Answer:
Species M. furo and F. catus
Explanation:
When you look at their family name, both species have -<em>lidae </em>at the end, indicating that they are more closely related.
Disagree, because they can come together to form a compound element. Hope it helped!
Lithium is one of element of group 1 of periodic table.
Lithium has the smallest radius than as compared to the other elements, thus the density of the alkali metal is also less.
Lithium when added to water it floats, because of lower density. It eventually fizzes and becomes smaller.
The reaction on lithium and water is:
2Li + 2H₂O --> 2LiOH + H₂ (g)
The hydrogen gas which is liberated is highly flammable.
Thus, lithium salts are insoluble in water.
Density is defined as the mass of a substance per unit volume.
Density = Mass ÷ Volume.
