<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 
If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change to reestablish equilibrium. If a chemical reaction is at equilibrium and experiences a change in pressure, temperature, or concentration of products or reactants, the equilibrium shifts in the opposite direction to offset the change. This page covers changes to the position of equilibrium due to such changes and discusses briefly why catalysts have no effect on the equilibrium position.
For example, if the system is changed in a way that increases the concentration of one of the reacting species, it must favor the reaction in which that species is consumed. In other words, if there is an increase in products, the reaction quotient, Qc, is increased, making it greater than the equilibrium constant, Kc.
Answer:
Magnesium bromide, MgBr2, and water, H2O.
Explanation:
Hello!
In this case, since HBr is an acid and Mg(OH)2 is a base, an acid-base reaction is undergone, by which a salt and water are produced as neutralization products:
However, it need to be balanced since two bromine atoms are produced, therefore we write:
Thus, the products are magnesium bromide, MgBr2, and water, H2O.

That is true, the potential energy they possessed at the airplane door would be converted to kinetic energy. And if they driver is high up, he has further to fall. As the skydivers jump, the energy would be converted to kinetic energy.
Answer:
11.
Explanation:
[OH⁻] = 0.001 M.
∵ pOH = - log[OH⁻]
∴ pOH = - log(0.001 M) = 3.
<em>∵ pH + pOH = 14.</em>
∴ pH = 14 - pOH = 14 - 3 = 11.
