(a)
Interpretation:
The number of days required to gold plate an earring on one side with applying given amount of current has to be calculated.
Concept Introduction:
An
Anode: The electrode where the oxidation occurs is called as an anode. It is a negatively charged electrode.
Cathode: The electrode where reduction occurs is called as a cathode. It is a positively charged electrode.
Redox reaction: Redox reaction is a type of
Generally, the anode compartment with oxidation components are written on the left side of the salt bridge and the cathode compartment with reduction components are notified on the right of the salt bridge. The cathode and anode are separated by using the double vertical line which actually represents the salt bridge. The species of different phases are notified by using a single vertical line in the cell notation.
(b)
Interpretation:
The number of days required to gold plate an earring on both sides has to be calculated.
Concept Introduction:
An electrochemical cell is a device in which a redox reaction is used to convert chemical energy into electrical energy. Such device is also known as the galvanic or voltaic cell.
Anode: The electrode where the oxidation occurs is called as an anode. It is a negatively charged electrode.
Cathode: The electrode where reduction occurs is called as a cathode. It is a positively charged electrode.
Redox reaction: Redox reaction is a type of chemical reaction, where both the oxidation and reduction occur at the same time. In a redox reaction, one of the reactant is oxidized and the other is reduced simultaneously.
Generally, the anode compartment with oxidation components are written on the left side of the salt bridge and the cathode compartment with reduction components are notified on the right of the salt bridge. The cathode and anode are separated by using the double vertical line which actually represents the salt bridge. The species of different phases are notified by using a single vertical line in the cell notation.
(c)
Interpretation:
The total cost of gold plating the given mass of material has to be estimated.

- A student proposes the following two-step synthesis of an ether from an alcohol A: 1. strong base A 2. R Is the student's proposed synthesis likely to work? If you said the proposed synthesis would work, enter the chemical formula or common abbreviation for an appropriate strong base to use in Step 1: If you said the synthesis would work, draw the structure of an alcohol A, and the structure of the additional reagent R needed in Step 2, in the drawing area below. If there's more than one reasonable choice for a good reaction yield, you can draw any of them. ☐ Click and drag to start drawing a structure.

Be sure to use wedge and dash bonds when necessary, for example to distinguish between different major products. ☐ ☐ : ☐ + NaOH HO 2 Click and drag to start drawing a structure.arrow_forwardShown below are five NMR spectra for five different C6H10O2 compounds. For each spectrum, draw the structure of the compound, and assign the spectrum by labeling H's in your structure (or in a second drawing of the structure) with the chemical shifts of the corresponding signals (which can be estimated to nearest 0.1 ppm). IR information is also provided. As a reminder, a peak near 1700 cm-1 is consistent with the presence of a carbonyl (C=O), and a peak near 3300 cm-1 is consistent with the presence of an O–H. Extra information: For C6H10O2 , there must be either 2 double bonds, or 1 triple bond, or two rings to account for the unsaturation. There is no two rings for this problem. A strong band was observed in the IR at 1717 cm-1arrow_forward
