Answer:
101.63° C
Explanation:
Volume expansivity γa = γr - γ g = 18 × 10⁻⁵ - 2.0 × 10⁻⁵ = 16 × 10⁻⁵ /K
v₂ - v₁ / v₁θ = 16 × 10⁻⁵ /K
(500 - 492 ) mL / (492 × 16 × 10⁻⁵) = θ
θ = 101.63° C
I don’t understand. Is there a picture? Where are the options?
Answer:
The main difference between distillation and fractional distillation are:Simple distillation separate liquid with boiling point gaps of at least 50 degrees whereas fractional distillation separates liquid with closer boiling point.

Answer:
D. C + 2H₂ + ¹/₂O₂ → CH₃OH
Explanation:
The standard enthalpy of formation -ΔHf- is defined as the enthalpy change for the formation of 1 mol of a compound from its component elements.
Component elements are any element in its standard state.
For CH₃OH(l) at 25°C and 1 atm of pressure, the component elements are C(s), H₂(g) and O₂(g)
Thus, the equation that represent the standard enthalpy of formation of CH₃OH(l) is:
D. C + 2H₂ + ¹/₂O₂ → CH₃OH
