Answer:

292.5 g

Explanation:

We know the formula:

No of moles = Mass ÷ Mr of the Compound

We need to find the mass, so make Mass as the subject of the formula.

Mass = No. of moles × Mr of the Compound

We know the no. of moles, as per given in question which is 5 moles.

Find the Mr of NaCl

Mass of Na = 23

Mass of Cl =35.5

Mr of NaCl = 23 + 35.5 = 58.5

Fill in the values in the formula.

Mass = 5 moles × 58.5

Mass = 292.5 g

g Select the correct statements. I. Reduction is the loss of electrons, and oxidation is the gain of electrons II. Reduction is

Karolina [17]

Answer: The correct answer is Option D.

Explanation:

Reduction reaction is defined as the reaction in which a substance gains electrons. Here, the oxidation state of the substance decreases.

$X^{n+}+ne^-\rightarrow X$

Oxidizing agents are the agents that helps in the oxidation of other substance and itself gets reduced. These agents undergoes reduction reactions.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. Here, oxidation state of the substance increases.

$X\rightarrow X^{n+}+ne^-$

Reducing agents are the agents that helps in the reduction of the other substance and itself gets oxidized. These agents undergoes reduction reactions.

Oxidation state is the number which is given to an atom when it looses or gains electron. It is written as a superscript. In a compound, the total charge is equal to the sum of the charges of all atoms in that compound. For Example: In $MnO_4^-$ , manganese has +7 oxidation number and oxygen has -2.

So, the charge on the compound = $[=7+(4\times (-2))]=-1$

Hence, the correct answer is Option D.
