Explanation:
The seven holiest Hindu cities are said to be the sites of events recounted in mythological texts: Kashi (modern Varanasi, Uttar Pradesh), where the god Shiva founded a shrine of purification; Oudh (modern Ayodhya, Uttar Pradesh), birthplace of the god Rama; Mathura (in Uttar Pradesh), scene of Krishna's nativity; ...19 may. 2020
Well , I will say this is a false statement.
This is because compounds which were all made by the same bond have same physical properties but different chemical properties.
Chemical Properties :
How do the subtances react with ( water, acid,alkaline, base , gas like oxygen, etc. )
Physical Properties :
- Solubility of those subtances in (water or organic solvent )
- Electric Conductivity
- Melting or Boiling Point
- Density
- Smell (exp : Ammonia has pungent smell , Esters has fruity smell)
Answer:
The moles of KClO3 = 0.052 moles
Explanation:
Step 1: Calculate the pressure of oxygen gas
The oxygen has a total pressure (including water vapour) of 760 mmHg
The pressure of Oxygen = (760 - 26) mmHg
= 734 mmHg of water vapor
Step 2: Calculate the no of moles of oxygen
Using Ideal gas equation
P V = n R T
P = pressure of oxygen in N/m2 ( you should convert 734 mmHg to pascal or N/m2) = 97,858.6 N/m2 or pas
V = 2 litres = 0.002 m3
R = gas constant = 8.31
T= 27oC = 300 K
Applying this equation P V = n R T
97,858.6 x 0.002 = n x 8.31 x 300
n = 0.0785 mol of Oxygen
From the balanced equation
2 KClO 3 ---- 2 KCl + 3 O 2
3 moles of oxygen is produced from 2 moles KClO3
so 0.0785 mole of oxygen will be produced from x
x = (0.0785 x 2 ) / 3
x = 0.052 moles of KClO3
