The original concentration : 800%

Given

Diluted 1/40

Final concentration 20%

Required

The original concentration

Solution

Dilution is the process of adding solvent to get a more dilute solution.

The moles(n) before and after dilution are the same.

Can be formulated :

 n₁ = n₂

M₁.V₁ = M₂.V₂

diluted 1/40(dilution factor)⇒ V₁/V₂=1/40⇒V₂/V₁=40

M₂ = 0.2(20%)

Input the value for M₁ :

M₁=M₂ x (V₂/V₁)

M₁ = 0.2 x 40

M₂ = 8(800%)

Introduction

As a diligent student of chemistry, you will likely encounter tons of reactions that occur in aqueous solution (perhaps you are already drowning in them!). When ions are involved in a reaction, the equation for the reaction can be written with various levels of detail. Depending on which part of the reaction you are interested in, you might write a molecular, complete ionic, or net ionic equation.

Definitions of molecular, complete ionic, and net ionic equations

A molecular equation is sometimes simply called a balanced equation. In a molecular equation, any ionic compounds or acids are represented as neutral compounds using their chemical formulas. The state of each substance is indicated in parentheses after the formula. [Huh?]

Let's consider the reaction that occurs between \text{AgNO}_3AgNO

Answer:

hydrogen, carbon, oxygen and nitrogen

Explanation:

Most organic compounds are made up of the four elements: hydrogen, carbon, oxygen and nitrogen.

Most organic compounds are made of just four elements are  hydrogen, carbon, oxygen and nitrogen.

The term organic compound is defined as a substance that contains covalently - bonded carbon and hydrogen and often with other elements.

Benzoic acid, aromatic compounds, benzoic aldehyde, propanoic acid, butanoic acid, malonic acid, amines, heterocyclic compounds, VOC, benzoic acid, and diethyl malonate are some examples of organic compounds.

Carbohydrates, lipids, proteins, and nucleotides are all organic compounds that are required for human function. Because they contain both carbon and hydrogen, these compounds are classified as organic.

Thus, Most organic compounds are made of just four elements are  hydrogen, carbon, oxygen and nitrogen.

Answer: You're Welcome!

Oh, It's False - Kinetic energy depends upon the speed of the object; potential energy depends upon the position of the object.

Answer:

1. 10moles

2. Find the summarized equation below

Explanation:

Mole = mass ÷ molar mass

Molar mass of oleum (H2S2O7) = 1(2) + 32(2) + 16(7)

= 2 + 64 + 112

= 178g/mol

According to the information provided, the mass of oleum is 1780g, hence, the number of moles in it is:

Mole = 1780/178

Mole = 10moles

2. The summarized equation of the contact process is:

1) S + O2 → SO2

2) 2SO2 + O2 → 2SO3

3) SO3 + H2SO4 (conc. sulfuric acid) → H2S2O7

4) H2S2O7 + H2O → 2H2SO4 (dilute sulfuric acid)

Answer:

4.7K

Explanation:

Given parameters:

Initial volume  = 75L

Initial pressure  = 125psi  

        to atm gives 8.5atm

Initial temperature  = 288K

New volume  = 6.1L

New pressure  = 25psi

        to atm gives 1.7atm

Unknown:

New temperature = ?

Solution:

To solve this problem, we use the combined gas law which is given below:

        [tex]\frac{P1 V1}{T1}[/tex]    = [tex]\frac{P2 V2}{T2}[/tex]  

P, V and T are pressure, volume and temperature

1 and 2 are initial and new states

                  [tex]\frac{8.5 x 75}{288}[/tex]   = [tex]\frac{1.7 x 6.1}{T2}[/tex]

        T2  = 4.7K

Answer:

25.2°C

Explanation:

Given parameters:

Energy applied to the water  = 1000J

Mass of water  = 50g

Final temperature  = 30°C

Unknown:

Initial temperature  = ?

Solution:

To solve this problem, we use the expression below:

            H  = m c Ф

H is the energy absorbed

m is the mass

c is the specific heat capacity

Ф is the change in temperature

     1000  = 50 x 4.184 x (30  -  initial temperature )

     1000  = 209.2(30 - initial temperature)

      4.78  = 30 - initial temperature

      4.78  - 30  = - initial temperature

         Initial temperature  = 25.2°C

Answer:

Mass of water produced = 19.8 g

Explanation:

Given data:

Mass of hydrogen peroxide = 37.7 g

Mass of water produced = ?

Solution:

Chemical equation:

2H₂O₂      →        2H₂O  + O₂

Number of moles of H₂O₂:

Number of moles = mass/molar mass

Number of moles = 37.7 g/ 34 g/mol

Number of moles = 1.1 mol

Now we will compare the moles of H₂O₂ and H₂O from balance chemical equation in order to determine the moles of water formed.

                                   H₂O₂      ;           H₂O

                                      2         :             2

                                     1.1         :          1.1

Mass of water formed:

Mass = number of moles × molar mass

Mass = 1.1 mol × 18 g/mol

Mass = 19.8 g

Answer:

3) Compound 1 is ionic, and compound 2 is molecular

Explanation:

Compound-1 is an ionic compound while Compound-2 is a molecular compound. Option 3 is correct.

Ionic Compound:

They are formed when an atom donates its electron to another atom. This results in one positive and one negative ion.

Hence, it is a very strong bond. These compounds have a very high melting and boiling point. They are very good electric conductors in the aqueous solution.

For example- NaCl.

Molecular compounds:

They are compounds that are made up of discrete molecular units. For example- [tex]\bold {H_2O}[/tex]

They have very weak intermolecular bonds hence have low boiling and melting point and do not conduct electricity.

SInce Compound-1 has higher MP and BP and Compound-2 has low melting and boiling point.

Therefore, Compound-1 is an ionic compound while Compound-2 is a molecular compound.

Answer:

0.266 grams of calcium sulfate

Explanation:

We can calculate the mass of calcium sulfate added using the given volume and concentration of the solution:

First we convert 600.0 mL to L ⇒ 600.0 mL equals 0.6000 L (600 ÷ 1000).

0.444 g/L * 0.6000 L = 0.266 g

Thus the answer is 0.266 grams of calcium sulfate.

Answer:

i. 3 moles.

ii. 132.03 grams.

iii. 105.6 grams.

Explanation:

Hello!

In this case, given the balanced chemical reaction, we can proceed as follows:

i. By starting with 5 moles of oxygen, via the 5:3 mole ratio we compute the produced moles of CO2:

[tex]n_{CO_2}=5molO_2*\frac{3molCO_2}{5molO_2} =3molCO_2[/tex]

ii. Now, since we have previously computed the moles of CO2 from the same moles of oxygen, by using its molar mass (44.02 g/mol), we obtain:

[tex]m_{CO_2}=3molCO_2*\frac{44.01gCO_2}{1molCO_2} =132.03gCO_2[/tex]

iii. Now, we need to combine the previously used two proportional factors for the calculation of the mass of CO2 from 128.00 grams of oxygen (molar mass 32.00 g/mol):

[tex]m_{CO_2}=128.00gO_2*\frac{1molO_2}{32.00gCO_2}*\frac{3molCO_2}{5molO_2}*\frac{44.01gCO_2}{1molCO_2}\\\\m_{CO_2}=105.6gCO_2[/tex]

Just took the quiz

Answer:

8.87 L.

Explanation:

From the question given above, the following data were obtained:

Mass (m) of gas = 12 g

Initial volume (V₁) = 14.5 L

Initial pressure (P₁) = 52 cmHg

Final pressure (P₂) = 85 cmHg

Final volume (V₂) =?

The final volume of the gas can be obtained by using the Boyle's Las equation as illustrated below:

P₁V₁ = P₂V₂

52 × 14.5 = 85 × V₂

754 = 85 × V₂

Divide both side by 85

V₂ = 754 / 85

V₂ = 8.87 L

Thus the volume of the gas will be 8.87 L
