It take 38.70cm³ of 1.90 NaO4 to neutralize 10.30cm³ of H2So4 in a battery. Calculate the molar concentration of H2So4

Answers

Answer:

The molar concentration of base Cb = 14.2777M

Explanation:

Volume of acid Va = 38.70cm^3,

Concentration of acid NaO4 C_a= 1.90M

Volume of Base Vb = 10.30cm^3

Also, Equation of the reaction

H2SO4 + 2NaOH = Na2SO4 + 2H2O

No of mole of acid Na = 1

No of mole of base Nb = 2

CaVa/CbVb = Na/Nb

Cb = CaVaNb/VbNa

Cb = 1.9×38.7×2/(10.30×1)

Therefore, Cb = 14.2777M

The molar concentration of base Cb = 14.2777M

Personal connection is a connection with your own self to something

Answer:

Explanation:

When we say anything is a wave, what exactly do we mean? The most intuitive and straightforward wave to envision is a water wave. A motion, more specifically, is a disturbance that propagates or travels away from its source. Water waves are caused by a disruption in the water's surface, such as a rock tossed into a pond or a swimmer splashing the surface continuously. The noise for sound waves is a rise of air pressure, which may be caused by the oscillating cone within a speaker. There are many kinds of disturbances in earthquakes, including surface disturbances and pressure disturbances under the surface. Even radio signals are best deciphered by using a comparison of sea waves Water waves are helpful to visualize since they are more than just a mental picture. The amplitude, period, frequency, and energy of water waves are all the same as they are for all waves. A small set of underlying principles can be used to describe all wave characteristics.

⦁ Find the concentration of H+, OH-, PH and POH of 0.03 M of magnesium hydroxide which ionizes to the extent of only 1 /3 in aqueous solution.

Answers

Answer:

[tex]pH=12.3\\\\pOH=1.7\\[/tex]

[tex][H^+]=5x10^{-13}M[/tex]

[tex][OH^-]=0.02M[/tex]

Explanation:

Hello there!

In this case, according to the given ionization of magnesium hydroxide, it is possible for us to set up the following reaction:

[tex]Mg(OH)_2(s)\rightleftharpoons Mg^{2+}(aq)+2OH^-(aq)[/tex]

Thus, since the ionization occurs at an extent of 1/3, we can set  up the following relationship:

[tex]\frac{1}{3} =\frac{x}{[Mg(OH)_2]}[/tex]

Thus, x for this problem is:

[tex]x=\frac{[Mg(OH)_2]}{3}=\frac{0.03M}{3}\\\\x= 0.01M[/tex]

Now, according to an ICE table, we have that:

[tex][OH^-]=2x=2*0.01M=0.02M[/tex]

Therefore, we can calculate the H^+, pH and pOH now:

[tex][H^+]=\frac{1x10^{-14}}{0.02}=5x10^{-13}M[/tex]

[tex]pH=-log(5x10^{-13})=12.3\\\\pOH=14-pH=14-12.3=1.7[/tex]

3. Which of the following is the correct mathematical expression to use to
calculate the pH of a 0.10 Maqueous Ba(OH)2 solution at 25°C ?

Answers

Answer:

The pH of a 0.10 Maqueous Ba(OH)2 solution at 25°C is 13.30

Explanation:

The balanced equation is Ba(OH)2(s)→Ba2++2OH−

This indicates that the concentration is 0.2 M

We will find H+ ion concentration

As we know that

[H+][OH−]=1.0×10−14M

Given -  

[OH−]=2.0×10−1M

Putting value of [OH-] in above equation we get -  

[H+]=5.0×10−14M

pH=−log10[H+]

pH=−log10[5.0×10−14] = 13.30.

P4O10 + 6H20 → 4H3PO4

If 30 g of H2O reacts with 40g of P4O10, what is the limiting reactant? How much H3PO4 can be formed?

Answers

Answer:  [tex]P_4O_{10}[/tex] is the limiting reagent

66.6 g of [tex]H_3PO_4[/tex] will be formed.

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]  [tex]\text{Moles of} P_4O_{10}=\frac{40g}{284g/mol}=0.14moles[/tex]

[tex]\text{Moles of} H_2O=\frac{30g}{18g/mol}=1.7moles[/tex]

[tex]P_4O_{10}+6H_2O\rightarrow 4H_3PO_4[/tex]  

According to stoichiometry :

1 mole of [tex]P_4O_{10}[/tex] require 6 moles of [tex]H_2O[/tex]

Thus 0.14 moles of [tex]P_4O_{10}[/tex] will require=[tex]\frac{6}{1}\times 0.14=0.84moles[/tex]  of [tex]H_2O[/tex]

Thus [tex]P_4O_{10}[/tex] is the limiting reagent as it limits the formation of product and [tex]H_2O[/tex] is the excess reagent.

As 1 mole of [tex]P_4O_{10}[/tex] give = 4 moles of [tex]H_3PO_4[/tex]

Thus 0.17 moles of [tex]P_4O_{10}[/tex] give =[tex]\frac{4}{1}\times 0.17=0.68moles[/tex]  of [tex]H_3PO_4[/tex]

Mass of [tex]H_3PO_4=moles\times {\text {Molar mass}}=0.68moles\times 98g/mol=66.6g[/tex]

Thus 66.6 g of [tex]H_3PO_4[/tex] will be formed.

If 0.583 g of ammonia (NH3) is dissolved to make 250 mL of solution, what is the molarity?

Answers

Answer:

0.137 M NH3

Explanation:

First divide the mass of NH3 by the molar mass of NH3, and then divide by the volume to get molarity.

0.583 g / 17.031 g/mol = 0.0342 mol NH3

0.0342 mol NH3 / 0.250 L = 0.137 M NH3

Change in entropy
Heat of reaction
Activation energy
Reaction complex

Answers

Answer: Heat of reaction

Explanation:

Change in entropy is the difference between the entropy of products and the entropy of reactants.

 Heat of reaction is the energy released or absorbed during the course of the reaction. It is difference between the potential energy of the products and the potential energy of the reactants.

Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.

Reaction complex is the short lived intermediate formed when reactants are coverted to products.

350.0 ML of air is at 23.0°C what is the volume at 90.0°C

Answers

Answer:

V=0.430 Liters

Explanation:

First off you need to convert ml to l and celsius to kelvin, in order for them to be in the S.I.

So, 350.0mL is 0.350 L and 23.0 C is (273.15+23=) 296.15 K (you can ignore the 0.15)

From the equation pV=nRT, lets name this equation (1),  we can tell that the number of moles, pressure, and R, stay the same. The only thing changing is the volume, and temperature.

With the information given, let's figure out the pressure. From equation (1) if we solve it for the pressure of the gas, p=nRT/V => p=nR*296.15/0.350 => p=846.15 *nR

Now, we have to figure out the volume of the gas at 90.0 C (363.15 K), and solve equation (1) for volume, using the pressure we previously found.

v=nRT/p => v=nR*363.15/846.15*nR => (the nR's from top and bottom go away) v=0.429 L

Since we used 273.15 for the conversion of celsius to Kelvin, we could round up the number to

V=0.430 Liters

6. The substance whose Lewis structure shows triple covalent bonds is
a. Hydrogen dioxide
b. Nitrogen trihydride
c. Carbon monoxide
d. Carbon tetrachloride

Answers

Answer: b) Nitrogen trihydride should be the answer.

Explanation:

Nitrogen trihydride is the substance whose Lewis structure shows triple covalent bonds. Hence option is correct.

What are covalent bonds?

Covalent bonds are defined as the shared electron pair between two atoms that creates an interatomic bond. At room temperature, covalent compounds can be found in all three of their physical states and often have low boiling and melting temperatures. Covalent substances don't carry electricity.

Lewis structure are defined as a structural depiction of a molecule using lines or pairs of dots to represent covalent bonds between atoms and dots to show the locations of electrons surrounding the atoms. The goal of creating a Lewis dot structure is to locate lone electron pairs in molecules in order to better understand how chemical bonds are formed. In chemistry, a triple bond is a covalent connection where two atoms share three pairs of electrons, such as in the nitrogen molecule (N2) or the acetylene molecule (C2H2).

Thus, Nitrogen trihydride is the substance whose Lewis structure shows triple covalent bonds. Hence option is correct.
