23.5cm^3
Explanation:
From the question given, we obtained the following data:
V1 = 25 cm^3
T1 = 25°C = 25 + 273 = 298K
P1 = 103.86 kPa = 103860Pa
V2 =?
T2 = at stp = 273K
P2 = at stp = 101325Pa
Using the general gas equation to solve for the new volume we obtain:
P1V1/T1 = P2V2/T2
(103860x25)/298 = 101325xV2 /273
298x101325xV2 = 103860x25x273
Divide both side by 298x101325
V2 = (103860x25x273) /(298x101325)
V2 = 23.5cm^3
it will form an a compund
Explanation:
Potassium chlorate on strong heating decomposes to the chloride and oxygen gas. The decomposition is faster in the presence of MnO2 as catalyst (Standard method of preparation of oxygen in the laboratory).
