1) Zn(s) + 2 HO2CCH3(l) --> Zn(O2CCH3)2 + H2(g)

There are two half reactions:
Zn -->Zn (2+) + 2e-
2e- + 2 H+ --> H2

(the acetic acid ionized to form H+ and acetate- ions)


2) It's a red-ox (reduction-oxidation) reaction. The Zn gives up 2 electrons to the 2 hydrogen atoms. In general one element loses electrons and another gains electrons. The element gaining the electrons is the oxidizer and the element losing them is the reducing agent. The oxidizer becomes reduced and the reducing agent becomes oxidized.

3) Hydrocarbons and oxygen.

Zn + 2HCl → ZnCl2 + H2 This reaction is rapid, because HCl is a strong acid and provides more reactive H+ ions. The products are zinc chloride and hydrogen gas. Zn + 2CH3COOH → Zn(CH3COO)2 + H2 This reaction is slower, because acetic acid is a weak acid. The products are zinc acetate and hydrogen gas.

So I would classify it as expeditious
Hope it helps!

Answer:

  • <em><u>Measurement of the amount of variation of the species in a given area. </u></em>

Explanation:

<em>Bio</em> preffix means life. Thus, literally, biodiversity means how diverse is the life. This is, how many different organisms an ecosystem or biome has.

Thus, biodiverstiy, although more complex than just that, is a measure of the number of species that live in a region.

The biome with most species than any other, this is the biome with the greatest biodiversity, is the tropical rainforest biome, which are located near the equator. As you can imagine, a large number of different plants, animals, and microorganisms live in these forests, making them the regions with greatest biodiversity on the planet.

iVinArrow [24]

Answer:

See explanation

Explanation:

The IUPAC name of aspirin is 2-Acetoxybenzoic acid. It is composed of an acetoxy moiety and a benzoic acid moiety.

The compound can be hydrolysed under prolonged storage conditions to yield acetic acid which causes the vinegar like odour.

Also, one of the products of this hydrolysis bears a phenol group which reacts with FeCl3 to give a purple color.
