<span>Well, for one, they have the same amount of electrons in the outmost shell: Group 1 has 1, Group 2 has 2 etc...They all share similar chemical properties, for example Group 6 (?) S and Se both are acidic oxides.</span>
3.9L
Explanation:
Initial volume = 25L
Final volume = 28.9L
The initial volume is the volume of the liquid without the metal in originally in the container. It is 25L
After adding the metal, the volume changes to 28.9L
Final volume = Initial volume + volume of metal
To find the volume of metal make it the subject of the expression;
Volume of metal = Final volume - initial volume = 28.9 - 25 = 3.9L
The volume of irregular solids are measured by immersing them in water. The change in volume gives their volume.
Sometimes the volume of water displaced is the volume of the solid.

Answer:
You are moving because the Earth and everything in our solar system is constantly moving. ... As the Earth rotates, it also moves, or revolves, around the Sun. The Earth's path around the Sun is called its orbit. It takes the Earth one year, or 365 1/4 days, to completely orbit the Sun.
The theory of evolution was proposed by Darwin.
