Answer:

Percent yield = 17%

Explanation:

Given data:

Actual yield of lithium chloride = 6.0 g

Theoretical yield of lithium chloride = 35.4 g

Percent yield = ?

Solution:

Formula:

Percent yield = (actual yield / theoretical yield )× 100

Now we will put the values in formula.

Percent yield = (6.0 g/ 35.4 g)× 100

Percent yield = 0.17 × 100

Percent yield = 17%

What would be the charge on an ion whose neutral atom has an electron configuration of 2.8.7?
kompoz [17]

Answer:

–1

Explanation:

The electronic configuration of the neutral atom is given below:

2 8 7

From the electronic configuration of the neutral atom, we can see that the atom has 7 electrons in it's outermost shell. This implies that the element needs 1 more electron to complete it's octet configuration.

Therefore the charge on the ion of the element will be –1 indicating that the atom has received 1 electron to complete it's octet configuration.

SO42- 2NO2 H2OH2SO3 2NO3- In the above redox reaction, using oxidation numbers to identify the element oxidized, the element red
nignag [31]

Answer :  In the redox reaction,

Nitrogen element is oxidized and sulfur element is reduced.

NO_2 act as reducing agent and SO_4^{2-} act as an oxidizing agent.

Explanation :

Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.

Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.

Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.

Reducing agent : It is defined as the agent which helps the other substance to reduce and itself gets oxidized. Thus, it will undergo oxidation reaction.

Oxidizing agent : It is defined as the agent which helps the other substance to oxidize and itself gets reduced. Thus, it will undergo reduction reaction.

The given chemical reaction is,

SO_4^{2-}+2NO_2+H_2O\rightarrow H_2SO_3+2NO_3^-

This reaction is a redox reaction in which nitrogen shows oxidation reaction because the oxidation state of 'N' changes from (+4) to (+5) and sulfur shows reduction reaction because the oxidation state of 'S' changes from (+6) to (+4).

In the redox reaction NO_2 act as reducing agent and SO_4^{2-} act as an oxidizing agent.
