Answer: The balanced equation for the given reaction is
.
Explanation:
A chemical equation which contains same number of atoms on both reactant and product side.
For example,
Here, number of atoms on reactant side are as follows.
- S = 1
- O = 4
Number of atoms on product side are as follows.
- S = 1
- O = 3
To balance this equation, multiply by 2 on reactant side and multiply
by 2. Hence, the equation will be re-written as follows.
Here, number of atoms on reactant side are as follows.
- S = 2
- O = 6
Number of atoms on product side are as follows.
- S = 2
- O = 6
Now, there are same number of atoms on both reactant and product side. So, this equation is balanced.
Thus, we can conclude that the balanced equation for the given reaction is .
Answer:
V= 0.147 L
Explanation:
This is simply the application of combined gas law twice, to find the unknowns.
Combined gas law states that:
P= pressure of air
V= volume of air
n= moles of air
R= Universal gas constant ( 0.08205 L atm mol⁻¹ K⁻¹)
T= Absolute temperature in kelvin.
Now, applying the same gas law at 483K and substituting for n
V=
V= 0.147 L
