Answer:
the answer is is putting ptessure on the gas
Explanation:
It's "C" a sample of dust particles at 0 Pascals
so one liter is about 2. something gallons so at 12.8 km/l you would get about 30 mpg which is insane but yeah
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

%yield = 88.5%
<h3>Further explanation</h3>
Given
Reaction
Cu(s) + 2 AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s)
Required
The percent yield
Solution
mol AgNO₃(MW=169,87 g/mol) :
= mass : MW
= 127 : 169.87
= 0.748
mol Ag from equation :
= 2/2 x mol AgNO₃
= 2/2 x 0.748
= 0.748
Mass Ag (theoretical) :
= mol x Ar Ag
= 0.748 x 108
= 80.784
% yield = (actual/theoretical) x 100%
%yield = 71.5/80.784 x 100%
<em>%yield = 88.5%</em>
