Answer:
The specific rotation of D is 11.60° mL/g dm
Explanation:
Given that:
The path length (l) = 1 dm
Observed rotation (∝) = + 0.27°
Molarity = 0.175 M
Molar mass = 133.0 g/mol
Concentration in (g/mL) = 0.175 mol/L × 133.0 g/mol
Concentration in (g/mL) = 23.275 g/L
Since 1 L = 1000 mL
Concentration in (g/mL) = 0.023275 g/mL
The specific rotation [∝] = ∝/(1×c)
= 0.27°/( 1 dm × 0.023275 g/mL
)
= 11.60° mL/g dm
Thus, the specific rotation of D is 11.60° mL/g dm

The temperature at which a given solid will melt is called melting point.
The melting range is the span of temperature from the point at which the crystals first begin to liquefy to the point at which the entire sample is liquid.
Answer:
Molecules in the gas move faster due to the fact they have more energy
Explanation:
If you put more heat the higher the volume will be. Less heat means less volume.
