Chemical, if it gives off a reaction like that its chemical
By adding catalyst e.g. mno2,vanadium oxide
by increasing the temperature if it is an exothermic reaction
by also decreasing if it is an endothermic reaction
Answer:
Line A
Explanation:
In consideration of Charles's law of gases, temperature is directly proportional to pressure of the gas.
(3) Cl2(g) <==> Cl2(l), because it has an equilibrium between the two phases of liquid and gas.
Answer:
The new volume is 2.75L
Explanation:
This is another case of Charles Gay Lussac law, where the volume varies directly proportional to T°, if the pressure keeps on constant.
V₁ / T₁ = V₂ / T₂
25°C + 273 = 298K
55°C + 273 = 328K
2.5L / 298K = V₂ / 328K
(2.5L / 298K) . 328K = V₂
2.75L = V₂
