Answer:
a. single replacement reaction
Explanation:
Mg(s) + 2HCl(aq)——-> H2(g) + MgCl2(aq)
Mg replaces H, so this is a single replacement reaction.
Answer:
The over all reaction :
The standard cell potential of the reaction is 0,.897 Volts.
Explanation:
Reduction at cathode :
..[1]

Reduction potential of
to 
Oxidation at anode:
.[2]

Reduction potential of
to 
To calculate the
of the reaction, we use the equation:

Putting values in above equation, we get:


The over all reaction : 2 × [1] + [2]
The standard cell potential of the reaction is 0,.897 Volts.
When hexan-1-ol is treated with conc. H₂SO₄ at moderate temperatures, Di-n-hexyl ether is formed via SN₂ mechanism.
SN₂ Mechanism is mechanism involving the factors of steric hindrance following the order of 1° > 2° > 3°. It is a Nucleophilic substitution reaction.
Williamson Ether Synthesis is the synthesis of ether through SN₂ mechanism in which an ether is treated with conc. H₂SO₄ at moderate temperature.
When hexan-1-ol is treated with conc. H₂SO₄ at moderate temperatures, Di-n-hexyl ether is formed as below:
CH₃CH₂CH₂CH₂CH₂CH₂OH +Conc. H₂SO₄-->(CH₃CH₂CH₂CH₂CH₂CH₂)₂0
Hexan-1-ol Di-n-hexyl ether
Williamson Ether Synthesis is a reaction involving a alcohol that is deprotonated to form an ether.

You should just try your best out what u think it will be okay ! I don’t know the answer I’m sorry
Answer:
107.8
Explanation:
64 gram of N2H4 produce 72 gram of H20
then by crossmultiplication
64*121.3/72=107.82
