The anode is zinc, and the cathode is the nail
Yes just like the take the elevator
It is true. The particles near the surface have enough kinetic energy to be able to escape away as gas.
Answer:
The methane gas burns
Explanation:
The burning of methane gas is a combustion reaction. Combustion is an exothermic process. For all exothermic processes, ∆H is negative.
Combustion reaction involves the evolution of heat. The energy of reactants is greater than the energy of products hence the excess energy is given off in the form of heat leading to a negative value of the enthalpy of reaction, hence the answer.
