what is the ph of a buffer in which the concentration of benzoic acid, c6h5cooh, is 0.075 m and the concentration of sodium benzoate, nac6h5coo, is 0.050 m ?

Answers

Answer 1

The answer is 4.02.

Benzoic acid is a weak acid and sodium hydroxide is a strong base. Benzoic acid and sodium hydroxide react to form sodium acetate and water to form a buffer solution. pH can be measured by measuring the voltage developed between two special electrodes immersed in a liquid solution.

Special glass electrodes are called measuring electrodes. It neutralizes benzoic acid to produce benzoate ions, which enter the water layer, leaving two other organic compounds in the ether. Similarly, nitroaniline does not dissolve under neutral or basic conditions but dissolves in acidic solutions. This clearly shows that formic acid is a stronger acid than benzoic acid.

molecular hydrogen effuses 4.0 times as fast as gas x at the same temperature. what is the molar mass of gas x?

Answers

The molar mass of gas x is 2.0g/mol.

Solution:

Molecular hydrogen effuses four times as fast as gas x at the same temperature

Oxygen is diatomic (O2)

Oxygen's molar mass = 32.0 g/mol.

Certain Gas = fast/light and Oxygen = slow/heavy

Set rate expression equal to the molar mass expression

[tex]\frac{4}{1}[/tex] = [tex]\sqrt{\frac{32}{x} }[/tex]

X = 2.0g/mol

Moles do not change with temperature because temperature affects volume, not mass. When a liquid or gas is heated, the molecules move faster, collide and spread. Since the molecules are distributed, they occupy more space. they are less dense. The opposite happens when a liquid or gas cools.

As the kinetic energy of the molecules in the gas increases, an increase in temperature causes the gas to expand, thus increasing in volume. When the same number of gas molecules occupy more volume, the density of air decreases. Volume is simply defined as the amount of space occupied by a three-dimensional solid.

Which object will have the smallest change in motion when an equal force is applied?



8 kg circle

Answers

The object will have the smallest change in motion when an equal force is applied is 8kg circle.

What is force?

A force is described as an influence that can change the motion of an object.

A force can cause an object with mass to change its velocity or to change its acceleration. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

The object will have the smallest change in motion when an equal force is applied is 8kg circle because according to Newton's second law which states that the rate of change of momentum of an object is directly proportional to the net force acting on it, provided that the mass of the body is kept constant.

This means that  as mass increases, force will increase. However, if acceleration is negative, then force will just increase by the same amount in the opposite direction.

If the ionic constant Q is greater than Ksp the solution forms precipitate if it is lower than the solubility constant Ksp then there will be no precipitate. Both of the given solutions forms precipitate.

What is ionic constant?

The ionic constant Q of a solution is the product of molar concentrations of reactants. Solubility constant Ksp is the product of solubilities of the reactant ions when the reaction is in equilibrium.

For the first solution Q = 0.020 M × 0.015M  = 0.003.

Ksp  = 0.000001. Hence, Q is greater than Ksp which means the solution forms precipitate of BaF₂.

The three rules that direct the manner in which electrons are to be filled in atomic orbitals are:

Aufbau principle: Electrons must completely fill the atomic orbitals of a given energy level before occupying an orbital of a higher energy level. Electrons fill orbitals in the increasing order of orbital energy level.

Pauli’s exclusion principle: It states that two electrons can never have equal values for all four quantum numbers. Also each subshell of an orbital can have a maximum of 2 electrons and both these electrons must have opposite spins.

Hund’s rule of maximum multiplicity: The subshells in an orbital must be singly occupied before it is doubly occupied. Furthermore, the spin of all the electrons in singly occupied subshells should be the same (to maximize the overall spin).

what is the volume (in l) of a scuba tank if it takes 2000l of air collected at 1.00 atm to fill the tank to a pressure of 150 atm? assume n and t are constant

Answers

The volume of the air collected at the pressure of 150 atm is 13.33 litres.

The pressure P, the volume V, the number of moles n, the gas constant R and the temperature t of the gas are related with each other as,

PV = nRT

If the number of moles and the temperature are constant,

PV = Constant

So, we can write,

P₁V₁ = P₂V₂

P₁ is the pressure of the scuba tank is 1 atm and the volume V₁ of the scuba tank is 2000L while P₂ is pressure of the other tank is 150 atm. Hence we can write,

2000 x 1 = V₂ x 150

Answers

A man is sitting on a chair and exerting 100 N of force downward, while a spring beneath the chair exerts 150 N of force upward. The net force acting on the system is in the upward direction with a magnitude of 50N.

Force is the product of mass and acceleration which is dependent on the rate of change of momentum.

According to the given question,

Magnitude of force in the downward direction = 100N

Downward force = 100N

Magnitude of force in the upward direction = 150N

Upward force = -150N

Net force on the system = Upward force + Downward force

Net force on the system = -150N + 100N

Net force on the system = -50N

hydrocarbons are compounds that contain only carbon and hydrogen. combustion of a sample of a particular hydrocarbon gave 5.86 g of co2 and 1.37 g of h2o. what is the empirical formula of the hydrocarbon?

Answers

the emperical formula of the  hydrocarbons was CH

what is emperical formula?

The simplest whole number ratio of atoms contained in a substance is its empirical formula in chemistry. The empirical formula of sulphur monoxide, abbreviated SO, and disulfur dioxide, abbreviated S2O2, are two straightforward examples of this idea. As a result, the empirical formula for sulphur monoxide and disulfur dioxide, two compounds made of sulphur and oxygen, is the same. Their molecular formulae, which represent how many atoms are present in each molecule of a chemical compound, are different.

It's important to remember that you're dealing with a hydrocarbon in this situation, which is a chemical made up solely of carbon and hydrogen.

As you can see, the byproducts of this combustion reaction are carbon dioxide, CO2, and water, H2O.

As a result, all the carbon that was formerly a component of the hydrocarbon will now be a component of the carbon dioxide. Similar to how all of the hydrogen that originally made up the hydrocarbon is now a component of the water.

This means that you can calculate the initial amounts of carbon and hydrogen in the hydrocarbon by counting the moles of water and carbon dioxide, respectively.

So, for water you have

1.37g x 1mole H2o/18.015 =0.076moles H2o

and for carbon dioxide

5.86g x 1 mole CO2/44.01g=0.133 moles CO2

Now, you know that every mole of water contains 2 moles of hydrogen and 1 mole of oxygen, which means that the reaction produced

0.076moles H2O x 2 moles H1/mole H2O=0.152 moles H

SInce every mole of carbon dioxide contains 1 mole of carbon and 2 moles of oxygen, it follows that the reaction also produced

0.133moles CO2 x 1 mole C/1mole CO2=0.133 moles C

Finally, to find the mole ratio that exists between carbon and hydrogen in the hydrocarbon, divide these values by the smallest one

For C: 0.133moles/0.133moles=1

For H: 0.152moles0.133moles=1.14≈1

The empirical formula of the hydrocarbon will thus be

In the process of chromatography, the components of the sample are divided according to how evenly they disperse between a stationary phase and a mobile phase. Using using a variable rate of migration in an electric field, sample components are separated by electrophoresis.

The foundation of chromatography is the idea that mixtures of molecules applied to surfaces or solids, and fluid stationary phases (stable phases), separate from one another while moving with the help of a mobile phase.

The fundamental idea behind column chromatography is to use a stationary phase to help adsorb the solution's solutes before further separating the mixture into distinct components.

In gel electrophoresis the separation is by charge is to mass ratio and hence smaller molecules moves faster then larger molecules.
