Why does the oxidation of organic compounds by molecular oxygen to produce co₂ and water release free energy?
a) the covalent bonds in organic molecules and molecular oxygen have more kinetic energy than the covalent bonds in water and carbon dioxide.
b) electrons are being moved from atoms that have a lower affinity for electrons (such as
c) to atoms with a higher affinity for electrons (such as o).
c) the oxidation of organic compounds can be used to make atp.
d) the electrons have a higher potential energy when associated with water and co₂ than they do in organic compounds.
e) the covalent bond in o₂ is unstable and easily broken by electrons from organic molecules.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
