The net ionic equation: Ag⁺ (aq) + Cl⁻(aq) -> AgCl (s)

<h3>Further explanation </h3>

The electrolyte in the solution produces ions.

The equation of a chemical reaction can be expressed in the equation of the ions

For strong electrolytes (the ionization rate = 1) is written in the form of separate ions, while the weak electrolyte (degree of ionization <1) is still written as an un-ionized molecule

In the ion equation, there is an ion spectator that is the ion which does not react because it is present before and after the reaction

When these ions are removed, the ionic equation is called the net ionic equation

For gases and solids including water (H₂O) can be written as an ionized molecule

So only the dissolved compound is ionized ((expressed in symbol aq)

Formation of precipitating compounds that cause reactions can occur from double-replacement reactions

Solubility Rules:

  • 1. soluble compound

All compounds of Li⁺, Na⁺, K⁺, Rb⁺, Cs⁺, and NH₄⁺

All compounds of NO₃⁻ and C₂H₃O₂⁻

Compounds of Cl⁻, Br⁻, I⁻ except Ag⁺, Hg₂²⁺, Pb²⁺

Compounds of SO₄²⁻ except Hg₂²⁺, Pb²⁺, Sr²⁺, Ba²⁺

  • 2. insoluble compounds

Compounds of CO₃²⁻ and PO₄³⁻ except for Compounds of Li +, Na +, K +, Rb +, Cs +, and NH₄ +

Compounds of OH− except Compounds of Li +, Na +, K +, Rb +, Cs +, NH₄⁺, Sr²⁺, and Ba²⁺

The reaction between AgNO₃ (aq) and NaCl (aq)

AgNO₃ (aq) + NaCl (aq) ⇒AgCl (s) + NaNO₃ (aq)

AgCl is an insoluble compound, so reactions can take place and double-replacement reactions occur

Complete ion reaction:

\rm Ag ^ ++ NO_3 ^ - + Na ^ ++ Cl ^ -  \Rightarrow AgCl (s) + Na ^ ++ NO_3 ^ - \\\\ spectator \: ions: Na ^ + \: and \ : NO_3 ^ - \\\\ net \: ionic \: equation: Ag ^ ++ Cl ^ - \Rightarrow AgCl (s)

An ionic equation refers to a chemical equation where the electrolytes in aqueous solution are demonstrated as dissociated ions. Generally, this is a salt dissolved in water, where the ionic species are succeeded by (aq) in the equation, to suggest that they are in aqueous solution.  

Net ionic equation refers to a chemical equation for a reaction that lists only those species that takes part in the reaction. It is an equation, which demonstrates only the reactants taking part in the formation of a precipitate.  

In the given case, balanced chemical equations is,  

AgNO₃ (aq) + NaCl (aq) = AgCl (s) + NaNO₃ (aq)

Complete ionic equation:  

Ag⁺ (aq) +NO₃⁻ (aq) + Na⁺ (aq) + Cl⁻ (aq) = AgCl (s) + Na⁺ (aq) + NO₃⁻ (aq)

Net Ionic equation:  

Ag⁺ (aq) + Cl⁻ (aq) = AgCl (s) (Silver chloride settles as white precipitate)

Identify the products formed in this Brønsted-Lowry reaction.<br><br> HPO2−4+NO−2↽−−⇀acid+base
klemol [59]

Answer: The products formed in this Bronsted-Lowry reaction are HNO_{2} and PO^{2-}_{4}.

Explanation:

According to Bronsted-Lowry, acids are the species which donate hydrogen ions to another specie in a chemical reaction.

Bases are the species which accept a hydrogen ion upon chemical reaction.

For example, HPO^{2-}_{4} + NO^{-}_{2} \rightleftharpoons HNO_{2} + PO^{2-}_{4}

Here, the products formed in this Bronsted-Lowry reaction are HNO_{2} and PO^{2-}_{4}.

Thus, we can conclude that the products formed in this Bronsted-Lowry reaction are HNO_{2} and PO^{2-}_{4}.

A compound has the empirical formula CH2O. If the compound’s molecular mass is 180 g/mol, determine the molecular formula of the
Umnica [9.8K]
The molecular formula will be a multiple of the empirical CH2O. One unit of CH2O has a mass of 12+2*1+16 = 30 g. This means that if our compound has a molecular mass of 180 g/mol, we can divide 180 / 30 = 6 units, and our compound has 6 units of CH2O. This means that its molecular formula is C6H12O6.

A 150.0mL sample of an aqueous solution at 25C contains 15.2mg of an unknown nonelectrolyte compound. If the solution has an osm
Nookie1986 [14]

Answer:

MM = 225.11 g/mol

Explanation:

In this case, let's analyze the data.

We have a 15.2 mg of an unknown electrolyte in 150 mL of solution. The osmotic pressure is 8.44 Torr, and we want the molecular mass of the unknown.

The osmotic pressure can be calculated using the following expression:

π = CRT   (1)    

π: osmotic pressure (8.44 Torr * 1 atm / 760 Torr = 0.011 atm)

C: Concentration of the unknown in the solution

R: universal constant of gases (0.082 L atm / K mol)

T: temperature in Kelvin (25 + 273 = 298 K)

From this expression, we can either solve for C, and then use another expression to calculate the molecular mass, or we can just replace the expressions in the above formula, to get the direct molecular mass. In this case, we'll follow the second method.

Concentration or molarity of a substance can be calculated using:

C = moles / V  (2)

And moles can be calculated using this expression:

moles = m / MM   (3)

Replacing (3) in (2), and then in (1) we have:

C = m / MM * V

π = m * RT / MM * V   (4)

and now, we can solve for MM:

MM = mRT / π V  (5)

Now, we just need to replace the given data into the above expression to get the value of the molecular mass:

MM = (15.2 / 1000) * 0.082 * 298 / 0.011 * 0.150

<h2>MM = 225.11 g/mol</h2>

Hope this helps
