16.1g of bromine are mixed with 8.42g of chlorite to give an actual yield of 21.1g of bromine monochloride. Solve using factor l
krok68 [10]

The question is incomplete, here is the complete question:

16.1 g of bromine are mixed with 8.42g of chlorine to give an actual yield of 21.1 g of bromine monochloride. Determine the percent yield of the reaction.

<u>Answer:</u> The percent yield of the reaction is 90.71 %.

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}     .....(1)

  • <u>For bromine gas:</u>

Given mass of bromine gas = 16.1 g

Molar mass of bromine gas = 159.8 g/mol

Putting values in equation 1, we get:

\text{Moles of bromine gas}=\frac{16.1g}{159.8g/mol}=0.1008mol

  • <u>For chlorine gas:</u>

Given mass of chlorine gas = 8.42 g

Molar mass of chlorine gas = 71 g/mol

Putting values in equation 1, we get:

\text{Moles of chlorine gas}=\frac{8.42g}{71g/mol}=0.118mol

The chemical equation for the reaction of bromine and chlorine gas follows:

Br_2+Cl_2\rightarrow 2BrCl

By Stoichiometry of the reaction:

1 mole of bromine gas reacts with 1 mole of chlorine gas

So, 0.1008 moles of bromine gas will react with = \frac{1}{1}\times 0.1008=0.1008mol of chlorine gas

As, given amount of chlorine gas is more than the required amount. So, it is considered as an excess reagent.

Thus, bromine gas is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

1 mole of bromine gas produces 2 mole of bromine monochloride

So, 0.1008 moles of bromine gas will produce = \frac{2}{1}\times 0.1008=0.2016moles of bromine monochloride

Now, calculating the mass of bromine monochloride from equation 1, we get:

Molar mass of bromine monochloride = 115.36 g/mol

Moles of bromine monochloride = 0.2016 moles

Putting values in equation 1, we get:

0.2016mol=\frac{\text{Mass of bromine monochloride}}{115.36g/mol}\\\\\text{Mass of bromine monochloride}=(0.2016mol\times 115.36g/mol)=23.26g

To calculate the percentage yield of bromine monochloride, we use the equation:

\%\text{ yield}=\frac{\text{Actual yield}}{\text{Theoretical yield}}\times 100

Actual yield of bromine monochloride = 21.1 g

Theoretical yield of bromine monochloride = 23.26 g

Putting values in above equation, we get:

\%\text{ yield of bromine monochloride}=\frac{21.1g}{23.26g}\times 100\\\\\% \text{yield of bromine monochloride}=90.71\%

Hence, the percent yield of the reaction is 90.71 %.

Compared with the energy it takes to separate oxygen and hydrogen from water. How much energy is released when they recombine?.
Stolb23 [73]

The same amount of energy is released when they recombine.

<h3>How to separate oxygen and hydrogen from water?</h3>
  • Electrolysis is a promising choice for without carbon hydrogen creation from inexhaustible and atomic assets.
  • Electrolysis is the method involved with utilizing power to part water into hydrogen and oxygen.
  • This response happens in a unit called an electrolyzer.
  • Electrolyzers can go in size from little, apparatus size hardware that is appropriate for limited scope dispersed hydrogen creation to huge scope, focal creation offices that could be tied straightforwardly to sustainable or other non-ozone depleting substance radiating types of power creation.
<h3>How Does it Work?</h3>

Like energy components, electrolyzers comprise of an anode and a cathode isolated by an electrolyte. Different electrolyzers capability in various ways, fundamentally because of the different kind of electrolyte material included and the ionic species it conducts.

Crystal structures with ions must have ____________.a. a positive chargeb. a negative chargec. electrical neutralityd. a 2+ char
Inessa05 [86]

Answer:

c. electrical neutrality.

Explanation:

A <em>crystalline  solid</em><em> possesses a rigid and long-range order; its atoms, molecules, or ions occupy  specific positions.</em> The arrangement of such particles in a crystalline solid is such that  the net attractive intermolecular forces are at their maximum.

Ionic crystals, particularly, have two important characteristics:

(1) They are composed of charged species.

(2) Anions and cations are generally quite different in size.

The forces holding the atoms together are electrostatic attractions. Examples of these types of crystals include NaCl, LiF, MgO, CaCO₃.

<u>Since they are composed of anions and cations, in stoichiometric amount, they are to be said electrically neutral.</u>
