How do you determine if an element or compound is Aqueous, Solid, Liquid, or Gas just looking at a periodic table. Also, how do you determine if a compound or element is insoluble or soluble by looking at just the periodic table.

What's the net ionic equation for NH4Cl reacting with; Na2CO3, K2CO3,K3PO4, and NaOH

Thanks so much I love you all!

To determine the physical state of an element or compound (aqueous, solid, liquid, or gas), you would need to refer to additional information beyond just the periodic table. The periodic table provides information about the atomic number, symbol, atomic mass, and often the atomic radius and electronegativity. However, it does not indicate the physical state of the element or compound.

The physical state of an element or compound is determined by the temperature and pressure conditions. Generally, at room temperature (around 25°C or 77°F) and standard pressure (1 atmosphere or 101.3 kPa), most elements and compounds can exist in their typical physical states:

1. Aqueous: Refers to a substance dissolved in water. For example, NaCl dissolved in water would be written as NaCl(aq).

2. Solid: Refers to a substance with a definite shape and volume. For example, iron (Fe) is a solid at room temperature and pressure and would be represented as Fe(s) in a chemical equation.

3. Liquid: Refers to a substance with a definite volume but no fixed shape. An example would be water (H2O) which is a liquid at room temperature and pressure, written as H2O(l).

4. Gas: Refers to a substance that does not have a definite volume or shape. For example, oxygen gas (O2) is a gas at room temperature and pressure, and it would be written as O2(g).

To determine if a compound or element is insoluble or soluble, you will need additional information beyond just the periodic table. Solubility is dependent on various factors such as the nature of the compounds, temperature, and pressure. The periodic table can provide some insights into the solubility of some ionic compounds based on the elements present and their position on the periodic table. However, it is not sufficient to make a definitive determination.

To determine solubility, it is important to refer to solubility tables or references that provide information on the solubility of specific compounds under specific conditions (temperature, pressure). These references list the compounds and their corresponding solubility as either being soluble (able to dissolve) or insoluble (unable to dissolve) in water or other solvents.

Regarding your question about the net ionic equation for NH4Cl reacting with various compounds, let's go through each reaction:

1. NH4Cl + Na2CO3:
The chemical equation is NH4Cl + Na2CO3 → 2NaCl + CO2 + H2O
To write the net ionic equation, we need to split the soluble compounds into their respective ions:
NH4+(aq) + Cl-(aq) + 2Na+(aq) + CO3^2-(aq) → 2Na+(aq) + Cl-(aq) + CO2(g) + H2O(l)
Net ionic equation: NH4+(aq) + CO3^2-(aq) → CO2(g) + H2O(l)

2. NH4Cl + K2CO3:
The chemical equation is NH4Cl + K2CO3 → 2KCl + CO2 + H2O
Net ionic equation: NH4+(aq) + CO3^2-(aq) → CO2(g) + H2O(l)

3. NH4Cl + K3PO4:
The chemical equation is 3NH4Cl + K3PO4 → 3KCl + NH4 3PO4
Net ionic equation: 3NH4+(aq) + PO4^3-(aq) → NH4 3PO4(s)

4. NH4Cl + NaOH:
The chemical equation is NH4Cl + NaOH → NaCl + NH3 + H2O
Net ionic equation: NH4+(aq) + OH-(aq) → NH3(g) + H2O(l)

Note that the net ionic equation represents only the species that are directly involved in the reaction, excluding spectator ions that do not participate in the reaction.

See if you can find one of the periodic table on the internet that shows pictures of the elements. If you do you will see that the vast majority of the elements are shiny metal solids. Those that are not shiny metal solids are the exceptions.

There are only two elements (mercury and bromine) that are liquids at 25C.

There are a small number of elements that are gases at room temperature whcih includes hydrogen. They also include all the inert or noble gases, which are those elements in Group 18: helium, neon, argon, krypton, xenon and radon.

We also know that the halogens fluorine and chlorine are gases at room temperature (25C). That leaves nitrogen and oxygen as the last of the elements that are gases at room temperature. All of these elements are nonmetals or halogens or inert gases, and apart from the inert gases are towards the top of the periodic table.
