An anion has gained electrons and therefore has more electrons than protons. It has a negative charge.
An example if this doesn't make too much sense.
Charged Atoms: If electrons are removed from an atom, that atom becomes positively charged because it has more positive charge carriers (protons) than negative charge carriers (electrons)
These types of charged atoms are called positive ions or, cations. DEPENDING ON THE CIRCUMSTANCES, the removed electrons can remain free or they may attach themselves to another atom that can accept extra electrons. If this occurs, a negatively charged ion, or anion, is created.
I hope I made this clear enough for anyone who needed help on this. Hope this helps!!! Have a great day :)))
Answer:
(NH4)2CO3(s) → 2 NH3(g) + CO2(g) + H2O(g)
Explanation:
The balanced equation can be written when we know the chemical formula of each reactants and products of the reaction.
Ammonium carbonate = (NH4)2CO3(s)
Ammonia = NH3(g)
carbondioxide = CO2(g)
water = H2O(g)
The ammonium carbonate was decomposed in the reaction , so ,
(NH4)2CO3(s) → NH3(g) + CO2(g) + H2O(g)
The reactant is on the left side while the product is on the right side. Let us balance the equation to make sure every atom of element is same number on both sides of the equation.
(NH4)2CO3(s) → 2 NH3(g) + CO2(g) + H2O(g)
The decomposition of ammonium carbonate upon heating produces ammonia, carbon dioxide, and water. The balanced equation for this decomposition reaction is: (NH4)(HCO3) → NH3 + CO2 + H2O.
The decomposition of solid ammonium carbonate (NH4)(HCO3) upon heating produces ammonia (NH3), carbon dioxide (CO2), and water (H2O) in gas form. This is a specific type of reaction called a decomposition reaction, which breaks down a compound into its constituent parts. The balanced chemical equation informing this process is: (NH4)(HCO3) → NH3 + CO2 + H2O.
Note from this equation, it is clear that the ammonium carbonate completely disappears as it gets converted into gaseous products upon heating.

The solid having the highest melting point is Na₂O and the correct option is option 2.
The melting point of a solid is a measure of the temperature at which it changes from a solid to a liquid state. It is influenced by the strength of the intermolecular forces between the particles in the solid.
Na₂O(s), which is sodium oxide, has the highest melting point among the given options. This is because Na₂O is an ionic compound composed of positively charged sodium ions (Na⁺) and negatively charged oxide ions (O²⁻). Ionic compounds have strong electrostatic forces of attraction between the ions, known as ionic bonds. These bonds require a significant amount of energy to break, resulting in a high melting point.
H₂O(s) (water ice) has a lower melting point because it is a molecular compound held together by weaker hydrogen bonds.
SO₂(s) (sulfur dioxide) and CO₂(s) (carbon dioxide) are molecular compounds with weaker intermolecular forces, such as London dispersion forces, resulting in lower melting points compared to ionic compounds.
Thus, the ideal selection is option 2.
