CH4 + 2O2→CO2 + 2H2O
Explanation:
CH4 + O2→CO2 + H2O
First look at the C atoms. At first glance they are balanced with 1 C on each side.
Now look at the H atoms. They are not balanced. There are 4 H atoms on the left side and 2 H atoms on the right. Place a coefficient of 2 in front of the H2O. We now have 4 H atoms on both sides.
CH4 + O2→CO2 + 2H2O
Now look at the O atoms. They are not balanced. There are 2 O atoms on the left side and 4 on the right. Place a coefficient of 2 in front of the O2. We now have 4 O atoms on both sides.
CH4 + 2O2→CO2 + 2H2O
The equation is now balanced. Each side has 1 C atom, 4 H atoms, and 4 O atoms.
Answer:
molarity = 3.0625 M
Explanation:
Molarity can be calculated using the following rule:
molarity = number of moles of solute / volume of solution
We are given that:
number of moles of solute = 9.8 moles
volume of solution = 3.2 liters
Substitute with the givens in the above equation to get the molarity as follows:
molarity = 9.8 / 3.2
molarity = 3.0625 M
