Explanation:
covalent bond poor thermal conductivity
molecular compounds
metallic bond ductile
electron sea model
ionic bond crystalline
hard and brittle
Covalent compounds have the following properties:
- Gases and volatile liquids or low melting point solids
- Often insoluble in polar solvents
- Mainly non - conductors
- Have slow reactions
Metallic compounds:
- Have good malleability, ductility, electrical and thermal conductivity.
- A large sea of electron by jointly packed atoms.
- They are mostly in metals
- Accounts for the bulk of the physical properties displayed by metals
Ionic compounds:
- High melting and boiling point
- Soluble in polar liquids
- Conducts electricity in molten or aqueous forms.
- Mostly crystalline solids
- Usually hard and brittle
- Undergoes fast chemical reactions

<u>Answer:</u> In a chemical reaction, the total mass of the particles in the system stays the same
<u>Explanation:</u>
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side in a chemical reaction.
Every balanced chemical reaction follows law of conservation of mass.
<u>For Example:</u> Formation of water molecule

Total mass on reactant side = ![[2(2\times 1)+(2\times 16)]=36g/mol](https://tex.z-dn.net/?f=%5B2%282%5Ctimes%201%29%2B%282%5Ctimes%2016%29%5D%3D36g%2Fmol)
Total mass on product side = ![[2((2\times 1)+16)]=36g/mol](https://tex.z-dn.net/?f=%5B2%28%282%5Ctimes%201%29%2B16%29%5D%3D36g%2Fmol)
Hence, in a chemical reaction, the total mass of the particles in the system stays the same
