Mass % of nitrogen = mass of nitrogen*100 / total mass
= 14*100 / (1+ 14 + 32)
= 14*100 / 47
= 29.7 %
Answer:
Explanation:
Hello,
The six-carbon benzene ring contains two types of bonds: C-C and C-H bonds, that are -hybridized σ bonds, and the six π bonds that form the aromatic ring. The σ bonds form from one 
orbital and two 
orbitals from each carbon, which then bond the carbon to the two carbons on either side and the carbon's single hydrogen. The remaining orbital from each carbon atom sticks out above and below the plane of the ring; these orbitals overlap sideways, rather than lengthwise, to form the aromatic π bond system.
Best regards.

I think the answers D. Hope this helps you.
Explanation:
Answer:
In Haloarenes the C atom to which the X group is attached is SP2 hybridized thus it is become difficult to replace it by the Nucleophile. Since arenes and Vinyl halides are electron rich molecules due to presenceof n bonds, they repel Nucleophile attacking them.
Answer:
Water splitting is the chemical reaction in which water is broken down into oxygen and hydrogen: 2 H2O → 2 H2 + O. Efficient and economical photochemical water splitting would be a technological breakthrough that could underpin a hydrogen economy.
Explanation: 2 H2O → 2 H2 + O.
