Question 4 "All samples of a given compound have the same proportion of their constituent elements" is O the law of constant composition the law of conservation of matter 67 O does not apply to things like salt or sugar O only true in some situations Question 5 Chemical energy is stored in wood through the electrostatic forces between atoms and molecules. When this wood is burned...[select all that apply] energy is conserved during this physical change the wood is converted to productes that are more energetically stable energy is conserved during this chemical change o the chemical potential energy is converted to thermal energy the chemical kinetic energy is converted to potential energy o the wood is converted to products with higher potential energy and so are less stable the energy is lost permanently
