Density = Mass ÷ Volume. You get 2.466
<h3>
Answer:</h3>
Chlorine gas (Cl₂)
<h3>
Explanation:</h3>
- According to the Graham's law of diffusion, the diffusion rate of a gas is inversely proportional to the square root of its density or molar mass.
- Therefore, a lighter gas will diffuse faster at a given temperature compared to a heavy gas.
- Consequently, the heavier a gas is then the denser it is and the slower it diffuses at a given temperature and vice versa.
In this case we are given gases, CI₂
, H₂,He and Ne.
- We are required to identify the gas that will diffuse at the slowest rate.
- In other words we are required to determine the heaviest gas.
Looking at the molar mass of the gases given;
Cl₂- 70.91 g/mol
H₂- 2.02 g/mol
He - 4.00 g/mol
Ne- 20.18 g/mol
Therefore, chlorine gas is the heaviest and thus will diffuse at the slowest rate among the choices given.
1 grams F2 to mol = 0.02632 mol
10 grams F2 to mol = 0.26318 mol
20 grams F2 to mol = 0.52636 mol
30 grams F2 to mol = 0.78954 mol
40 grams F2 to mol = 1.05272 mol
50 grams F2 to mol = 1.3159 mol
100 grams F2 to mol = 2.6318 mol
200 grams F2 to mol = 5.2636 mol
The amount of ethane decreases
increasing the temperature (adding energy), will drive the reaction to the left
<h3>What happens to the amount of ethane (C2H6) when the temperature of the system is increased ?</h3>
C2H4(g) <--> C2H6(g) + 137 kJ
because this reaction is an exothermic reaction and the heat is a product of this reaction, So when the number of temperature increases
- so (more heat will be added) so the reaction will go leftward (toward reactants ) so the amount of C2H4 & H2 will increase and the amount of ethane C2H6 will decrease.
