From the Graham's law of effusion;
R1/R2 = √MM2/√MM1
Molar mass of chlorine gas is 71
Therefore;
1.87= √ 71 /√mm1
= 1.87² = 71/mm1 
mm1 = 71/1.87²
         = 71/3.4969
         = 20.3
Thus, the molar mass of the other gas is 20.3 , and i think the gas is neon

Lapatulllka [165]

Answer:

Please find the complete question in the attached file.

Explanation:

It would only be radioactive if the DNA molecule that employed the poly-T rand as templates. Its other molecule of the daughter would not have been radioactive as it did not need dATP for its replication. While each strand of the second molecule includes t, simultaneous reproduction dATP from both daughter molecules is needed so that each of those is radioactive.

Benzene is an organic chemical compound with the molecular formula C6H6. In the benzene molecule, carbon atoms form a ring with
Sergeu [11.5K]

Answer:

sp^2

Explanation:

Hello,

The six-carbon benzene ring contains two types of bonds: C-C and C-H bonds, that are  sp^2-hybridized σ bonds, and the six π bonds that form the aromatic ring. The σ bonds form from one s orbital and two p orbitals from each carbon, which then bond the carbon to the two carbons on either side and the carbon's single hydrogen. The remaining p orbital from each carbon atom sticks out above and below the plane of the ring; these p orbitals overlap sideways, rather than lengthwise, to form the aromatic π bond system.

Best regards.
