(a)
Interpretation:
Which types of batteries are commonly recycled have to be found.
Concept introduction:
Primary battery: Primary batteries are irreversible transform chemical energy to electrical energy. When the initial supply of reactants is exhausted, energy cannot be readily restored to the battery by electrical means.
Secondary battery: This can be recharged, that is they can have their
(b)
Interpretation:
The
Concept introduction:
Electrochemical cell is a device capable of converting chemical energy into electrical energy or induces chemical energy by electrical energy. In the galvanic cell spontaneous redox reaction takes place. Redox reaction means the reaction in which the oxidation state of the atoms changes due to the occurrence of both reduction and its complementary oxidation reactions. The element under oxidation reaction loses electron whereas the element in the reduction gains electron.
Primary battery: Primary batteries are irreversible transform chemical energy to electrical energy. When the initial supply of reactants is exhausted, energy cannot be readily restored to the battery by electrical means.
Secondary battery: This can be recharged, that is they can have their chemical reaction reversed by supplying electrical energy to the cell restoring their original composition.
(c)
Interpretation:
Household battery recycling programs have not been as effective as those for recycling car batteries and list some reasons should be provided.

Chemistry In Context
- ercise 8.7 Penicillin, an important antibiotic (antibacterial agent), was discovered accidentally by the Scottish bacteriologist Alexander Fleming in 1928, although he was never able to isolate it as a pure compound. This and similar antibiotics have saved millions of lives that would otherwise have been lost to infections. Penicillin, like many of the molecules produced by living systems, is a large molecule containing many atoms. One type of penicillin, penicillin F, has the formula C14H20N2SO4 . Compute the mass percent of each element in this compound.arrow_forwardIf electrodes that are connected to a direct current (DC) source are dipped into a beaker of collodial iron(III) hydroxide, a precipitate collects at the negative electrode. Explain why this happens.arrow_forwardConsidering the fact that N2 makes up about 80% of the atmosphere, why dont animals use the abundant N2 instead of O2 for biological reactions?arrow_forward
- Formic acid, isolated in 1670, is the irritant in ant bites. The structure of formic acid is One of the carbonoxygen bonds has a length of 136 pm; the other is 123 pm long. What is the length of the CO bond in formic acid?arrow_forwardA common misconception is that the following chemical reaction occurs when water is boiled: 2H2O(l)2H2(g)+O2(g) instead of H2O(l)H2O(g) a What evidence do you have that the second reaction is correct? b How would the enthalpy of the wrong reaction compare with that of the correct reaction? c How could you calculate the enthalpy change for the wrong reaction (Chapter 6)?arrow_forwardYou are working in the office of a precious metals buyer. A miner brings you a nugget of metal that he claims is gold. You suspect that the metal is a form of fools gold, called marcasite, that is composed of iron and sulfur. In the back of your office, you have a chunk of pure gold. What simple experiments could you perform to determine whether the miners nugget is gold?arrow_forward

Assume that to make the numeral 3 on a given watch, a sample of paint containing8.0107 mole ofR88228a was used. This watch was then put in a drawer and forgotten. Many years later someone finds the watch and wishes to know when it was made. Analyzing the paint, this person finds1.0107 moles ofR88228a in the numeral 3. Flow much time elapsed between the making of the watch and the finding of the watch? Watches and clocks with radium dials.arrow_forward
