Answer:
Fe
Explanation:
The cell potential is:
ΔE°cell = E°red(red) - E°red(oxid)
Where, E°red(red) is the reduction potential of the substance that is reducing, and E°red(oxid) is the reduction potential of the substance that is oxidizing. For the reaction be spontaneous and happen, ΔE°cell > 0.
The reduction takes place in the cathode, which is the negative pole, and the oxidation in the anode, which is the positive pole. So, the electrons flow from the positive pole to the negative pole (anode to cathode).
Then, if the voltmeter measured a negative potential, it means that is was attached incorrectly. So, the anode is Fe.
Complete Combustion of any hydrocarbon produces CO2 and H2O ( carbon dioxide and water).

As we all know that energy is the ability to do work
Answer:
temperature and number of molecules of gas
Explanation:
Boyle's law is one of the gas laws, which states that the volume of a gas is inversely proportional to the pressure at a constant temperature. The Boyle's law equation is given as follows:
P ∝ (1/V)
P = K/V
PV = K
Based on these, the temperature of an ideal gas and the number of molecules in the gas are kept constant in Boyle's law.
