Answer:
E i is like Math so I think this will help you
We are going to use Henry's law:
when C1/P1 = C2/P2
at a constant temperature.
and when the C1 and C2 are the concentration of the gases ( the solubility)
and P1 and P2 is the Pressure 1 and pressure 2
and when 760 mmHg = 1 atm
so, by substitution:
1.6 g/L / 1 atm = C2 /2.5 atm
∴C2 = 1.6g/L *2.5atm /1 atm
= 4 g/L
What is the following ??? Do you have any more information
Answer:
Wheel and axles
Explanation:
Clocks run on a complex system of gear trains. This provides the energy to turn the hands of the clock. A high-ratio gear train gears the weight drum way up so that you don't have to rewind the clock very often. This somehow disengages, slips or ratchets the gear train so the clock can be rewound and set.
Energy goes into the system, hitting some of the molecules and making them lighter than the surrounding air. this causes them rise being less dense.
