Answer:
The answer to your question is limiting reactant = Fe
Explanation:
Data
moles of Fe = 2
moles of O₂ = 6
Process
1.- Write the balanced chemical reaction
Fe + O₂ ⇒ Fe₂O₃
Reactants Elements Products
1 Fe 2
2 O 3
4Fe + 3O₂ ⇒ 2Fe₂O₃
Reactants Elements Products
4 Fe 4
6 O 6
2.- Use the balanced chemical reaction to determine the limiting reactant.
Theoretical proportion of reactants 4 moles Fe / 3 moles O₂ = 1.33
Experimental proportion of reactants = 2 moles Fe/6 moles O₂ = 0.333
3.- Conclusion
As the experimental proportion was lower than the theoretical we conclude that the amount of Fe was lower in the experiment which is the limiting reactant.
Answer:
The initial temperature of helium was T1 = 232.23 K
Explanation:
Given data:
Initial volume V1 = 5 L
Initial pressure P1 = 699 mmHg
Final pressure P2 = 800 mmHg
Final volume V2 = 5.7 L
Final temperature T2= 303 K
Initial temperature T1 = ?
Solution:
Formula:
P1V1/T1 = P2V2/T2
T1 = T2 × P1V1/P2V2
T1 = 303 K × 699 mmHg × 5 L / 800 mmHg × 5.7 L
T1 = 1058985/ 4560
T1 = 232.23 K
initial temperature of helium was 232.23 k.
Answer: The octet rule is a chemical rule of thumb that reflects the observation that main group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
Explanation:
Answer:
So the balanced chemical equation would look like this:
4NO + 6O -> 4N + 5
sorry i dont k how to find the moles when im already given a value :(
