Substitution reaction<span> monitors second-order kinetics; that is, the degree
of the reaction hinge on on
the concentration of two first-order reactants. In the circumstance of bimolecular nucleophilic </span>substitution, these two
reactants are the nucleophile and the haloalkane. So for this problem, the
answer is ch3br.
Vapor pressure is a criteria for a substance's volatility. This is the ability of a substance to transition from liquid to vapor. When the vapor pressure equals the external pressure, liquid turns to gas. Hence, if the substance has higher vapor pressure, then it is volatile. <em>Therefore, Sample A is more volatile than Sample B.</em>
Answer : The balanced molecular equation will be:
Explanation :
Molecular equation : It is a balanced chemical reaction in which the ionic compounds are expressed as the molecules instead of component ions.
According to the question, when iron react with copper (II) sulfate then it react to give iron (II) sulfate and copper as a product. In this reaction, iron is more reactive metal than the copper metal. So, it can easily displace copper metal form the solution.
The balanced molecular equation will be:
