What gas does Lithium and water make?
2Li (s) + 2H2O(l) = 2LiOH(aq) + H2(g) The products are lithium hydroxide and hydrogen . Visually, when a pellet of lithium is placed on the water surface, it will gently effervese (fizz). NB For any Group 1 metal (M) , Na, K , Rb, Cs, Fr. 2M(s0 + 2H2O = 2MOH(aq) + H2(g) This reactions become more violent on going down the group . Fr (Francium) is never done in the open lab, because Francium is radio-active.
What are the physical properties of lithium Li?
physical characteristics of lithium: it has the ability to float on water because of its low density; and because its so soft, you can cut it with a knife. chemical characteristics of lithium: when combined with water, produces hydrogen gas; and when combined with oxygen, it forms lithium oxide
What substances does krypton react to?
yes it reacts and combines with a halogen called fluorine and can also make calthrates
What are the economic uses of lithium?
Lithium is used in Lithium Batteries, which are used in computers. Also, Lithium is used to make Lithium-Ion batteries, which are used in many portable devices, such as MP3 players. Lithium used to be used to treat Mania Disorder.

Why does iodine turn blue when mixed with tap water?
It chemically reacts to the tap water, so the green in iodine, reacts violently and causes a mixture according to make it blue.
What reacts with water to make hydrogen gas?
Aluminium foil, sodium hydroxide
How do you make P4O10 into ions?
Dissolve into water and it actually reacts with the water to form H3PO4, phosphoric acid.
What is a metal that floats in water?
If you're floating metal on water, there are only a couple or three metals that have a density so low that they'll float on water. Those metals are lithium, potassium and sodium. Any one of these will float on water, and they are listed in order of increasing density with sodium just a bit less dense than water. Note that all of these metals will react violently with water, so we're setting this issue aside here. Be clear about that.
Why necessary to add a drop of water between the slide and the cover?
to make it clear for observation
How many grams of lithium sulfide must be dissolved in 1600 grams of water to make a 2 molal solution?
Don't try this at home, since Li2S can react very violently with water (much like lithium or sodium metal in water).
