Explanation:
Answer:A. Dilute copper and ascorbic acid solutions should be disposed of in the waste container in the hood.
C. Metal and graphite electrodes should be rinsed with water, dried, and returned to their positions on the lab bench.
D. The contents of the half-cell module should be disposed of in the waste container in the hood.
Explanation: An electrochemical cell is a cell that has the capability of producing Electric energy from chemical reaction (voltaic cells) or using Electric energy to make chemical reactions to take place(electrolytic cell). For a proper or effective waste disposal in an electrochemical cell the following options are correct.
Dilute copper and ascorbic acid solutions should be disposed of in the waste container in the hood.
Metal and graphite electrodes should be rinsed with water, dried, and returned to their positions on the lab bench.
The contents of the half-cell module should be disposed of in the waste container in the hood.
Answer:
15.75g
Explanation:
Rearrange the formula: density = mass/volume, so that mass is the subject: mass = density × volume
Now substitute (plug in) the known values into the formula:
mass = 10.5 × 1.5 ⇒ mass = 15.75g
The mass of the silver necklace is 15.75g
Hope this helps!
