Answer:
The structure for the compound elucidated (4-Ethylbenzoic acid) is attached below.
Explanation:
Degree of Unsaturation = 
(where n = no of moles)
= 
= 9 - 6+1 = 4
⇒ 2 ring. 3 double bonds.
From the 1H NMR data given (peaks labeled A-E)
A. 1.2 (3H, t) ⇒ -CH3
B. 2.6 (2H, q) ⇒ -C=C-H or Aromatic-CH3
C. 7.3 (2H, d) ⇒ Aro.-H
D. 8.0 (2H, d) ⇒ Aro.-H
E. 11.0 (1H, s) ⇒ -COOH
Answer:
heat and large amount of surface area
Explanation:
the heat and surface area allows the iron in the wool to combine with oxygen. by doing this it increases the mass of the steel wool
Mg+alcl3-->mgcl2+al is the
Answer:
A plasma.
Step-by-step explanation:
A <em>plasma i</em>s a hot, ionized gas in which the atoms have lost one or more of their electrons.
Thus, the plasma consists gaseous ions as well as the electrons that were stripped from them.
The Sun's high temperatures strip the electrons from its hydrogen and helium atoms, so the Sun is essentially a giant ball of plasma.
The first one is D hope it helps!
