Answer:
The primary type of energy change which occurs by turning on the phone will be the conversion of the stored chemical energy of the battery into electrical energy. The chemical energy is also converted into light energy, sound energy and heat energy. With the passage of time, the energy will be changed back into the chemical energy when we will charge the phone again.
Answer:
The correct answer is - D C2H4.
Explanation:
Saturated hydrocarbons are hydrocarbons with single covalent C-C bonds. They are known as alkanes. The general formula for these hydrocarbons is CnH2n+2
Unsaturated hydrocarbons the hydrocarbons with double or triple covalent C-C bonds. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is CnH2n and CnHn-2
For the given options:
Option D: C2H4, is the simplest alkene with a double bond so it is an unsaturated hydrocarbon.
I believe that it most likely would be C,
