Question 10: a) The solution with the lowest concentration of hydrogen ion ( $[H^+]$ ) will have the highest pH. Solution P has a pH of 13, which is the highest pH among the given solutions. Reason: pH is inversely related to the concentration of hydrogen ions. A higher pH indicates a lower $[H^+]$ .

b) An anti-acid is used to neutralize excess stomach acid, so it should be an alkaline (basic) solution. Solution P (pH 13) is strongly alkaline. Reason: It is a strong base that can effectively neutralize the acid in the stomach.

Question 11: a) P has atomic number 6, so its electronic configuration is $2:4$ . It is Carbon. S has atomic number 17, so its electronic configuration is $2:8:7$ . It is Chlorine. Carbon (P) needs 4 electrons to achieve a stable octet. Chlorine (S) needs 1 electron. They will form a covalent compound, Carbon tetrachloride ( $\text{CCl}_4$ ), where Carbon shares its 4 valence electrons with 4 Chlorine atoms.

\begin{array}{c} Cl \\ : \\ Cl \cdot \underset{\times}{\overset{\times}{C}} \cdot Cl \\ : \\ Cl \end{array}

(This is a simplified representation. A full dot-and-cross diagram would show all valence electrons for each atom, with 8 electrons around each atom.)
