Answer:
The key difference between empirical and molecular formulas is that an empirical formula only gives the simplest ratio of atom whereas a molecular formula gives the exact number of each atom in a molecule.
B) It was transformed into 350 J of heat energy.
Explanation:
The remaining 350J of energy must have been transformed into 350J of heat energy.
A fan works by converting electrical energy into heat energy.
- According to the third law of thermodynamics "no system is 100% efficient". The conversion of the energy from one form to another involves a lost in energy.
- Heat is one very familiar way by which energy can be lost.
- Some component energy is used to heat the fan in the process and it is a wasted energy.
- Friction surfaces a heat energy in this process.
