4 carbon atoms in a branched chain
2 methyl groups (-CH3) on carbon atom number 2 and carbon atom number 3
See attachment file below.
Hope it helped!
Answer:
L2 add a for NAL add a 2 then for the first NA2 put a 4 and then the second NA2 put a 2 and it should be good
Explanation:
Shii ion even know it’s A
[H₃O⁺] = 8.86 x 10³ M
<h3>Further explanation</h3>
The dissociation of water :
H₂O(l)⇒H⁺+OH⁻
Hydrogen ions H⁺ bond with H₂O to form H₃O⁺ ions(hydronium ion)
When acid(Hbr acid) is in the presence of water(dissociates), the H⁺ ions bond with water molecules to form hydronium, the reaction :
HBr(aq)+H₂O→H₃O+(aq)+Br−(aq
So Ionization of HBr :
[HBr]= 8.86 x 10³,
From equation ratio [H₃O⁺] : HBr = 1 : 1, so
Fluorine in its standard state is F2.
