 + 67,881 -8682 - 2000 x 268.655)
= -698273 + 323662 + 239055.5
= -135,555.5 KJ
Substituting this value into equation (i)
Therefore, the equilibrium composition Kp is 3471.01
