Answer:
Standard cell potential is 0.56V
Explanation:
Standard reduction potential (
) are given below-
As 
is greater than 
therefore Fe will be oxidized to 
and 
will be reduced to Cu
Oxidation: 
Reduction: 
------------------------------------------------------------------------------------------------------
Overall: 
Standard cell potential, 
Answer:
Chemical reaction A, because the reactant is a compound
Explanation:
In a decomposition reaction, a compound is broken down into its components, so the number of products is greater than the number of reactants
Answer:
2,3 -Dimethyl pentane
Explanation:
The given molecule is 2,3-Dimethyl pentane.
First of all select the longest chain of C-C atom. This will be the parent name.
In given structure the longest chain is straight chain that contain five carbon. Thus the parent name will pentane and there is no double or triple bond the given structure is of alkane.
Than locate the positions of functional groups attached.
In given structure there are two methyl groups are present. Give the name in such a way that functional groups will have lowest number. In given case we will start from the left.
The first methyl group will have number 2 and second will have number 3.
The name will be,
2,3-Dimethyl pentane
The potential energy stored in the form of heat is called as enthalpy of a system. The reactions in which a system absorbs heat, are called as endothermic reactions. The ones in which a system releases heat, are called as exothermic reactions
