Answer:
The hydrogen peroxide decomposes as:
Explanation:
Hydrogen peroxide antiseptic although tightly capped but left on the shelf for a long time leads to swollen bottle and opens with a hissing sound because hydrogen peroxide reacts with air in presence of light to dissociate into water and oxygen molecules that leads to high volume of content in the tightly closed bottle and formation of water molecules from hydrogen peroxide.
Once the hydrogen peroxide has turned into water molecules it is no longer effective as an antiseptic.

Answer:
mass flow rate = 11.464 kg/sec
Explanation:
given data
P = 200 kPa = 2 × Pa
temperature = 150°C = 423 k
volumetric flow rate = 7000 liters/s
solution
first we get here molar flow rate that is express as
molar flow rate = .................1
put here value
molar flow rate =
molar flow rate = 398.06 mol/sec
and
now we get mass flow rate
mass flow rate = molar flow rate × average mol weight ..............2
mass flow rate = 398.06 × 28.8
mass flow rate = 11464.3 g/sec
mass flow rate = 11.464 kg/sec
