sodium azide nan3 is dissolved in water. acidified silver nitrate is added to the solution and a white precipitate forms. aqueous ammonia is then added to the solution and a white precipitate forms. aqueous ammonia is then added to the white precipitate. the azide ion n3- has similar chemical properties to the cl- ion. what is the formula of the white ppt and what is observed on adding aqueous ammonia?

Elements in group 2 are all called alkaline earth metals. what is most similar about the alkaline earth metals?

Give a real-world example of an energy transformation that uses two of the following forms of energy: chemical, mechanical, nuclear, gravitational, radiant, electrical, thermal (heat), and/or sound.

How is electrolysis most commonly used to produce an energy source? a - splitting water molecules produces oxygen, which organisms breathe to fuel their bodies. b - splitting water molecules produces hydrogen gas, which is used to power machines through hydrogen fuel cells. c - splitting carbon dioxide molecules produces coal, a form of carbon that can be burned to produce heat. d - splitting carbon dioxide molecules produces natural gas, which can be burned to generate electricity in power plants.
