A student wants to know if the effect of gravity is the same on all objects. She follows these steps: 1. Drop a 5-gram ball, a 10-gram ball, and a 12-gram ball from a height of 10 meters.

2 Record how long it takes for each object to hit the ground

3: ?
Which step should be next?

Choose new balls

Measure the mass of the balls again

Drop the balls from a different height

Perform a second trial

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.
