in table below, there are descriptions of an experiment on samples of three different chemical compounds. decide whether the compound is ionic or molecular, if you can. if there is not enough information to decide, choose cant decide in the third column. compound description ionic or molecular? 1 compound 1 is a yellow - white solid. when heated to melting, it forms an oily yellow liquid, which is a good electrical insulator. ionic molecular (cant decide) 2 compound 2 is a yellow solid made up of clusters of needle - like crystals. its a good electrical insulator when solid, but if crushed and dissolved in water, the solution is a good conductor. ionic molecular (cant decide) 3 compound 3 is a hard white smooth odorless solid, which is insoluble in water. if the flame from an ordinary laboratory burner is held on the solid for 10 minutes, the solid grows hot to the touch but does not soften. ionic molecular (cant decide)
Answer
Explanation:
Step1: Analyze Compound 1
Good electrical insulator when melted, so molecular.
Step2: Analyze Compound 2
Insulator as solid, conductor when dissolved in water, so ionic.
Step3: Analyze Compound 3
Insoluble in water, doesn't soften easily, not enough info to decide.
Answer:
- molecular
- ionic
- (can't decide)
