Webb5 feb. 2024 · Sprinkle salt onto the ice or make little salt piles on top of the pieces. Experiment. Dot the surface with coloring. The coloring doesn't color the frozen ice, but it follows the melting pattern. You'll be able to see channels, holes, and tunnels in the ice, plus it looks pretty. You can add more salt and coloring, or not. Webb30 juli 2024 · So, the completed thermochemical reactions are: H 2 O (s) → H 2 O (l); ΔH = +6.00 kJ H 2 O (l) → H 2 O (g); ΔH = +40.7 kJ b) Now we know that: 1 mol H 2 O (s) = 18.02 g H 2 O (s) ~ 6.00 kJ So, using this conversion factor: 0.800 kJ x 18.02 g ice / 6.00 kJ = 2.40 g ice melted Answer a) H 2 O (s) → H 2 O (l); ΔH = +6.00 kJ
