Answer:

Because their unfilled d-orbital becomes excited

Explanation:

Transition metals are a group of elements that has an incompletely filled d shell e.g chromium, nickel, copper, iron etc. This characteristics of transition elements confers upon them the ability to form colored ions or compounds.

Transition elements/metals form colored compounds when the partially complete d-orbital becomes excited as a result of absorption of visible light. d-orbital at its lower energy becomes excited to d-orbital at a higher energy.

When might a plot of ln[a] vs time not yield a straight line?

podryga [215]

Considering a reaction:
A → B
The rate equation may be described as:
r = -k[A]ⁿ
Taking the natural log,
ln(r) = -nln([A]) + ln(k)
Therefore, the only time the graph of ln[A] vs time will be a straight line is when the order of the reaction is 0, meaning the reaction is independent of reactant concentration.

Describe the structure of ammonium lauryl sulfate. Refer to the given diagram. Your answer should include the type of bonding, t

Anit [1.1K]

Answer:

The compound contains lauryl sulfate and ammoium ions. Lauryl sulfate contains lauric acid (in black and white) , the fatty acid formed by the covalent bonds between C-C attached to hydrogens, and sulfate ions attached to lauric acid (in red) with C-S covalent bond. Sulfer is attached to oxygen by covalent bonds. In Ammonium ions, N is surrounded by four hydrogen atoms.
