Answer:
Water is polar covalent while isoporopanol is covalent
Explanation:
Water contains polar covalent bonds. Water has a high dipole moment and thus dissolves ionic substances easily such as sodium chloride. Water is also a good electrolyte. Water is not volatile. Water molecules are held together by hydrogen bonds. Isopropanol is a covalent compound. It is non polar and suitable for dissolving non polar substances such as campohor. It is volatile but dissolves in water due the the -OH group present in the molecule.

Answer:
The rest of the wood was converted to gases
Explanation:
According to the law of conservation of mass, the mass on the reactant side must be equal to the mass on the product side. When wood is burned it forms ashes and gases. The mass of the ash plus gases must be equal to the mass of the wood and air used in burning it.
If 3g of wood were burned and the ashes produced weighs 1.2g, it means that the rest 1.8g have been converted to gases
