Answer: $CaCl+LiCO_3\rightarrow CaCO_3+LiCl$

Explanation: A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

In the given reaction:

The molecular formula of Lithium carbonate is incorrect as lithium forms a monovalent cation but carbonate is a divalent polyatomic ion. Thus in order to form a neutral ionic compound two atoms of $Li^+$ must combine with one $CO_3^{2-}$ to give $Li(CO_3)_2$

Which of the following observations would indicate that a material is a pure substance?

Ira Lisetskai [31]

<span>The answer to the question is the option C. it cannot be physically broken down into different types of atoms. This means that the material is an element, which is a pure substance. Because an element is a pure substance that is formed by one only type of atoms. For example, gold is an element and all its atoms are of the same type. That is also true for any of the 118 elements of the periodic table. Compounds (other kind of pure substances) can be broken down into molecules (which contain different kind of atoms, but always in the same proportion) and mixtures (non pure substances) have different kind of substances.</span>
