Answer:
Which statements describe polyatomic ions? Check all that apply.
Polyatomic ions have many charges.
Polyatomic ions have one overall charge.
Polyatomic ions repel other ions to form ionic bonds.
Polyatomic ions attract other ions to form ionic bonds.
Polyatomic ions are made up of only one type of atom.
Polyatomic ions are made up of two or more types of atoms.Explanation:
Ammonium perchlorate appears as a white, crystalline solid or powder. Classified as a division 1.1 explosive if powdered into particles smaller than 15 microns in diameter or if powdered into larger particles but thoroughly dried. Does not readily burn, but will burn if contaminated by combustible material. May explode under prolonged exposure to heat or fire. Used to make rocket propellants, explosives, pyrotechnics, as an etching and engraving agent, and in analytical chemistry.
Hmm trick question here's my answer: the content: protons charge the electrons into its usage , the size: 1.6fm if I'm wrong sorry if I'm right: HA IN YOUR FACE HA!!!
Answer:
Gravitational to Mechanical to electrical
Explanation:
In a hydropower dam, the gravitational potential energy is converted to mechanical energy which in turn produces electrical energy.
- The gravitational potential energy is due to the water overhead and the position of water inside the dam.
- The height and quantity of water determines the magnitude of the gravitational potential energy.
- Then, this energy is released when it falls on turbines and it drives them.
- As the turbine moves, mechanical energy is produced.
- The turbine is connected through a dynamo which produces a electric current by the turning action.
Using physical evidence from multiple different sources, there’s lots of other ways but that’s a starting point
