A redox reaction is a reaction that involves both reduction and oxidation, it involves a reducing agent which looses electrons and undergoes oxidation and an oxidizing agent that gains electrons (reduction). I believe the following are true about redox reactions; Electrons move from one substance to another, One atom gains electrons and one looses electrons.

<u>Answer:</u> The correct answers are Option A and Option B.

<u>Explanation:</u>

Oxidation-reduction reaction or redox reaction is the reaction in which oxidation and reduction reactions occur simultaneously.

Oxidation reaction is the reaction in which an atom looses its electrons. The oxidation state of the atom increases.

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

Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation state of the atom gets reduced.

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

In a redox reaction, one atom gain electron and another atom looses electron or it can also be said that electrons are transferred from one substance to another substance.

Thus, the correct answers are Option A and Option B.

How many moles of CaO will be produced from 23.9 g of Ca?<br>2Ca(s) + O2(g) – 20:0(3)<br>mol​
inessss [21]

Answer:

0.6 moles of CaO will produced.

Explanation:

Given data:

Mass of calcium = 23.9 g

Moles of CaO produced = ?

Solution:

Chemical equation:

2Ca + O₂ → 2CaO

Number of moles of calcium:

Number of moles = mass/ molar mass

Number of moles = 23.9 g / 40 g/mol

Number of moles = 0.6 mol

Now we will compare the moles of calcium and CaO.

            Ca         :          CaO

              2          :          2

            0.6         :        0.6

 0.6 moles of CaO will produced.

Some magnesium powder was mixed with some copper( II)oxide and heated strongly. there was a victorious reaction producing a lot
-BARSIC- [3]

Reaction:

\mathrm{Mg \: + \: CuO \rightarrow Cu\: + \: MgO}

Magnesium is a stronger reducing agent than copper and is thus able to reduce copper(II) oxide.

Products of the reaction: Magnesium oxide and metallic copper.
