Asolid mass of 25 g is mixed with 60 g of a solution. a chemical reaction takes place and a gas is produced. the final mass of the mixture is 75 g. what is the mass of the gas released?

Law of conservation of mass

Solid mass(25g)+ solution(60g)---> gas(x)

Total mass of reactants = total mass of products

25 + 60=75+x

85=75+x

10=x

10g

Alkaline Earth Metals are the 2nd Group of Metals on the Periodic Table.

Explanation:

Characteristics:

- Shiny

- Reactive

- Low melting and boiling points

- Low density

- 2 valence electrons

Alkaline Earth Metals cannot be found alone in nature since they are highly reactable (If you've ever thrown barium into a lake, it would cause a massive explosion).
