Do covalent compounds conduct electricity as liquid or solid?
covalent compounds don't conduct electricity in any state.
What is the characteristics of covalent substances?
Covalent substances are made up of molecules held together by covalent bonds, where atoms share electrons. These substances tend to have lower melting and boiling points compared to ionic compounds, and they are typically nonconductors of electricity in their solid state. Covalent substances can exist in various forms, including gases, liquids, and solids.
What are covalent-network solids?
Covalent-network solids are substances in which atoms are bonded together by strong covalent bonds in an extended network structure. This results in materials with high melting points, hardness, and electrical insulating properties. Examples include diamond and silicon carbide.
What is the name of a liquid that solids can dissolve into?
A solvent is a liquid that can dissolve solids, gases, or liquids to form a homogeneous mixture. Water is a common solvent used for dissolving various substances.
Pressure changes have no effect on the entropy of substances in the blank or blank states?
Pressure changes have no effect on the entropy of substances in the solid or liquid states. Entropy is primarily affected by temperature changes and phase transitions rather than pressure variations in these states.

How does waters relative densities as a solid and a liquid differ from that of most other substances?
Water has a lower density as a solid than it does as a liquid. In the vast majority of substances are denser as solids than as liquids.

How are solids designated on the periodic table?
It can be categorised into -Ionic -Covalent molecular -Metallic -Covalent network
What have lower melting points than ionic solids?
Covalent solids typically have lower melting points than ionic solids because the intermolecular forces holding covalent compounds together are weaker than the ionic bonds in ionic solids. Molecular substances, like water and carbon dioxide, also have lower melting points than ionic solids due to the weaker forces between individual molecules.
In what phase are covalent compounds?
Covalent compounds can be solids, liquids or gases.
Can two solids make up a solution?
No, a solution is a homogeneous mixture of two or more substances, usually a liquid (solvent) and a solid, liquid, or gas (solute). Solids cannot make up a solution as they do not dissolve into each other.
What kind of crystalline solids?
It is a network solid, a lattice of many covalent bonds (like diamond, except that it is black rather than transparent).
Are solid liquid and gas phases or substances?
Solids, liquids, gases, and plasmas are all states of matter. Hopefully that helps.
