Question
A metal automobile body rust in the atmosphere is known as uniform corrosion Half-life of a reaction particularly is meaningful for second order reaction Fuel cells, like a battery, cannot be refueled on an on going basis. Corrosion is a spontaneous reaction. When one or more atoms gains one or more electrons it is called oxidation. A secondary cell is one that does not require the cells be recharged. The effect o f ground level ozone accumulation are typically experienced in cold weather Ozone molecules are destroyed by chlorine atomsExplanation / Answer
a) true..because the whole body is open to the same atmosphere.
b) false...half life of a reaction is meaningful for first order reaction
c) false ...fuels can be refueled.
d) true ...corrosion is a apontaneous reaction , free energy released in tyhis process is negative.
e) false....loss of electrons is oxidation
f) false....secondary cell is a rechargeable electric cell that converts chemical energy into electrical energy by a reversible chemical reaction.
h) true...ozone atoms are destroyed by free chlorine atoms.
