The connection with mathematics lies in the algebraic solution of unknowns (electrochemical ions, the amount of substances is often encountered), and in addition, you should have good mathematical digital sensitivity (which can speed up your balancing speed and correct rate).

The connection with physics lies in electrochemistry (electrolytic cell, galvanic cell, ion movement, current direction, etc.). ), and the other is mainly the determination of specific heat capacity used for combustion calorific value.

This is not an obvious connection, and although physics and chemistry are tested together, the topics are separate, and it will not be a mixture of mathematics and physics. In addition, mathematics, physics, mathematics and physics are integrated, and chemistry is a bit far away.
