<span>An antifreeze is an additive which lowers the freezing point of a water-based liquid. An antifreeze mixture isused to achieve freezing-point depression for cold environments and also achieves boiling-point elevation to allow higher coolant temperature.</span>
Answer:
Lowest: NF3, PBr3, NCl3: Highest
Explanation:
NCl3 is the highest because of the inoic bonds
PBr3 is higher than NF3 because of the larger molar mass.
One way is too to collect just solute sugar, heat over very low heat to evaporate as much water as possible to give yourself a saturated solution. Then crystallize sugar and filter in the lab you'd wash with a suitable solvent and dry under vacuum To collect just the solvent water distill over moderate heat to collect water.
Answer:
Weather forecasts are made by collecting as much data as possible about the current state of the atmosphere (particularly the temperature, humidity and wind) and using understanding of atmospheric processes (through meteorology) to determine how the atmosphere evolves in the future.
