Answer:
Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.
Atomic number = No. of proton = 1
so, your answer is 1
Answer:
The correct answer is: <em>The addition of water will change the concentration of the substances in equilibrium.</em>
Explanation:
For chemical reactions, the equilibrium constant is defined as the ratio between the concentration of products and reactants. In this expression pure substances should not be written, like pure liquids and gases. Since water is a pure liquid should not appear in the equilibrium. However, water is the solvent of all the solutes or substances in the reaction, thus the addition of water will make all the substances to be diluted. Also, because of the Le Châtelier principle the equilibrium should be re-establish and the concentrations whitten in the equilibrium constant should change too.
Sodium oxide and carbon dioxide
Explanation:
When sodium carbonate decomposes sodium oxide and carbon dioxide is produced:
Na₂CO₃ → Na₂O + CO₂
- This kind of reaction is known as decomposition reaction.
- In a decomposition reaction,
- In this kind of reaction, two or more products form from a single reactant.
- The breakdown of a compound into its component individual elements or other compounds falls into this reaction category.

Explanation:
When an atom's outermost orbital gains or loses electrons (also known as valence electrons), the atom forms an ion. An ion with more protons than electrons carries a net positive charge and is called a cation. An ion with more electrons than protons carries a net negative charge and is called an anion
