The 2 represents that it is a double carbon bond
it looks like..
C-C = C-C
Answer:
1.4200 g
Explanation:
The chlorine gas has a molecular formula Cl2. In table periodic, the molar mass of one atom of chlorine is 35.5 g/mol, so the molar mass of Cl2 is 71 g/mol.
Molar mass, mass and number of moles are related by the equation below:

Where n is the number of moles, m is the mass, and MM is the molar mass of the compound.
So, for 0.0200 moles of Cl2 produced:

m = 71x0.0200
m = 1.4200
The answer for The question is (D)The density changed
Im pretty sure its D. I would wait for others though.
The aspects not accounted for in the ideal gas law are the force of attraction of the gas molecules on each other and the volume of the gas molecules.
- In the ideal gas law, it it assumed that the molecules of the gas are so far away from each other and thus they do not exert a significant force of attraction on each other.
- Also, the volume of each molecule of gas is <u>neglected</u> and assumed negligible and thus does not account for the <u>overall volume of the gas.</u>

So, the aspects not accounted for in the ideal gas law are the force of attraction of the gas molecules on each other and the volume of the gas molecules.
