Answer:
Here's what I get
Explanation:
The reaction is an E1 elimination of an alcohol to form an alkene. It has three steps:
1. Protonation
The alcohol is protonated with aqueous sulfuric acid to convert it into a better leaving group.
2. Loss of the leaving group
A water molecule leaves in a unimolecular process to form a stable 3° carbocation.
3. Loss of an α-hydrogen
A water molecule removes an α-hydrogen, forming 2-methylpropene and regenerating the original hydronium ion.

Answer
Two different elements have similar chemical properties when they have the same number of valence electrons in their outermost energy level. ... Elements in the same column of the Periodic Table have the same number of valence electrons – that's why they have similar chemical properties.
Answer:
We colect 11.2 L of gas
Explanation:
Let's apply the Ideal Gases Law to solve this:
P . V = n . R .T
where P and T in STP are 1 atm and 273°K
The thing is n which means the number of moles for the gas.
As we know, 1 mol of anything has 6.02x10²³ particles so
6.02x10²³ are occupied in 1 mol of gas
3.00x10²³ are occupied in (3.00x10² .1) / NA = 0.500 moles
So let's go to the formula:
1 atm . V = 0.500m . 0.082 . 273K
V = (0.500m . 0.082 . 273K) / 1atm
V = 11.2L
There is a rule, which says that 1 mol of gas in STP, occupies 22.4L so, since we have half a mole, it will occupy half the volume
