Answer:
A) 2-pentene
Explanation:
We count from side where we encounter double bond closest so that's going to be from left to the 2nd carbon. Total carbons are 5.
Thus pent- for prefix of 5 carbons and -ene as suffix for double bond.
2- for locant of double bond.
Thus, 2-pentene
The solution needed is prepared as below
by use of the M1V1 =M2 V2 formula where
M1 = 2.25 L
v2 = 1.0M
M2 = 9.0 M
V2 =? l
make V2 the subject of the formula V2 =M1V1/M2
= 2.25 L x 1.0M/9.0 M = 0. 25 L
therefore the solution need 0.25 L of 9.0M H3PO4 and dilute it a final volume of 2.25 l
It’s obvious that it’s 13 because 89 - 92 =13
The product of the reaction between lithium hydroxide and hydrofluoric acid is
lithium fluoride (LiF) and water(H₂O)
<u><em>Explanation</em></u>
Base react with acid to form salt and water.
Lithium hydroxide( <em> a base</em>) react with hydrofluoric acid (<em> an acid</em>) to produce lithium fluoride( <em> salt)</em> and water according to reaction below
