Most likely, exothermic processes are what cause the light that fireflies emit. because fuel and oxygen undergo a chemical process that produces carbon dioxide and water.
In thermochemistry, an exothermic process is one "for which the overall standard enthalpy change H is negative." Exothermic processes typically result in heat. A reaction for which the overall standard Gibbs energy change G is negative is what the term "reaction" according to the IUPAC means.
The exergonic response and the phrase are commonly mistaken. A very exothermic reaction will often accompany an exergonic reaction since "H" significantly contributes to "G." The majority of the remarkable chemical reactions presented in classrooms are exothermic and exergonic processes.
On the other hand, an endothermic reaction typically produces heat and is brought on by a rise in the entropy of the system.

The atom present in Option (1) most likely to form cation with a charge of +1
<h3>
What is a Cation ?</h3>
A cation has more protons than electrons, consequently giving it a net positive charge.
For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.
The atoms present in Option 1 have one eletron in its outermost shell therefore, it is easy for the atom to lose one elecron than more electron and to attain stable electronic confiuration.
Hence, The atom present in Option (1) most likely to form cation with a charge of +1

Answer:
The bond that will be most polar amongst all these will be C-F.
Explanation:
As we know,
1 D = 3.34 × 10⁻³⁰ C.m
So,
1.44 D = ?
Solving for 1.44 D,
= (3.34 × 10⁻³⁰ C.m × 1.44 D) ÷ 1 D
1.44 D = 4.80 × 10⁻³⁰ C.m
Dipole Moment is given as,
Dipole Moment = q × r
Solving for q,
q = Dipole Moment / r ------ (1)
Where,
Dipole Moment = 4.80 × 10⁻³⁰ C.m
r = 163 pm = 1.63 × 10⁻¹⁰ m
Putting values in eq. 1,
q = 4.80 × 10⁻³⁰ C.m / 1.63 × 10⁻¹⁰ m
q = 2.94 × 10⁻²⁰ C
As,
1.602 × 10⁻¹⁹ C = 1 e⁻
So,
2.94 × 10⁻²⁰ C = X e⁻
Solving for X,
X = (2.94 × 10⁻²⁰ C × 1 e⁻) ÷ 1.602 × 10⁻¹⁹ C
= 0.183 e⁻
Result:
So one element is containing + 0.183 e⁻ while the other element is containing - 0.183 e⁻.
