The balanced thermochemical equation is
KBr ------- K + 1/2 Br2
<h3>What is thermochemical equation? </h3>
A Thermochemical Equation is defined as the balanced stoichiometric chemical equation which includes the enthalpy change, ΔH.
The chemical equation for the decomposition of potassium bromide to its constituent elements bromine ans potassium :
KBr ----- K + Br2
The balanced thermochemical equation of the decomposition of potassium bromide to its constituent elements potassium and bromide as follows
KBr ------- K + 1/2 Br2
As the heat is absorbed in this reaction therefore, heat is positive.
Thus, we concluded that the balanced thermochemical equation is
KBr ------- K + 1/2 Br2

I would see chemical constitution and physical components are not changed.
Because physical reaction won't change the component itself
The carboxyl group in the amino acid is always acidic
Answer:
f = 0.83 ×10¹⁵s⁻¹
Explanation:
Given data:
Energy of ray = 5.5 ×10⁻¹⁹ J
Frequency = ?
Solution:
Formula:
E = hf
f = E/h
J = Kg . m².s⁻²
f = 5.5 ×10⁻¹⁹ Kg . m².s⁻² / 6.63 ×10⁻³⁴ m²Kg/s
f = 0.83 ×10¹⁵s⁻¹
