Answer:
The best definition is: "Buffer capacity is the amount of acid or base that can be added to a buffer without destroying its effectiveness"
Explanation:
A buffer is a solution that is somewhat resist to pH changes by reacting with acids and bases that may be added into the solution. It's capacity is the amounto of acid or base that can be added into solution without much change in pH.
So the best definition is: "Buffer capacity is the amount of acid or base that can be added to a buffer without destroying its effectiveness"
Answer:
A single compound reacts with itself.
Explanation:
Disproportionation is a chemical reaction,most times a redox reaction, in which a molecule is transformed into two or more dissimilar products. In a disproportionation reaction, the species are simultaneously oxidized and reduced to form at least two different products.
A typical example of a specie that disproportionate is the copper I ion as shown below;
2Cu^+(aq) ------> Cu(s) + Cu^2+(aq)
The two oxidation states of copper formed in the disproportionation are Cu(0) and copper (II).
They are both sources of power for objects that people use.
Answer:
CARBON MONOXIDE
Explanation:
Carbon monoxide is produced by incomplete combustion of hydrocarbon fuels. Poisoning by carbon monoxide is caused by operating improperly vented space heaters or furnaces in poorly ventilated buildings.
