Chemistry
1 answer:
Elena L [17]3 years ago
6 0

Answer:  The oxidation number of chlorine in Cl_2 is zero

Explanation:

Oxidation number or oxidation state : It represent the number of electrons lost or gained by the atoms of an element in a compound.

Rules for Oxidation Numbers are :

1.  The oxidation number of a free element is always zero.

2. The oxidation number of a monatomic ion equals the charge of the ion.

3. The oxidation number of  oxygen (O)  in compounds is usually -2.

4. The oxidation number of a Group 17 element in a binary compound is -1.

5. The oxidation number of  Hydrogen (H)  is +1, but it is -1 in when combined with less electronegative elements.

6. The sum of the oxidation numbers of all of the atoms in a neutral compound is zero.

7. The sum of the oxidation numbers in a polyatomic ion is equal to the charge of the ion.

As Cl_2 exists as a free molecule, its oxidation state is zero.

A student is reading the volume from a standard 50-mL buret identical to what you used in the lab. The bottom of the meniscus is
Nutka1998 [239]

Answer:

20 mL

Explanation:

<em>The student should record 20 mL as the correct volume.</em>

The curved surface of a liquid that is usually observed in a buret is referred to as the meniscus. This meniscus is created as a result of the surface tension of the liquid against the walls of the buret. <u>Hence, in order to avoid errors due to parallax, the bottom of the meniscus should be read and not the top.</u>

Therefore, the correct volume that the student should record is 20 mL.
