Please explain how the following two combustion (burning) reactions appear to disobey the law of conservation of Mass: a When a diamond is burned, the mass that remains is zero. B. When a piece of wood is burned, the leftover ashes weight less than the wood. Upon further investigation, it is noted that CO2 is vented off from both reactions. With this additional information, state how you can prove the diamond is made of pure carbon ans yet the wood is not.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

c is the answer because when something is left after something evaporates that shows the chemical change.

you gotta add the following molecules so we can give u an answer

explanation:
