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:
Synthesis reactions always yield one product. This is the most well-known example of a synthesis reaction—the formation of water via the combustion of hydrogen gas and oxygen gas.
Explanation:
Answer:
0.0222 mol KCl
Explanation:
2 KClO3 (s) 2 KCl (s) + 3 O2 (g)
2.73 g x mol
x g KCl = 2.73 g KClO3 x[ (1 mol KClO3)/ (122.5 g KClO3) ] x [(2 mol KCl)/ (2 mol KClO3)]
x g KCl = 0.0222 mol KCl
Thus, one atom of carbon will combine with two atoms of oxygen to form the molecule CO 2 ( carbon dioxide ). (b) From the chemical formula of the compound aluminium oxide Al 2 O 3 , the valency of aluminium can be determined. ... Hence the valency of aluminium is 3
