The question is incomplete, here is the complete question:

Which formula equation shows a reversible reaction?

A: $2Na+F_2\rightarrow 2NaF$

B: $CaCO_3\rightarrow CaO+CO_2$

C: $NH_4Cl(s)\rightleftharpoons 2NH_3(g)+HCl(g)$

D: $2H_2O_2(aq.)+Pt\rightarrow 2H_2O(l)+O_2(g)$

<u>Answer:</u> The reversible reaction is $NH_4Cl(s)\rightleftharpoons 2NH_3(g)+HCl(g)$

<u>Explanation:</u>

Reversible reaction is defined as the reaction in which the products formed react together to give the reactants back. For general reversible chemical equation:

$A+B\rightleftharpoons C+D$

Irreversible reaction is defined as the reaction in which the reactants only lead to products and the reaction do not proceed back. For general irreversible chemical reaction:

$A+B\rightarrow C+D$

For the given options:

The reaction having an equilibrium sign between the reactants and products is equation C.

Hence, the reversible reaction is $NH_4Cl(s)\rightleftharpoons 2NH_3(g)+HCl(g)$

Describe the particle mode of matter. what does the brownian motion tells us about the particles in matter?give other evidence t

svetlana [45]

Answer:

dium (a liquid or a gas). This pattern of motion typically consists of random fluctuations in a particle's position inside a fluid sub-domain, followed by a relocation to another sub-domain. Each relocation is followed by more fluctuations within the new closed volume. This pattern describes a fluid at thermal equilibrium, defined by a given temperature. Within such a fluid, there exists no preferential direction of flow (as in transport phenomena). More specifically, the fluid's overall linear and angular momenta remain null over time. The kinetic energies of the molecular Brownian motions, together with those of molecular rotations and vibrations, sum up to the caloric component of a fluid's internal energy (the Equipartition theorem).

Which net ionic equation best represents the reaction that occurs when an aqueous solution of barium chloride is mixed with an a

vovangra [49]

Answer : The net ionic equation will be:

$Ba^{2+}(aq)+SO_4^{2-}(aq)\rightarrow BaSO_4(s)$

Explanation :

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The balanced molecular equation will be,

$BaCl_2(aq)+Li_2SO_4(aq)\rightarrow 2LiCl(aq)+BaSO_4(s)$

The complete ionic equation in separated aqueous solution will be,

$Ba^{2+}(aq)+2Cl^-(aq)+2Li^+(aq)+SO_4^{2-}(aq)\rightarrow 2Li^+(aq)+2Cl^-(aq)+BaSO_4(s)$

In this equation the species, $Li^+\text{ and }Cl^{-}$ are the spectator ions.

By removing the spectator ions , we get the net ionic equation.

The net ionic equation will be:

$Ba^{2+}(aq)+SO_4^{2-}(aq)\rightarrow BaSO_4(s)$
