ΔG⁰ = ΔH⁰ - T ΔS⁰
ΔG⁰ : Standard free energy of formation of acetylene
ΔH⁰ : Standard enthalpy of formation (226.7 kJ/mol)
ΔS⁰ : Standard entropy change (58.8 J / K. mol)
T : Temperature 25°C = 298 K (room temperature)
ΔG⁰ = 226.7 - (298 x 58.8 x 10⁻³) = 209.2 kJ /mol

When the parallel light rays exit a convex lens, it comes away or diverge.
Answer:
D. Two substances mix evenly without reacting.
Explanation:
Solutions are homogenous mixtures of solutes and solvents.
- In a solution, the solute particles are distributed uniformly in the solvent.
- The solute is the substance that is dissolved to make the solution.
- It is usually present in smaller amount than the solvent
- The solvent is the dispersing substance that allows the solute to go into solution.
- The solute could be solid or liquid or gas
- The solvent could be solid or liquid or gas but most times liquid.
