which melts at a low temp in a solid nonelectrolyte what type of solid is it

To determine the type of solid that melts at a low temperature in a solid nonelectrolyte, we need to understand the behavior of different types of solids.

1. Molecular Solids: These solids are made up of individual molecules held together by intermolecular forces, such as van der Waals forces and hydrogen bonding. Molecular solids generally have low melting points and do not conduct electricity in either the solid or molten state. Examples include ice (H2O), ethanol (C2H5OH), and sugar (C12H22O11).

2. Ionic Solids: These solids are composed of positively and negatively charged ions held together by strong electrostatic forces. Ionic solids typically have high melting points due to the strong bond between ions. However, they do not conduct electricity in the solid state and only conduct when molten or dissolved in water. Examples include table salt (NaCl), calcium chloride (CaCl2), and magnesium oxide (MgO).

3. Covalent Network Solids: These solids are made up of a three-dimensional network of atoms connected by strong covalent bonds. Covalent network solids have extremely high melting points due to the strong and continuous network of bonds. They generally do not conduct electricity except for a few exceptions, such as graphite and diamond. Examples of covalent network solids include diamond (C), quartz (SiO2), and graphite (C).

Given that the solid in question melts at a low temperature and is a nonelectrolyte, it is most likely a molecular solid. Covalent network solids have high melting points, and ionic solids, although they may have low melting points, tend to conduct electricity when melted.

Please note that this is a general explanation, and there may be exceptions or additional details to consider when classifying specific compounds.
