A. It would float with about 75% of the cube below the surface of the water and 25% above the surface. b. It would float with about 5% of the cube below the surface of the water and 95% above the surface.

c. It would sink to the bottom

d. It would float with about 50% of the cube below the surface of the water and 50% above the surface.

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

it's c (engineer's do their work with mechanical stuff not on any living being)

the term hydride is commonly named after binary compounds that hydrogen forms with other elements of the periodic table. hydride compounds in general form with almost any element, except a few noble gases. the trends and properties vary according to the type of intermolecular force that bonds the elements together, the temperature, its molecular masses, and other components. hydrides are classified into three major groups, depending on what elements the hydrogen bonds to. the three major groups are covalent, ionic, and metallic hydrides. formally, hydride is known as the negative ion of a hydrogen, h-, also called a hydride ion. because of this negative charge, hydrides have reducing, or basic properties. its special characteristics will be further discussed.
