A decomposer is not a disturbance of the ecosystem because it decomposes dead animal bodies and recycles it into the soil which helps the food chain work
13 liters is the correct answer
13 liters is the final volume of the gas when the temperature and pressure remain constant.
v1/n1 = v2/n2
where,
v1 = initial volume = 8.5 liter
n1= initial mole of gas = 1.2 mole
n2= final mole of gas = 1.2+0.65= 1.85 mole
v2= final volume = ?
8.5 L/1.2 mol = v2/1.85 mol
7 L x 1.85 mol = v2/1.85 mol x 1.85 mol
13 L = v2
v2= 13 liter
<h3>What is a mole?</h3>
- A mole is an SI unit used to measure significant numbers of subatomic particles, such as atoms, molecules, or smaller particles.
- Any substance has an Avogadro number of molecules in a mole.
- The value of the Avogadro number is 6.02214076 ×
.
<h3>How much is a mole of gas?</h3>
22.4 L
At STP (Standard Temperature and Pressure = 0 °C, 1 atm), an ideal gas has a volume of 22.41 L/mol.
<h3>What makes something a mole?</h3>
- Chemists use the term "mole" because atoms, molecules, and other particles are all very small and require a large amount to even weigh them.
- A mole is a measurement of the number of particles present, not their mass.

Answer:
The answer to your question is Volume = 600 ml
Explanation:
Data
Volume 1 = 810 ml
Temperature 1 = 270°K
Pressure 1 = 1 atm
Volume 2 = ?
Pressure = 2 atm
Temperature 2 = 400°K
Process
1.- To solve this problem, use the Combine gas law.
P1V1 / T1 = P2V2 / T2
- Solve for V2
V2 = P1V1T2 / T1P2
2.- Substitution
V2 = (1)(810)(400) / (270)(2)
3.- Simplification
V2 = 324000 / 540
4.- Result
V2 = 600 ml
