The elements in Group 1 have similar chemical properties. Descnbe one chemical reaction which shows that lithium, sodium and potassium (using a group 7 element)
react in the same sort of way.
You should say what you would react them with and what substances would be
produced.​

h let me think

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest
