At the energy-generating station, the coal is burned. Burning changes, the coal's chemical energy into sound energy.
true or
false

The correct answer is - false.

Explanation:

At the energy-generating station, when the coal is burned, the chemical energy store in the coal converted into thermal energy and light or luminous energy.

The thermic energy generated used to heat and boil the water or liquid to generate the gas and generate the kinetic energy to move the fan that is desgined to generate the electrical energy.

Thus, the statment is false statement as it does not convert into sound energy.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
