4. What is the major organic product of the following reaction sequence? $(CH_2)_3COOH$ 1) $SOCl_2$ 2) $AlCl_3$ ? (A) (B) OH (C) O (D) Cl O (E) COOH
In a different experiment, a student places a piece of pure Ba(s) in a beaker containing 250.mL of 6.44MHCl(aq) and observes that the rate of appearance of H2(g) bubbles when Ba(s) was added is much faster than the rate of appearance of bubbles when the Mg(s) was added. The student claims that the greater reactivity is due to the difference in ionization energy between Mg and Ba. Explain the difference in ionization energy between Mg and Ba in terms of atomic structure

4.1. Let A = \{3, 6, 9, 12\} and B = \{2, 4, 6, 8, 10, 12\}. Find each of the following sets. (a) $A \cup B$. (b) $A \cap B$. (c) $A \setminus B$. (d) $B \setminus A$.
Are the vectors \(\vec{u} = \begin{bmatrix} 0 & -2 & 5 \end{bmatrix}\), \(\vec{v} = \begin{bmatrix} 3 & -5 & -1 \end{bmatrix}\) and \(\vec{w} = \begin{bmatrix} 6 & -14 & 8 \end{bmatrix}\) linearly independent? linearly independent If they are linearly dependent, find scalars that are not all zero such that the equation below is true. If they are linearly independent, find the only scalars that will make the equation below true. \(\boxed{} \vec{u} + \boxed{} \vec{v} + \boxed{} \vec{w} = \vec{0}.\)
