Explanation:
A substance that completely dissociates into ions when dissolved in its aqueous solution is known as a strong electrolyte.
Whereas a substance that does not dissociate into ions is known as a non-electrolyte.
If a substance partially dissociates into ions when dissolved in its aqueous solution then it is known as a weak electrolyte.
(a)
As there is occurring no dissociation. Hence, no formation of ions takes place therefore, it is a non-electrolyte.
(b)
As partial dissociation of ions take place in this reaction as the reaction is in equilibrium state. Hence, it is a weak electrolyte.
(c)
Here, complete dissociation of ions is taking place as the reaction is not in an equilibrium state. Therefore, it is a strong electrolyte.
(d)
Here also complete dissociation is taking place. Hence, it is a strong electrolyte.
(e)
As there is occurring no dissociation. Hence, no formation of ions takes place therefore, it is a non-electrolyte.
Oxigen acts like as the final electron acceptor at the end of the electron transport chain
Answer:
The coefficient of O2 is 11
Explanation:
Step 1:
The equation for the reaction:
FeS2 + O2 → SO2 + Fe2O3
Step 2:
Balancing the equation. The equation can be balance as follow:
FeS2 + O2 → SO2 + Fe2O3
There are 2 atoms of Fe on the right side and 1 atom on the left. It can be balance by putting 2 in front of FeS2 as shown below:
2FeS2 + O2 → SO2 + Fe2O3
There are 4 atoms of S on the left side and 1 atom on the right side. It can be balance by putting 4 in front of SO2 as shown below:
2FeS2 + O2 → 4SO2 + Fe2O3
Now, there are a total of 11 atoms of O on the right side and 2 atoms on the left side. It can be balance by putting 11/2 in front of O2 as shown below:
2FeS2 + 11/2O2 → 4SO2 + Fe2O3
Multiply through by 2 to clear the fraction as shown below:
4FeS2 + 11O2 → 8SO2 + 2Fe2O3
Now the equation is balanced.
The coefficient of O2 is 11
Answer:
Both have the same amount of particles.
Explanation:
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ particles.
This implies that 1 mole of Hydrogen contains 6.02×10²³ particles. Also, 1 mole of oxygen contains 6.02×10²³ particles.
Thus, 1 mole of Hydrogen and 1 mole of oxygen contains the same number of particles.
