Final answer:
The unknown substance exhibits physical properties of inorganic compounds, like being insoluble in water and non-magnetic, and a chemical property of reactivity with acid producing bubbles, suggesting the possible release of gas like carbon dioxide. It likely has high melting points and is nonflammable.
Step-by-step explanation:
The properties described are:
- Insoluble in water: This means that the substance does not dissolve in water. It remains separate from the water, forming a separate layer or settling at the bottom.
- Non-magnetic: The substance does not have any magnetic properties. It is not attracted to magnets.
- Bubbles in the presence of an acid: When the substance comes into contact with an acid, it reacts and releases gas bubbles. This indicates that it is undergoing a chemical change.
