can you answerthe lab questions 1-5?

1. Explain why methanol and sodium carbonate were both able to dissolve in water, but only sodium carbonate was able to conduct electricity in solution. (3 pts) 2. Look up the chemical structures of methane and methanol. Based on their structures, which of the two do you expect to be water soluble? Explain your answer. (4 pts) 3. What are the main structural differences and similarities between methanol and 1-decanol. Explain the observed difference in solubility between methanol and 1-decanol. (4 pts) 4. Based on the solubility curve of KNO3, does solubility increase, decrease or remain constant with temperature? Explain your answer. (2 pts)
5. Four grams (4 g) of NaNO, was dissolved in 10 mL of water and heated to 100 °C. Upon cooling, the salt began to recrystallize at approximately 40 °C. Based on these observations determine whether sodium or potassium nitrate used in your experiment is the more soluble salt. Explain your answer. (4 pts) 6. According to the data obtained from the experiment, do you expect 30 grams of KNO, to dissolve in 25 mL of water at 40°C? Explain. (3 pts)
Concentration Saturation Temperature °C KNO, Trial 1 Trial 2 2 g/5 ml 18.5 °C 26.600 4 g/5 ml 39.900 Soroc 6 g/5 ml 58.4°C 20.20 84.600 75.ac 8 g/5 ml
