Answer :
(a) The rate of formed is, 0.066 M/s
(b) The rate of formed is, 0.033 M/s
Explanation : Given,
= 0.066 M/s
The balanced chemical reaction is,
The rate of disappearance of =
The rate of disappearance of =
The rate of formation of =
As we know that,
= 0.066 M/s
(a) Now we have to determine the rate of formed.
The rate of formed is, 0.066 M/s
(b) Now we have to determine the rate of molecular oxygen reacting.
The rate of formed is, 0.033 M/s
45 molecules of chlorine gas (Cl₂) are needed to react with 30 atoms of aluminum (Al)
The balanced equation for the reaction is given below:
2Al + 3Cl₂ —> 2AlCl₃
From the balanced equation above,
2 atoms of Al required 3 molecules of Cl₂.
With the above information, we can determine the number of molecules of Cl₂ needed to react with 30 atoms of Al. This can be obtained as follow:
From the balanced equation above,
2 atoms of Al required 3 molecules of Cl₂.
Therefore,
30 atoms of Al will require = = 45 molecules of Cl₂.
Thus, 45 molecules of chlorine gas (Cl₂) are needed to react with 30 atoms of aluminum (Al)
