The energy called Activation Energy (Ea) is required in all chemical cells during a chemical reaction. Sorry if I am wrong.
Answer:
This is an example of (substitution nucleophilic bimolecular) reaction
Explanation:
Conversion of t-butyl alcohol to t-butyl bromide proceeds through (substitution nucleophilic bimolecular)mechanism.
In the first step, -OH group in t-butyl alcohol gets protonated.
In the second step, stable tertiary carbocation (t-butyl cation) is produced by removal of .
In the third step, bromide ion attacks to t-butyl cation and produces t-butyl bromide.
Removal of from n-butyl alcohol will produce an unstable primary carbocation (n-butyl cation). Hence, to produce this unstable carboction, large amount of activation energy is required. Therefore, n-butyl alcohol gives much slower reaction with HBr.
Reaction mechanism has been shown below.
The density would be the same for the whole bar as well as one half of the bar. Density is a identity I believe, by this I mean that it stays the same no matter how little or how much of the same substance you have. Since density = mass / volume, half the bar has half of the weight as well as half of the volume of the whole bar, making the density the same.
For example, a block weighs 10 grams and has a volume of 5 ml. the density would be d = 10/5 or, d = 2g/ml
Half of the block weighs 5 grams and has a volume of 2.5 ml. The density is d = 5/2.5, or, d = 2 g/ml.
See, although there are different amounts of the same substance, their density is the same.
