The table shows columns that Brenda uses for her notes on the properties of elements. Her notes state that some elements can react to form basic compounds. A 3-column table with 2 rows. The first row has entries metals, metalloids, nonmetals. The second row has entries nothing, nothing, nothing.

Where should Brenda place this property in her table?

only in the column for metalloids
only in the column for nonmetals
in the columns for metalloids and for nonmetals
in the columns for metals and for metalloids

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.
