The lab question is “based on a substance’s properties, how can you determine whether its bonds are ionic or covalent? ” fill in the box to answer this question with a hypothesis. hypothesis: if a substance contains ionic bonds, then its properties would include . .

If the substance has high melting/boiling point, if it requires high temperature to dissociate into simpler particles, if it's structure is hard and if it conducts heat and electricity quite frequently, then it would be "Ionic compound" otherwise, it will be covalent compound. (compound with covalent bonds).

Substance with ionic bonds, would include... (mentioned in first sentence)

Hope this helps!

The bonds between ionic molecules are very strong. The ionic molecules are crystalline solid, have high boiling point, and show electric conductivity in the solution.

Ionic Bond:

This bond is formed between two ions where one is positive and another is negative. Positively charged elements give electrons to negatively charged elements to complete octet.

Example:

Properties of Ionic Compound:

Usually found as solid crystals.The boiling and melting point is very high.They conduct electricity in water solutions.

Properties of covalent Compound:

Found in all 3 forms in the room temperature.Usually they have relatively low boiling and melting point.They do not conduct electricity.

Hence, If a substance contains ionic bonds, then its properties would include solid crystalline state, high melting point and conduct electricity in the solution.

That result from subduction of oceanic plates beneath lighter continental plates. most of the earth's volcanoes are located around the pacific ring of fire because that the location of most of the earth's subduction zones.

Ithink the answer is a or d.
