According to
Graham's Law of Diffusion,"the rates of diffusion of two gases are inversely proportional to the square root of their Molar masses or Densities at the same pressure and temperature".
r₁ / r₂ =
Where,
r₁ = Rate of Fluorine
r₂ = Rate of Bromine
M₂ = Molar mass of Bromine = 159.8 g/mol
M₁ = Molar mass of Fluorine = 37.98 g/mol
Putting values,
r₁ / r₂ =
r₁ / r₂ =
r₁ / r₂ =
2.04Result: Fluorine effuses
2 times faster than Bromine gas.
A producer gets it's matter from it's surroundings. E.g a plant will get minerals and water from the ground through it's roots for photosynthesis.
Plants can also produce food by using the sun's light for photolysis of the water molecules. (Basically splitting the H20 into Hydrogen and O2 (oxygen gas). They release oxygen back into the air and combine the Hydrogen ion with carbon dioxide that they obtained from the air to create sugar (glucose) which is basically chemical food for the plants. This is the summed up process of photosynthesis.
Answer:
Mars
Explanation:
It's the furthest away from the sun so it has the longest orbit
It is an open system.<span>
- Closed
system </span>is a physical system which allows to exchange energy <span>with
the </span>surrounding but not allows to exchange matter. <span>
- Isolated system </span>does not exchange either matter or energy with the external
environment.<span>
- Open system </span>is a type of physical system which allows to exchange both matter <span>and </span>energy with the surroundings.<span>
<span>Hence, Alex's
experimental setup which has an unsealed beaker is an open system.</span></span>
