When a small piece of lithium is dropped onto the surface of cold water, it reacts vigorously, releasing hydrogen gas and forming lithium hydroxide. This reaction can be exothermic and may result in the production of enough heat to ignite the hydrogen gas.
Pure lithium, (as exposed by a freshly cut surface), oxidizes rapidly in air to form a thin oxide coating, dull silvery-gray in appearance, that thickens over time to a black lithium oxide tarnish. Conditions of high ambient air temperature and humidity hasten this process.
A fresh piece of lithium will react with oxygen in the air to form lithium oxide. This reaction is exothermic and can produce heat, light, and potentially even a fire.
When iodine is dropped on a piece of cotton, it typically appears as a brownish-red color.
which of the following is made up of a repeating pattern of positive and negative ions A. crystal iodide B hydrogen molecule C a piece of graphite D a water molecule
Sodium in its natural state is shiny, like most metals. When sodium interacts with oxygen in the air, it become sodium oxide, which is much more dull. As a result, when you cut into a piece of sodium, you reveal a brand new part of the sodium that has not yet become sodium oxide and is still shiny.

I like don't know!!!!
somebody dropped a piece of cheese..
Decreasing the surface area of a piece of paper reduces the drag force acting on it as it falls through the air. This is because there is less area for air molecules to interact with the paper, resulting in lower air resistance. As a result, the paper falls faster with less air resistance when its surface area is decreased.

Of course not, at least not by ingestion. You would have to have your skull split and then have a piece of the burger dropped in.
Decreasing the surface area of the paper reduces the amount of material exposed to the air, resulting in less air resistance. Air resistance is dependent on the surface area of the object in contact with the air, so decreasing the surface area will decrease the force opposing the paper's fall.
The piece of paper was soggy after he accidentally dropped it in a puddle.
Piece of bread buttered and grilled, hole cut in the center, egg dropped in hole and fried. Great with a piece of cheese.
when you eat a piece of chicken you are developing protein
Air resistance is the key. In a vacuum a piece of paper and a brick, dropped at the same time, will reach the ground at the same time. When atmosphere is added to the mix the papers area figures in when and where the paper will land. The bigger it is the more air it will capture and its' decent will be slowed.
