Answer: The original volume in liters was 0.0707L
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 0.85 atm
= final pressure of gas = 456 mm Hg = 0.60 atm (760mmHg=1atm)
= initial volume of gas = ?
= final volume of gas = 94.0 ml
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
(1L=1000ml)
Thus the original volume in liters was 0.0707L
The time taken for the concentration of N2O to decrease to 32% of its initial concentration is calculated as follows
In(A1/A0)=-Kt
A1= final concentration = 32/100=0.32
A0= initial concentration =100/1000=1
K= constant= 0.76 per sec
time is therefore calculated as follows
In(0.32/1)= -0.76 t
-1.1394 =-0.76t divide both sid3es by -0.76
t is therefore= 1.5 s
Answer: Very small fragments of solid materials or liquid droplets suspended in air are called particulates. ... For example, solid particulates between roughly 1 and 100 μm in diameter are called dust particles, whereas airborne solids less than 1 μm in diameter are called fumes.
