zinc pennys are silver....
No, you cannot differentiate between brass and bronze solely based on sound. Brass is an alloy of copper and zinc, while bronze is an alloy of copper and tin. The compositions of the two alloys affect their physical properties, such as color and hardness.
Characteristics we use to tell the difference between kinds of matter are called _________ Properties?
Assuming you mean a US cent, in general if its date is 1981 or older, it is predominantly copper. The major exception would be 1943 cents that were made of zinc-plated steel due to wartime shortages. 1982 cents were struck in both zinc and bronze so you need to weigh them - a bronze cent weighs about 3.1 gm while a zinc one weighs 2.5 gm.
You have to know its date and in some cases its mint mark. Depending on the date, however, it's not always possible to tell unless you also weigh the coin on and accurate scale because the composition was changed in the middle of a year. In particular, there were multiple varieties of cents struck in 1864 and again in 1982. The link below lists all cents by date and mint mark, and the composition(s) of each one.
Yes, a person can tell the difference between hydrocodone and oxymorphone. While both are opioid medications with similar effects, they have different chemical structures and potencies. Oxymorphone is generally more potent than hydrocodone, so they may have different effects and side effects.

Have it checked by a coin dealer.
This goes for all pennies, the blank penny was created in Philedelphia and the penny with the D was created in Denver. If you want to know the material or type you should see "how do you tell the difference between 1982 pennies?"
All 1941 pennies are made of bronze which is mostly copper.

If it was minted in 1981 or before [except for 1943 which were made from steel] it is bronze. In 1982 some were made of bronze and some were made of copper clad zinc. The copper clad zinc cents are lighter than the bronze cents. You can weigh them to tell the difference. Also, if you drop them on a hard surface, the bronze cent will have a greater metallic ring to it than the zinc cent. Bronze cents look a little different in color too. While not a foolproof way to tell, most seem to have a slightly darker appearance than the zinc cents. This is because the plating on the zinc cents is pure copper and the bronze cents are not pure copper and thus have a slight difference in color usually.
