Question

a yellow solid melts at room temperature. it does not conduct electricity when tested. which of these properties does the substance demonstrate that is typical of some covalent compounds? soluble reflective low melting point brittle

Explanation:

Covalent compounds often have weak intermolecular forces, resulting in low melting - points. Melting at room temperature indicates a low melting - point. Solubility, reflectivity, and brittleness are not the most characteristic properties mentioned here to identify covalent compounds compared to the low melting - point property.

Answer:

low melting point
