Balancing of chemical equation is essential because of the law of conservation of mass, which states that the mass of a system can not be created or removed.
The second equation is balanced
This is because the number of elements of each atom in the product side equal the number of elements of each atom on the reactant side.
The first equation is not balanced
This is because there is 1 molecule of on reactant side as compared to 3 molecules of
To balance the equation we add a coefficient of 3 on sulphuric acid () and a coefficient of 3 on hydrogen (
)
Answer:
The new volume is 5.92 L, which is approximately 6 L
Explanation:
As the gas temperature increases, the molecules move faster and take less time to reach the walls of the container. This means that the number of crashes per unit of time will be greater. That is, there will be an increase (for an instant) in the pressure inside the container and the volume will increase.
So Charles's Law is one of the gas laws that relates the volume and temperature of a certain amount of gas at constant pressure and says that:
- If the temperature increases the volume increases
- If the temperature decreases the volume decreases
Mathematically this is expressed by:
When you want to study two different states, an initial and a final one of a gas, this law is expressed by:
In this case:
- V1: 8 L
- T1: 473 K
- V2: ?
- T2: 350 K
Replacing:
Solving:
V2=5.92 L
<u><em>The new volume is 5.92 L, which is approximately 6 L</em></u>
