Define the term saturation for "hydrocarbons", then determine if the following compounds are saturated or unsaturated.C2H6, C3H6, C6H6, C4H10, C5H12

With a suitable example, show the type of hybridization in the following class of hydrocarbon:Alkane

Explain why it is difficult for carbon atom to form five bonds using sp3d orbitals

Calculate the enthalpy of the following chemical reaction: [6]
CS2(ℓ) + 3O2(g) → CO2(g) + 2SO2(g)
Given:
C(s) + O2(g) → CO2(g) ΔH = -393.5 kJ/mol
S(s) + O2(g) → SO2(g) ΔH = -296.8 kJ/mol
C(s) + 2S(s) → CS2(ℓ) ΔH = +87.9 kJ/mol

Calculate the enthalpy of the following chemical reaction: [6]
CS2(ℓ) + 3O2(g) → CO2(g) + 2SO2(g)
Given:
C(s) + O2(g) → CO2(g) ΔH = -393.5 kJ/mol
S(s) + O2(g) → SO2(g) ΔH = -296.8 kJ/mol

When 0.08 moles of NaOH into 500 ml of 0.6 M buffer system at pH 6.6, the ratio of [Salt]/[Acid] becomes 0.1 (adding NaOH does not change volume). What is the pKa of the buffer system?

Draw the structure of the following compound:
● N-ethyl-N-methylbutanamide
● ethyl pent-4-enoate
● 3-methylbutanoic anhydride

What happen to the atomic size if an element or atom when atomic number increases from left to right across the period of a periodic table

Calculate the enthalpy of the following chemical reaction: [6]
CS 2 (ℓ) + 3O 2 (g) → CO 2 (g) + 2SO 2 (g)
Given:
C(s) + O 2 (g) → CO 2 (g) ΔH = -393.5 kJ/mol
S(s) + O 2 (g) → SO 2 (g) ΔH = -296.8 kJ/mol
C(s) + 2S(s) → CS 2 (ℓ) ΔH = +87.9 kJ/mol
