Answer:
23.2L
Explanation:
The following were obtained from the question:
V1 = 22.5L
P1 = 748 mmHg
P2 = 725mmHg
V2 =?
The new volume can be obtained by doing the following:
P1V1 = P2V2
22.5 x 748 = 725 x V2
Divide both side by 725
V2 = (22.4 x 748) /725
V2 = 23.2L
The new volume is 23.2L

Acceleration = final velocity - initial velocity/time
Answer:
Coefficient's are 2, 2, 1
Explanation:
We are given;
Unbalanced equation;
H₂O₂ → H₂O + O₂
We are required to determine the suitable coefficients that would balance the equation.
- We need to know that for an equation to obey the law of conservation of mass it has to be balanced.
- Balancing involves making sure that the number of atoms of each element are equal on both sides of the equation.
In this case;
To balance the equation we put the coefficients 2, 2, 1 respectively
Therefore;
The balanced equation is;
2H₂O₂ → 2H₂O + O₂
Thus, Suitable coefficients are, 2, 2, 1
