Antimony cannot be broken down by chemical means because it is an element, a principle building block of matter. All other choices are compounds, which can be separated if put through enough stress to break the bonds between the atoms.
An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, or sodium chloride (NaCl), in water would be represented as Na+(aq) + Cl−(aq).
Photosynthesis. animal cells can't carry out photosynthesis since they don't have chloroplasts.
