First, you would add the products: 0.4 + 6.01 = 6.41 g
Then, to get the mass of Iron required, you would do 6.41 - 5.0 = 1.41
This is because in the conservation of mass principle it states,
mass of reactants = mass of products.
Answer:
Keq=0.866
Explanation:
Hello,
In this case, the undergone chemical reaction is:
In such a way, since 0.0055 mol of N₂O₄ remains in the flask, one infers that the reacted amount (
) was:
In addition, the produced amount of NO₂ is:
Finally, considering the flask's volume, the equilibrium constant is then computed as follows:
Best regards.
Answer:
C) Krypton is a noble gas, so it was difficult for chemists to find it, as though it was a secret.
Explanation:
<span>A) 2NaOH -> 2Na + O2 + H2
is not correct since Na is unstable
B) 2NaOH -> 2Na + H2O + 1/2O2
is not correct since Na is unstable
C) 2NaOH -> Na2O + H2O
is correct since N2O is stable
D) 2NaOH -> 2Na + H2O2
is not correct since Na is unstable</span>
