Lily is doing a science experiment with a substance in a sealed jar. At first, the substance's molecules are moving around each other. What will
happen to Lily's substance if she transfers energy into the substance and
causes a phase change? After the phase change, the substance's
molecules will move...'
faster, and the substance will be a liquid.

hi my dude or dudette

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.
