Answer:

En química y física, la teoría atómica es una teoría científica sobre la naturaleza de la materia que sostiene que está compuesta de unidades discretas llamadas átomos. Empezó como concepto filosófico en la Antigua Grecia y logró ampliar aceptación científica a principios del siglo XIX cuando los descubrimientos en el campo de la química demostraron que la materia realmente se comportaba como si estuviese hecha de átomos.

La palabra átomo proviene del adjetivo en griego antiguo átomos, que significa «indivisible». Los químicos del siglo XIX empezaron a utilizar el término en relación con el número creciente de elementos químicos irreducibles.1​ Cerca del cambio al siguiente siglo, a través de varios experimentos con electromagnetismo y radiactividad, los físicos descubrieron que los "átomos indivisibles" eran de hecho un conglomerado de varias partículas subatómicas (principalmente, electrones, protones y neutrones), las que pueden existir separadas unas de otras. De hecho, en ciertos entornos extremos, como las estrellas de neutrones, la presión y la temperatura extremas impiden que los átomos puedan existir en absoluto.

Ya que se descubrió que los átomos podían dividirse, los físicos inventaron el término «partículas elementales» para describir las partes "indivisibles", aunque no indestructibles, de un átomo. El campo de ciencia que estudia las partículas subatómicas es la física de partículas y es en este campo donde los físicos esperan descubrir la auténtica naturaleza fundamental de la materia

When ionic solids dissolve in water, they produce soluble aqueous cations and anions. For example, adding MgBr2 solids to water
worty [1.4K]

Answer:

Al(NO3)3(s)--------> Al^3+(aq) + 3NO3^-(aq)

Explanation:

The equation shown above describes the dissolution of Al(NO3)3 in water using the lowest coefficients.

This occurs when solid Al(NO3)3 is added to water. It dissolves to give rise to ions as shown. This is a property of all ionic substances.

Write a balanced chemical equation for the reaction between ammonium
Natasha2012 [34]

Answer:

 (NH₄)₃PO₄ (l) + Al(NO₃)₃(l) -----------→  AlPO₄(l) + 3NH₄NO₃(l)

Explanation:

Data Give:

Reaction between ammonium phosphate solution and solution of aluminum nitrate

  • Write a balanced chemical equation
  • include phase symbols

Details:

To write a balanced chemical equation we have to know formula units of compounds or molecules

Formula units

ammonium phosphate : (NH₄)₃PO₄

aluminum nitrate: Al(NO₃)₃

ammonium nitrate: NH₄NO₃

Now to write a chemical equation

  • we have to write the chemical formulas  or formula unit of each compound
  • write the reactant on left side of the arrow
  • write the product on the right side of the arrow
  • put a plus sign in 2 reactants and products on each side of the arrow
  • balance the equation by putting coefficient with compound formula
  • write the phase symbols on the right corner of the compound formula in brackets

So the Reaction will be

                      (NH₄)₃PO₄ + Al(NO₃)₃ -----------→  AlPO₄ + NH₄NO₃

Now balance the Chemical equation

                     (NH₄)₃PO₄ + Al(NO₃)₃ -----------→  AlPO₄ + 3NH₄NO₃

Now write the phase Symbols

                     (NH₄)₃PO₄ (l) + Al(NO₃)₃(l) -----------→  AlPO₄(l) + 3NH₄NO₃(l)

all compounds in the reaction are in liquid form and soluble in water

*** Note:

There is no aluminum nitrite in chemicals formulas

Also ammonium nitrite can not be used in pure isolated form due to its highly instability
