Answer:
The oxidation state of the reducing agent has changed from 0 to +2.
Explanation:
reducing agent is anything that loses electron or gains oxygen
in this case, zinc
Hey there !
Mole ratio :
<span>2 KMnO4 + 16 HCl → 2 KCl + 2 MnCl2 + 8 H2O + 5 Cl2
2 moles KMnO4 ----------------- 8 moles H2O
3.45 moles KMnO4 ------------- (moles H2O )
Moles H2O = 3.45 * 8 / 2
Moles H2O = 27.6 / 2
= 13.8 moles of H2O
</span>The option that was given is wrong , <span>You're right.</span>
Same number of valence electrons
Explanation:
Two elements posses similar chemical properties if they have the same number of valence electrons.
Chemical properties of any substance is determined by the number of valence electrons it possesses in its outer most shell.
Elements use their valence electrons to form chemical bonds with one another.
Elements with the same number of valence electrons will chemically combine the same way.
This is why elements in the same group on the periodic table have the same chemical properties.

Answer:
The mechanism is E1 and the product is cyclohexene
Explanation:
Attached to this answer is an image of the reaction mechanism of the reaction between cyclohexanol and concentrated sulfuric acid/phosphoric acid. The acid (H3O^+) acts as catalyst.
We can see that the first step in the mechanism is the protonation of the -OH group of the alcohol. This is followed by loss of water molecule which is a good leaving group.
The water now acts as a Lewis base by abstracting a proton from the substrate, forming cyclohexene and regenerating the acid catalyst.
