Answer:
The gas occupy 2406.4 mL at 80 K.
Explanation:
Given data:
Initial volume of gas = 752 mL
Initial temperature = 25 K
Final temperature = 80 K
Final volume = ?
Solution:
The given problem is solved by using charle's law.
V₁/T₁ = V₂/T₂
V₂ = V₁. T₂ /T₁
V₂ = 752 mL × 80 k / 25 K
V₂ = 60160 mL. k/25 K
V₂ = 2406.4 mL
Answer:
Reflection involves a change in direction of waves when they bounce off a barrier; refraction of waves involves a change in the direction of waves as they pass from one medium to another; and diffraction involves a change in direction of waves as they pass through an opening or around a barrier in their path.

Concepts to understand before solving:
-Oxygen is ALWAYS reduced
-OIL- Oxidation Is Loss of electrons
-RIG- Reduction Is Gain of electrons
-the element that is oxidized is the reducing agent
-the element that is reduced is the oxidizing agent
A. 2H2 + O2 —> 2H2O
O is reduced, making it the oxidizing agent
H is oxidized, making it the reducing agent
B. 2KNO3 —> 2KNO2 + O2
O is reduced, making it the oxidizing agent
KNO is oxidized, making it the reducing agent
