It went under a physical change because it (1) changed color. (2) changed form.
Answer:
Molecular Formula = C6H6
Explanation:
Empirical Formular = CH
Molar Mass = 78.11
Molecular Formular = ?
The Formular relating these parameters is given as;
(Empirical Formula)n = Molecular Formular
where n = Number of moles
CH = 12.0107 + 1.00784 = 13.01854
(13.01854)n = 78.11
n = 78.11 / 13.01854
n = 5.9999 ≈ 6
Molecular Formula = C6H6
Weathering and erosion produce smaller rock particles which, when mixed with dust result in different types of soil.
