Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that all matter is made of atoms, which are indivisible.

Gases have high kinetic energy: the molecules are moving much more than in a liquid or solid. You can cut out A and B. In the liquids, the difference is temperature. If a lower temperature is closer to being solid, and a solid has lower kinetic energy than a liquid, then C is the answer. Hope this helps.
Answer:
azufre
Explanation:
El azufre es un mal conductor del calor y aislante de la electricidad.
Answer:
True
Explanation:
N2 + 3h2 - 2NH3 is indeed a balanced equation therefore it is a "true statement" or option A. You can tell this equation is balanced because it has the same number of Nitrogen, and Hydrogen atoms on the same side keeping the equation balanced.
Hope this helps.
Answer:
1. a) Crystalline hydrated salt lose their mass or moisture on exposure to the air and change into amorphous salt, the phenomenon is called efflorescence.
b) Two salts that x could be are gypsum (Caso4.H2O) and copper (II) sulfate (CuSO4.H2O).
Gypsum (Caso4.H2O) form anhydrite(CaSO4), when exposed to air and copper (II) sulfate (CuSO4.H2O) form a white layer of anhydrous copper (II) Sulfate when expose to sir.
2. a) Salt hydrolysis is defined as the ions from salts react with water and form either basic or an acidic solution.
b) Two examples of salts that produce alkaline solutions when dissolving in water are sodium bicarbonate (NaHCO3) and Calcium Carbonate (CaCO3).
