Answer: The net ionic equation for the given reaction is
Explanation:
Net ionic equation of any reaction does not include any spectator ions.
Spectator ions are the ions which do not get involved in a chemical equation. It is also defined as the ions that are found on both the sides of the chemical reaction when it is present in ionic form.
The chemical equation for the reaction of hydrochloric acid and potassium sulfite is given as:
Ionic form of the above equation follows:
As, potassium and chloride ions are present on both the sides of the reaction, thus, it will not be present in the net ionic equation.
The net ionic equation for the above reaction follows:
Hence, the net ionic equation for the given reaction is written above.
Final answer:
The net ionic equation for the reaction between hydrochloric acid and potassium sulfite is H+ (aq)+ SO3^2- (aq) → H+ (aq) + SO3^2- (aq), following the solubility trends of sulfates and sulfites under standard conditions.
Explanation:
The reaction between excess hydrochloric acid (HCl) and potassium sulfite (K2SO3) is a typical acid-base neutralization reaction. In the initial step, potassium sulfite dissociates into its ions in the aqueous solution:
K2SO3 (aq) → 2K+ (aq) + SO3^2- (aq)
Hydrochloric acid, being a strong acid, also dissociates completely:
HCl (aq) → H+ (aq) + Cl- (aq)
The hydrogen ion from the acid then reacts with the sulfite ion to form sulfuric acid and water, creating a net ionic equation :
2H+ (aq) + SO3^2- (aq) → H2SO3 (aq)
Because of the solubility trends of sulfates and sulfites under standard conditions, the sulfuric acid produced also dissociates into ions:
H2SO3 (aq) → 2H+ (aq) + SO3^2- (aq)
Therefore, the overall net ionic equation is:
H+ (aq)+ SO3^2- (aq) → H+ (aq) + SO3^2- (aq)

Answer:
0.41 M
Explanation:
A -> B
rate constant (k) = 0.039L/mol s
t = 23
Final concentration, [A] = 0.30M
Initial concentration, [A]o = x
1 / [A] = kt + 1 / [A]o
1 / [A]o = 1 / [A] - kt
1 / [A]o = 1 / 0.30 - 0.039 (23)
1 / [A] = 3.33 - 0.897 = 2.433
[A] = 0.41 M

Explanation:
The bond between , Sodium and Bromine , in sodium bromide salt , is ionic in nature .
Since ,
The difference in the electronegativity of the two atom is high .
According to Pauling scale ,
The Electronegativity of Bromine = 2.96
The Electronegativity of sodium = 0.93
Hence ,
The Difference in electronegativity = ( 2.96 - 0.93 ) = 2.03
Hence ,
The electronegativity difference value is more than 1.8 ,
Therefore,
The bond is ionic in nature .

An element is to an atomas an organ is to a cell. Just as atoms are the fundamental building blocks of elements, cells are the basic units of living organisms.
Elements are composed of atoms, each characterized by a specific number of protons, neutrons, and electrons.
Similarly, organs are composed of cells, each with specialized structures and functions that collectively contribute to the overall function of the organ.
The analogy highlights the hierarchical organization of matter and life, emphasizing how complex structures are formed from simpler components.
Just as elements combine to create diverse substances, cells come together to form intricate organs essential for life processes.

Consider the ionic equation of this chemical equation. We are given barium chloride and silver nitrate as the reactants, and silver chloride and barium nitrate as the products. We can thus conclude that the ionic equation ( not balanced yet ) should be as follows -
Ba( 2 + ) + Cl ( - ) + Ag ( + ) + NO3 ( - ) ------> AgCl + Ba( 2 + ) + NO3( - )
As you can see these compounds are present in aqueous solutions, and are thus dissociated.

Now let us take a look at the number of elements on the reactant and product sides, and balance this chemical equation out -
Ba( 2 + ) + 2Cl ( - ) + 2Ag ( + ) + 2NO3 ( - ) ------> 2AgCl + Ba( 2 + ) + 2NO3( - )
Solution = Option C!
