HNO3 + S --> H2SO4 + NO Now identify the element oxidized and the element reduced. Which element is oxidized? Which element i

OleMash [197]

<u>Answer:</u> S is getting oxidized, N is getting reduced and O and H undergo no oxidation or reduction

<u>Explanation:</u>

The oxidation reaction is defined as the reaction in which a chemical species loses electrons in a chemical reaction. It occurs when oxidation number of a species increases.

A reduction reaction is defined as the reaction in which a chemical species gains electrons in a chemical reaction. It occurs when oxidation number of a species decreases.

For the given chemical reaction:

$HNO_3+S\rightarrow H_2SO_4+NO$

<u>On the reactant side:</u>

Oxidation number of H = +1

Oxidation number of N = +5

Oxidation number of O = -2

Oxidation number of S = 0

<u>On the product side:</u>

Oxidation number of H = +1

Oxidation number of N = +2

Oxidation number of O = -2

Oxidation number of S = +6

As the oxidation number of S is increasing from 0 to +6. Thus, it is getting oxidized. Similarly, the oxidation number of N is decreasing from +5 to +2. Thus, it is getting reduced.

The oxidation numbers of O and H remain the same on both sides of the reaction. Thus, they are neither getting oxidized or reduced.

Hence, S is getting oxidized, N is getting reduced and O and H undergo no oxidation or reduction

Which of the following elements matches the criteria below?

Tems11 [23]

Answer:

The answer to your question is below

Explanation:

1. Found in period 2. All the elements in the list are found in period 2.

a. F This option is correct

b. Be Beryllium is located in period two.

c. O also oxygen is found in period 2.

d. C Carbon is found in period 2.

2.- Can gain lose 4 electrons to become its nearest stable noble gas. Only Carbon.

a. F This option is wrong, F becomes stable when it gains 1 electron.

b. Be Beryllium becomes stable when it loses 2 electrons.

c. O Become stable when it gains 2 electrons.

<u>d. C </u><u>Become stable when it gains or loses 4 electrons.</u>

How did scientist discover that earths outer core is liquid

liberstina [14]

By studying seismic waves

Explanation:

Scientists discovered that the earth's outer core is liquid by simply studying seismic waves.

Seismic waves are elastic waves that have been used by geophysicists to study the earth's interior.

Interior of the earth is inaccessible due to high pressure and temperature conditions therein.
To study this part of the earth, an indirect method should be used.
Seismic waves produced during an earthquake due to their permeating nature have been used to study the interior.
Seismic P-waves can pass through any materials because they are longitudinal waves. They go through solids, liquids and gases.
S-waves can only pass through solids and not fluids.
On a seismograph, it was discovered that the S-waves were cut off in a part of the reading.
The waves re-appeared after a distance.
Since S-waves cannot pass through liquids, it has been hypothesized that the outer core is liquid.
