What else is produced during the replacement reaction of magnesium and hydrochloric acid? Mg 2HCl → H2.
1 answer:
A reaction in which the chemical element of the reactant is replaced by another to produce a product is called a single replacement reaction.
In a reaction, a hydrogen, metal or halogen element can get replaced with other more reactive elements to yield products.
The reaction of magnesium and hydrochloric produces:
The reaction can be explained as:
- The reaction between the
and
is a single displacement reaction in which the more reactive metal replaces the less reactive metal from the compound.
- Magnesium metal is more reactive compared to hydrogen and hence replaces
from chlorine to produce:
Therefore, another product formed will be magnesium chloride.

There are one antibonding molecular orbitals present in molecular orbital model of c.
The cyclobutadiene has a pi system comprised of four individual atomic p - orbital and thus should have a four pi molecular orbitals. The compound is the prototypical antiaromatic hydrocarbon with 4 - electrons . Its rectangular structure is the result of jahn teller reaction which disorder the molecule and lowers its symmetry , converting the triplet to a singlet ground state. It is a small annulene . The delocalisation energy of the
electrons of the cyclobutene is predicted to be zero .

Answer:
Rate constant of the reaction is .
Explanation:
A + B + C → D + E
Let the balanced reaction be ;
aA + bB + cC → dD + eE
Expression of rate law of the reaction will be written as:
Rate(R) of the reaction in trail 1 ,when :
...[1]
Rate(R) of the reaction in trail 2 ,when :
...[2]
Rate(R) of the reaction in trail 3 ,when :
...[3]
Rate(R) of the reaction in trail 4 ,when :
...[4]
By [1] ÷ [2], we get value of c ;
c = 1
By [3] ÷ [4], we get value of b ;
b = 0
By [2] ÷ [3], we get value of a ;
a = 2
Rate law of reaction is :
Rate constant of the reaction = k
