Answer:
physical
Explanation:
because if you let it cool down it will turn back into its original form
2.00 g of PbCl2 at 80°C
100.2 g of NaNO3 at 60°C
128 g of KI at 0°C
75.5 g of LiCl at 20°C
8.22 g of Ba(OH)2 at 40°C
Answer:
1) unsaturated
2) unsaturated
3) saturated
4) unsaturated
5) saturated
Explanation:
A solution with solute that dissolves until it is unable to dissolve anymore, leaving the undissolved substances at the bottom., is called saturated. Each solution has a certain amount of mass that can dissolve at certain temperature.
A solution with less solute than the saturated solution, that completely dissolves, leaving no remaining substances., is called unsaturated.
A solution ,with more solute than the saturated solution, that contains more undissolved solute than the saturated solution, is called oversaturated.
A) 2.00 g of PbCl2 at 80°C
⇒ At 80 °C this solution is saturated when there is 2.54 grams of PbCl2 in solution
2.00 < 2.54 This solution is unsaturated
B) 100.2 g of NaNO3 at 60°C
⇒ At 60 °C this solution is saturated when there is 122 grams of NaNO3 in solution
100.2 < 122
This solution is unsaturated
C) 128 g of KI at 0°C
⇒ At 0 °C this solution is saturated when there is 128 grams of KI in solution
This solution is saturated
D) 75.5 g of LiCl at 20°C
⇒ At 20 °C this solution is saturated when there is 83.5 grams of LiCl3 in solution
75.5 < 83.5
This solution is unsaturated
E) 8.22 g of Ba(OH)2 at 40°C
⇒ At 40 °C this solution is saturated when there is 8.22 grams of Ba(OH)2 in solution
This solution is saturated
