Answer:
Final volume after applying 880 mmHg pressure = 89.28
Explanation:
Initial volume (V 1)= 100 ml
Initial pressure (P1) =780 mm Hg = 780/780 = 1atm
Final pressure (P2)=880 mm Hg = 880/780 =1.12 atm
Final volume (V2)=?
We know that,
Applying Boyle's law,
P1 V1=P2 V2
1*100=1.12*V2
100=1.12*V2
100/1.12=V2
89.28=V2
V2=89.28 ml

Answer:
The mass of the neon gas m = 1.214 kg
Explanation:
Pressure = 3 atm = 304 k pa
Volume = 0.57 L = 0.00057 
Temperature = 75 °c = 348 K
Universal gas constant = 0.0821 
We have to change the unit of this constant. it may be written as
Universal gas constant = 8.314 
Gas constant for neon = 
= 0.41 
From ideal gas equation,
P V = m R T ------- (1)
We have all the variables except m. so we have to solve this equation for mass (m).
⇒ 304 × 
× 0.00057 = m × 0.41 × 348
⇒ 173.28 = 142.68 × m
⇒ m = 1.214 kg
This is the mass of the neon gas.
Run off
Explanation:
Run-off are the water sources that becomes polluted as they travel over the earth surface.
Surface run-off are water that moves on the earth surface. This water is a component of the water cycle which usually originate from precipitation.
- As the water moves through different terrain it comes into contact with different pollutants.
- Some of these run-off travels through mines, waste disposal sites among others.
- This leads to the contamination of this form of water as it moves through these earth materials.
- They are the most polluted water
