Answer :
Mass of Oxygen is: 0.784gm
Potassium chlorate is KClO3 and the decomposition looks like this...
2KClO3 ==> 2KCl + 3O2
4.50 g KClO3 x 1 mole/122.55 g = 0.0367 moles
0.0367 moles KClO3 x 3 moles O2/2 moles KClO3 = 0.0245 moles O2 (see mole ratio in balanced equation)
mass of O2 = 0.0245 moles O2 x 32 g/mole = 0.784 g O2 formed
What is the pressure of a mixture of CO2 and KR?
A mixture of CO2 and Kr weighs 37.0 g and exerts a pressure of 0.737 atm in its container. is expensive, you wish to recover it from the mixture.
How much oxygen is created when one mole of potassium chlorate breaks down?
in the reaction 2K C lO3 2K C l + 3O2 K C lO3? This demonstrates that 3 moles of oxygen gas are created for every 2 moles of degraded potassium chlorate.
How is high pressure liquid CO2 produced?
High pressure liquid CO 2 is produced by compressing the gaseous CO 2 in multistage compressors to pressures in the neighbourhood of 69 bar (1000,76 psi) pressure, then cooling it to around 18 °C (64,4 °F). It is customarily filled into specially constructed steel cylinders.
