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!

forsale [732]

Answer: Amylose is a form of starch which has only α-1,4-links bonds glucose units.

Explanation:

Amylose is a polysaccharide made up of α(1-4) bound glucose molecules. The carbon atoms on glucose are numbered, starting at the aldehyde (C=O) carbon, so, in amylose, the 1-carbon on one glucose molecule is linked to the 4-carbon on the next glucose molecule.

How many lone pairs are around the central atom in the Lewis formula for the
barxatty [35]

Answer:

The answer to your question is None, sulfur share of its electrons

Explanation:

Just remember:

Sulfur, S, has 6 electrons in its outermost shell

Hydrogen, H, has 1 electron in its outermost shell

Oxygen, O, has 6 electrons in its outermost shell

See the picture below

The electrons of sulfur are in blue

The electrons of oxygen are in red

The electron in hydrogen is in yellow

Sulfur is the central atom and it shares all its electrons with the oxygen.

Jane described two substances which participate in photosynthesis.
Anika [276]

Answer: -

Substance A is carbon dioxide and Substance B is oxygen.

Explanation: -

Photosynthesis reaction involves the process of conversion of light energy of the sun into chemical energy by the green chlorophyll found in plants leaves.

The chemical equation for the process is

6 CO₂ +6 H₂O → C₆H₁₂O₆ + 6O₂

As we can see Carbon dioxide CO₂ reacts with water H₂O to form glucose. Oxygen is the gaseous product formed.

Thus Substance A is carbon dioxide and Substance B is oxygen.

Katena32 [7]

Answer:

TRUE                          

Explanation:

An Equipment grounding conductor are used to ground a non current-carrying metallic parts of any equipment. Its main function is to keep the equipment close to the ground potential as possible and is also allows a safer path for the ground-fault current to flow. If the equipment is grounded, all the excess current will go to the ground and will not damage the equipment.

Hence the answer is TRUE.
