In industrial settings, soaps are used as thickeners, components of some lubricants, and precursors to catalysts

The coriolis effect is responsible for many large scale weather patterns. The coriolis force is responsible for the deflection of objects. It is this effect which drive the global wind and ocean circulation patterns. The correct option is C.

The apparent effect produced by a rotating frame of reference is defined as the coriolis effect. This effect occurs when an object moving along a straight path is viewed from a non-fixed frame of reference.

Because of the earth's rotation, when an object moving in a straight path is viewed from earth, it appears to lose its course. So the travelling long distances around the earth appear to move at a curve instead of a straight line due to coriolis effect.

The coriolis effect is found to be strongest near poles and it is absent at the equator. The coriolis force is an apparent force caused by the rotation of earth.

Thus the correct option is C.

Answer: The percent dissociation of butanoic acid is 9.8%

Explanation:

[tex]C_3H_2CO_2H\rightarrow H^+C_3H_2CO_2^-[/tex]

 cM                                                0             0

[tex]c-c\alpha[/tex]               [tex]c\alpha[/tex]          [tex]c\alpha[/tex]  

So dissociation constant will be:

[tex]K_a=\frac{(c\alpha)^{2}}{c-c\alpha}[/tex]

Give c= 1.4 mM = [tex]1.4\times 10^{-3}[/tex] and [tex]\alpha[/tex] = dissociation constant  

[tex]K_a=1.5\times 10^{-5}[/tex]

Putting in the values we get:

[tex]1.5\times 10^{-5}=\frac{(1.4\times 10^{-3}\times \alpha)^2}{(1.4\times 10^{-3}-1.4\times 10^{-3}\times \alpha)}[/tex]

[tex](\alpha)=0.098=9.8\%[/tex]

Thus percent dissociation of butanoic acid is 9.8%

Answer:

10/24

Simplified: 5/12

Explanation:

Well first, let's convert years into months

1 year = 12 months which means 2 years = 24 months

In fraction form we would write this as 10/24

If the question asks for it to be simplified, then simply

Both 10 and 24 evenly fit 2

Therefore, divide both the numerator and the denominator by 2

10 ÷ 2 / 24 ÷ 2

5/12

This can no longer be simplified

The order of marbles can be Aluminum, Nickel, Silver, and Rhenium.

If volume is the amount of three-dimensional space contained by a closed surface, such as the amount of space within a given cube, cylinder, or other three-dimensional shape.

Liquid volume is a way to measure an amount of liquid by describing how much three-dimensional space it occupies.

The mass of something is the amount of stuff it is made of. The volume of an object is the amount of space it usually takes up.

Density provides an easy way to calculate a body's mass from its volume or vice versa.

The mass is equal to the volume multiplied by the density (M = Vd), and the volume is equal to the mass divided by the density (V = M/d).

As per the density given, the volume of aluminum can be 1.11mL, Silver is 0.286mL, Rhenium is 0.144mL, Nickel is 0.337mL.

Thus, the order from largest to smallest will be Aluminum, Nickel, Silver, and Rhenium.

Answer:

17.54 g

Explanation:

the freezing point of the solution to -8.8°C

depression in freezing point = 8.8°C

Molal freezing point depression constant of ethylene glycol  Kf = 3.11⁰C /m

ΔTf = Kf x m , m is no of moles of solute per kg of solvent .

Let gram of ethylene glycol required be x .

moles = m / mol weight of ethylene glycol

= x / 62

100 g of water = .1 kg

moles of solute dissolved in 1 kg of water

m = x / 62 x .1

m = 10 x / 62

Using the above equation for depression in freezing point

8.8 = 3.11 x 10 x / 62

x = 17.54 g .

The mass of ethylene glycol required to lower the freezing point is 17.54 g.

The given parameters:

Molar freezing point depression constant of ethylene glycol  Kf = 3.11⁰C /m

Let the mass of ethylene glycol required be x .

The number of moles of the ethylene is calculated as follows;

[tex]n = \frac{x}{M} \\\\n = \frac{x}{62 \times 100 g \ of H_2 O}\\\\n = \frac{x}{6.2}[/tex]

Apply the following equation for depression in freezing point as follows;

[tex]\Delta T_f = n Kf\\\\8.8 = 3.11 \times \frac{x}{6.2} \\\\3.11 x = 54.56\\\\x = \frac{54.56}{3.11} \\\\x = 17.54 \ g[/tex]

Thus, the mass of ethylene glycol required to lower the freezing point is 17.54 g.

Oxygen and sulphur are in the same family with the same number of valence electrons.

The electrons in an atom's outermost shell, or energy level, are called valence electrons.

Compared to oxygen, sulphur has more electron shells. This is because sulphur has three electron shells because it is in period 3 of the periodic table, whereas oxygen is in period 2 and has two electron shells.

Since there is just one link between these oxygen atoms, they will each have six valence electrons and a shared valence electron with sulphur.

Electromagnetic radiation is the energy waves with various wavelengths. Ultraviolet rays have the shortest wavelength. Thus, option B is correct.

A wavelength is a ratio of the velocity and the frequency as the distance between the crests is measured. The shortest wavelength haves the largest frequency.

Radio waves have the longest wavelength but the shortest frequency and similarly the gamma rays have the shortest wavelength. Ultraviolet rays come before the X-rays and the gamma rays have a short wavelength.

The specific gravity of crude oil is 0.876 as 1.00 liter of water weighs 1.00 kilograms. Then weight of crude oil is 0.876 kg.

A specific gravity is a dimensionless quantity and it is defined as the ratio of density of substance to the density of water.

It is used to determine where the object will float on the surface of liquid approximately.

As, density = mass / volume

Volume of water is 1 ml given.

So, density of substance = mass of substance

Specific gravity = density of substance / density of water

So, Specific gravity = mass of substance / density of water

Mass of substance = specific gravity x density of water

                                = 0.876 x 1.00 kg = 0.876 kg

Thus, the specific gravity of crude oil is 0.876 as 1.00 liter of water weighs 1.00 kilograms. Then weight of crude oil is 0.876 kg.
