An atom gains an electron from another atom. Hence, option B is the correct answer.
<h3>What is an atom?</h3>
An atom is a particle of matter that uniquely defines a chemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons.
When an atom shares electrons with another atom then it results in the formation of a covalent bond.
Whereas when an atom transfer electrons from one atom to another then it results in the formation of an ionic bond.
When the nucleus of an atom splits then it represents a nuclear fission reaction and energy is released during this process.
Hence, option B is the correct answer.

Answer:
Gases are easily compressed. We can see evidence of this in Table 1 in Thermal Expansion of Solids and Liquids, where you will note that gases have the largest coefficients of volume expansion. The large coefficients mean that gases expand and contract very rapidly with temperature changes. In addition, you will note that most gases expand at the same rate, or have the same β. This raises the question as to why gases should all act in nearly the same way, when liquids and solids have widely varying expansion rates.
The answer lies in the large separation of atoms and molecules in gases, compared to their sizes, as illustrated in Figure 2. Because atoms and molecules have large separations, forces between them can be ignored, except when they collide with each other during collisions. The motion of atoms and molecules (at temperatures well above the boiling temperature) is fast, such that the gas occupies all of the accessible volume and the expansion of gases is rapid. In contrast, in liquids and solids, atoms and molecules are closer together and are quite sensitive to the forces between them.

Explanation:
<em>Ferrous Sulphate</em>
<em> is generally found as Lime-Green Crystals. On heating, these crystals almost immediately turn white-yellow. They then, break down to produce an anhydrous mixture of Sulphur Trioxide </em>
<em>, Sulphur Dioxide </em>
<em> as well as Ferric Oxide </em>
<em>.</em>
<em>We can hence, frame a skeletal equation of this reaction and try to balance it.</em>
<em>Hence,</em>
<em>Now,</em>
<em>a)In order to balance it through the 'Hit &Trial Method', we'll follow a series of </em><em>steps</em><em>:</em>
<em>1. First, lets compare the number of Fe (Iron) atoms on the RHS and LHS. We find that, the no. of Fe Atoms on the RHS is twice the number of Fe Atoms on the LHS. We hence, add a co-effecient 2 beside </em>
.
<em>2. Now, Iron atoms, Sulphur Atoms and Oxygen atoms occur 2, 2, 8 respectively on both the sides:</em>
<em> Hence, As all the other elements as well as iron, balance, we've arrived upon our Balanced Equation :</em>
<em> </em>
<em>b) We know that, decomposition reactions are [generally] endothermic reactions in which Large Compounds </em><em>decompose </em><em>into smaller elements and compounds. Here, as Ferrous Sulphate </em><em>decomposes </em><em>into Sulphur Dioxide, Sulphur Trioxide and Ferric Oxide, the reaction that occurs here is </em><em>Decomposition Reaction.</em>
The equation that is balanced among the given options is the first equation NaOH + HCl → NaCl + H2O
From the question,
We are to determine which of the options gives a balanced equation for the reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl) to make table salt (NaCl) and water (H₂O)
To do this, we will check which of the given equations is balanced, by checking the equations one after the other.
First, we will define what is meant by balanced equation.
Balanced equations are those whose coefficients result in equal numbers of atoms for each element in the reactants and products
- For NaOH + HCl → NaCl + H2O
On the reactants side
Na = 1
O = 1
H = 2
Cl = 1
On the products side
Na = 1
O = 1
H = 2
Cl = 1
Since equal number of atoms of each element are present at both the reactants and products sides, then the equation is balanced
- For 2NaOH + 2HCl → 2NaCl + H2O
On the reactants side
Na = 2
O = 2
H = 4
Cl = 1
On the products side
Na = 2
O = 1
H = 2
Cl = 2
The number of atoms of each element present at the reactants side and that present at products side are not equal.
∴ The equation is not balanced
- For 2NaOH + HCl → NaCl + H2O
On the reactants side
Na = 2
O = 2
H = 3
Cl = 1
On the products side
Na = 1
O = 1
H = 2
Cl = 1
The number of atoms of each element present at the reactants side and that present at products side are not equal.
∴ The equation is not balanced
- For NaOH + 2HCl → NaCl + H2O
On the reactants side
Na = 1
O = 1
H = 2
Cl = 2
On the products side
Na = 1
O = 1
H = 2
Cl = 1
The number of atoms of each element present at the reactants side and that present at products side are not equal.
∴ The equation is not balanced
Hence, the equation that is balanced is the first equation NaOH + HCl → NaCl + H2O
