Answer: The balanced equation is .
Explanation:
A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.
For example,
Here, number of atoms on reactant side are as follows.
- V = 2
- O = 5
- Ca = 1
The number of atoms on product side are as follows.
- V = 1
- O = 1
- Ca = 1
In order to balance this equation, multiply Ca by 5 on reactant side. Multiply V by 2 and CaO by 5 on product side. Therefore, the equation can be rewritten as follows.
Now here, number of atoms on reactant side are as follows.
- V = 2
- O = 5
- Ca = 5
The number of atoms on product side are as follows.
- V = 2
- O = 5
- Ca = 5
Since, there are same number of atoms on both reactant and product side. So, the equation is now balanced.
Thus, we can conclude that the balanced equation is .
Answer:
30 moles of CO₂
Explanation:
balanced equation ,
CS₂+3O₂ → CO₂+2SO₂
From equation, 3 moles of O₂ are needed to make 1 mol of CO₂.
This means to produce 1 mol of CO₂, we need 3 moles of O₂, then how many moles of CO₂ will be produced from 90 moles of O₂ ?
Use unitary method to solve such problems,
Number of moles of CO₂ that will be produced:
=
=
= 30 moles of CO₂
