4FeS₂ + 11O₂ → 2Fe₂O₃ +8SO₂
What happen if FeS₂ is added to the reaction is that
The reaction will shift in the direction of the products
<u><em>Explanation</em></u>
- FeS₂ is a reactant in reaction above .
- When more of reactant added to a system at equilibrium, it increases the concentration of reactant molecules.
- According to collision theory,this increase the number of collisions per second of reactant molecule and therefore more product is formed.
Answer:
The volume of nitrogen gas at STP is 55.1 liters
Answer:
ΔH°_rxn = -195.9 kJ·mol⁻¹
Explanation:
4NH₃(g) + 3O₂(g) ⟶ 2N₂(g) +6H₂O(g)
ΔH°_f/(kJ·mol⁻¹): -45.9 0 0 -241.8
The formula relating ΔH°_rxn and enthalpies of formation (ΔH°_f) is
ΔH°_rxn = ΣΔH°_f(products) – ΣΔH°_f(reactants)
ΣΔH°_f(products) = -6(241.8) = -1450.8 kJ
ΣΔH°_f(reactants) = -4(45.9) = -183.6 kJ
ΔH°_rxn = (-1450.8 + 183.6) kJ = -1267.2 kJ
Tectonic plates are key to the rock cycle as their motions result in processes that are important to the rock cycle, therefore they play a major role in the rock cycle
