<u>Answer:</u>
<u>Ion</u>
Ion is a charged particle.
A neutral atom contains equal number of positive protons and negative electrons
When an electron is lost or gained the atom becomes a charged particle which is called as an ION.
For example
Na is an atom which contains 11 electrons and 11 protons(= to atomic number)
When Na loses an electron it will have 11 positive proton and 10 negative electron and Thus, Na will become
, a charge particle which we call it as sodium ion.
Cl is an atom which contains 17 electrons and 17 protons(= to atomic number)
When Cl loses an electron it will have 17 positive proton and 18 negative electron and Thus, Cl will become
, a charge particle which we call it as chloride ion.
When an ion is positively charged it is called as a cation
When an ion is negatively charged it is called as an anion.
Salt is formed when an acid reacts with a base.
The cation of the base combines with the anion of the acid to form the salt.

HCl is acid and NaOH is a base forms salt NaCl and water.
is an anion of the acid and
is the cation of the base combines to form NaCl salt .
and
combines to form
In order for a cellular device to operate, it requires battery power, otherwise known as energy.
or you can do this
Us humans consume food so that we can have the sufficient energy to accomplish tasks.
Yes you are correct good job!
Answer:
For most of its active life, a star shines due to thermonuclear fusion of hydrogen into helium in its core, releasing energy that traverses the star's interior and then radiates into outer space. At the end of a star's lifetime, its core becomes a stellar remnant : a white dwarf , a neutron star , or, if it is sufficiently massive, a black hole .
Explanation:
The number of moles of one substance given the amount in mass can be calculated by the use of the molar mass. This is the mass of a compound per 1 mol of the said substance. For, KCl the molar mass is 74.55 g/ mol
148 g / 74.55 g/mol = 2 mol KCl
Hope this answers the question. have a nice day.
