What is the oxidation state of an element that is not involved in bonding

Chemistry
1 answer:
masha68 [24]3 years ago
6 0

Answer:

Zero

Explanation:

The oxidation state of an element that is not involved in bonding is zero. An atom in its free and uncombined state has zero oxidation number.

The extent of oxidation of each atom of the elements in a molecular formula or formula unit or an ionic radical is given by the oxidation number.

  • The formal charge assigned to an atom present in a molecule or a formula unit or ion based on some arbitrary rules is given by the oxidation number.
  • Elements in their uncombined state or one whose atom combine with themselves to form molecules  have zero oxidation number.

A flask contains 0.83mol of neon gas at a temperature of 35°C. The pressure gauge indicates 0.37atm inside the flask. What is th
Angelina_Jolie [31]

Answer: 5.66 dm3

Explanation:

Given that:

Volume of neon gas = ?

Temperature T = 35°C

Convert Celsius to Kelvin

(35°C + 273 = 308K)

Pressure P = 0.37 atm

Number of moles N = 0.83 moles

Note that Molar gas constant R is a constant with a value of 0.0082 ATM dm3 K-1 mol-1

Then, apply ideal gas equation

pV = nRT

0.37atm x V = 0.83 moles x 0.0082 atm dm3 K-1 mol-1 x 308K

0.37 atm x V = 2.096 atm dm3

V = (2.096 atm dm3 / 0.37atm)

V = 5.66 dm3

Thus, the volume of the neon gas is 5.66 dm3

White raven [17]

Answer:

Here you go.

Explanation:

First of all, there are reactants and products…

Reactants are in the left side (in bold).

Products are on the right (without bold)

Example; NH3 + O2 → N2 + H2O

For each of the bonds listed, tell which atom is more negatively charged a. C--H b. C--N c. C--S d. C--O
blondinia [14]

Explanation:

The atom is considered to be more electronegative , when it has the tendency to get a slight negative i.e. , delta negative charge on it , and the other atom gets a delta positive charge .

In the periodic table ,

As we go left to right in the periodic table , the electronegativity increases ,

and

As we go top to bottom , the electronegativity decreases .

Hence , from the option given in the question ,

a. C--H , the electronegativity of both the atom is almost the same , but looking at the treads of the periodic table , Carbon is more electronegative than hydrogen .

b. C--N ,  the electronegativity of both the atom is almost the same , but looking at the treads of the periodic table , nitrogen is more electronegative than Carbon .

c. C--S , the electronegativity of both the atom is almost the same , but looking at the treads of the periodic table , sulfur is more electronegative than Carbon .

d. C--O , the electronegativity of both the atom is almost the same , but looking at the treads of the periodic table , oxygen is more electronegative than Carbon .
