Q$.$What is meant when Said enthalpy is a function of temperature Only

Q$.$ What is meant by specific entropy of a mixture?$($ per mole$)$

Q$.$ How can an intensive property which is mass independent be used to define mass transfer equilibrium between $2$ species $($ chemical species $)$is theser mass exchange in chemical reactions? How $,$ when? Is there an exchange even in Combustion reactions?

Q$.$ Is chemical potential a intensive or extensive property?

Q$.$ Intensive or extensive properties of the mixture as the sum over the indivual components evaluated at the mixture temperature and their own partial pressure

What is this statement about $,$ what is it trying to saying $($ about mixtures$)$ plz explain as easy as possible

Q $.$ What is molar enthalpy of a chemical species $?$ Is there a difference between Entropy of mixture and Entropy of mixing
