Answer:
d) Ni < Co < Fe < Zn < Al
Explanation:
electronegativity of Aluminium 1.6
electronegativity of Zinc 1.7
electronegativity of iron 1. 83
electronegativity of Cobalt 1.88
electronegativity of Nickel 1.91
As the electronegativity of aluminium is lower as compared to other, so it will have high tendency to easily lose electron and that is why Aluminium is more reactive than the other mentioned
Answer:
Explanation:
In a reaction, where, one of the reactant produces a colored product, visible spectroscopy can be used to determined the order of a reaction, the change in concentration of the reactant which forms the colored product is determined by absorbance measurement over time. The data for the concentration and time are plotted on the y and x axis and If we get a straight line it is a zero-order reaction. If instead, a plot of ln[concentration] versus time gives a straight line, it is a first order reaction. However, If 1/concentration versus time gives a straight line, it is a second order reaction kinetics. The other reactants may be changed while keeping this reactant as constant and change on rate of the reaction is observed to see If the other reactant affects the reaction or not.
The answer is calcium chloride.

Answer : The correct option is D.
Explanation :
Balanced chemical equation : It is defined as the mass or component of each atom should be equal on both sides of the equation.
The balanced chemical equation for the reaction of
and
is,

So, the correct option is D.
