Given below are two statements:
Statement (I): An element in the extreme left of the periodic table forms acidic oxides.
Statement (II): Acid is formed during the reaction between water and oxide of a reactive element present in the extreme right of the periodic table.
In the light of the above statements, choose the correct answer from the options given below:
Step 1: Statement (I) is incorrect because elements on the extreme left of the periodic table, such as alkali metals and alkaline earth metals, form basic oxides, not acidic oxides.
Step 2: Statement (II) is correct because non-metals, which are on the extreme right of the periodic table, form acidic oxides when they react with water.
For example, sulfur dioxide (\( \text{SO}_2 \)) reacts with water to form sulfurous acid (\( H_2SO_3 \)).
Thus, the correct answer is that Statement I is false but Statement II is true.
\[ f(x) = \left\{ \begin{array}{ll} 1 - 2x & \text{if } x < -1 \\ \frac{1}{3}(7 + 2|x|) & \text{if } -1 \leq x \leq 2 \\ \frac{11}{18} (x-4)(x-5) & \text{if } x > 2 \end{array} \right. \]
