Molecules with ionic bonds between their components will dissociate
(fall apart) in water, releasing charged particles called ions.<span>
<span>When the number of protons and electrons are not equal, ion
is formed. There are two types of ions, Cations and anions. Cations are the
positively charged ions and when an atom gains electron, Cation is formed.
Anions are negatively charged ions and when an atom loses electrons, anion is
formed.</span></span>
D - density: 13,534 g/ml
m - mass: 10g
V - volume: ??
_____________
d = m/V
V = m/d
V = 10/13,534
V = 0,7389 ml

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.
