can some vitamins be considered water-soluble and others fat soluble?​

Answers

Answer 1

Answer:

Vitamins are classified as either fat soluble (vitamins A, D, E and K) or water soluble (vitamins B and C). This difference between the two groups is very important. It determines how each vitamin acts within the body.

A mixture of 0.384 M H2O, 0.384 M Cl2O, and 0.652 M HClO are placed in a vessel at 25 oC. Calculate the equilibrium concentration (in molarity) of HClO at the same temperature.

Answers

Equilibrium concentration of HOCl at 25°C is 0.140 M

The equation of the reaction at equilibrium is given below:

H₂O (g) + Cl₂O (g) ⇄ 2 HOCl (g)

Equilibrium constant, Kc = 0.0900 at 25°C

An ICE chart for the reaction is set up below

     H₂O (g)  +  Cl₂O (g)   ⇄  2 HOCl (g)

I     0.384        0.384             0.652

C     -x                -x                   + 2x

E    0.384 - x   0.384 - x       0.652 + 2x

The equation of the equilibrium constant is given as;

Kc = [tex]\frac{[HOCl]^2}{[H_{2}O][Cl_{2}O]}[/tex]

substituting the values into the equation:

Kc = [tex]\frac{(0.652 + 2x)^2}{( 0.384 - x)( 0.384 - x)}[/tex] = 0.0900

4x² + 2.608x + 0.425 = 0.0900 (0.147 - 0.768x + x²)

4x² - 0.09x² + 2.677x - 0.069x + 0.425 - 0.013 = 0

3.910x² + 2.677x + 0.412 = 0

Solving using the quadratic formula:

a = 3.910, b = 2.677, c = 0.412

x = [tex]\frac{-2.677\±\sqrt{2.677^2 - 4*3.910*0.412}}{2*3.910}[/tex]

x = -0.256 or -0.431

The negative sign indicates that equilibrium is to the left of the reaction

Since x cannot be greater than 0.384, x = -0.256.

Equilibrium concentration of HOCl = 0.652 + 2(-0.256)

Equilibrium concentration of HOCl at 25°C is 0.140 M

How are the sensory clues from watching a fire different from the sensory clues from watching a firefly?​

Answers

Answer:

sensory experience of a chemical reaction called combustion. In a way, fire is like the leaves changing color in fall, the smell of fruit as it ripens, or a firefly's blinking light. All of these are sensory clues that a chemical reaction is taking place

Explanation:

Sensory encounter with the combustion chemical process. Fire can be compared to the fall foliage's shifting hues, the aroma of ripe fruit, or the blinking light of fireflies. These are all sensory indicators that a chemical reaction is occurring.

What is combustion?

Combustion is defined as a chemical interaction between different compounds, usually involving oxygen, that produces heat and light in the form of flames. Hydrocarbons and oxygen are the only reactants in a combustion reaction. The fuel is a hydrocarbon, and oxygen is required for burning.

It stimulates several of our senses at once, producing the vivid experience we anticipate from a tangible object. By using fuel, heat, and oxygen during combustion, that sensory experience is produced.

Thus, sensory encounter with the combustion chemical process. Fire can be compared to the fall foliage's shifting hues, the aroma of ripe fruit, or the blinking light of fireflies. These are all sensory indicators that a chemical reaction is occurring.

Answers

The effect of a catalyst is

Option B(lower the activation energy of a reaction whereby making it easier for the reactants to get over the energy hump)What is a catalyst

A catalyst allows an alternative reaction pathway that leaves activation energy than the uncatalysed reaction. This does not change the frequency of collision.

Frequency of collision

Frequency of collision depend upon concentration of reactant temperatures

Catalyst on activation energy

Hence, catalyst lowers the activation energy of reaction thereby making it easier for the reactant to get over the energy hump.

Answer:

c.boron-11

Explanation:

The atomic mass of boron is 10.81 u.

And 10.81 u is a lot closer to 11u than it is to 10u, so there must be more of boron-11.

To convince you fully, we can also do a simple calculation to find the exact proportion of boron-11 using the following formula:

(10u)(x)+(11u)(1−x)100%=10.81u

Where u is the unit for atomic mass and x is the proportion of boron-10 out of the total boron abundance which is 100%.

Solving for x we get:

11u−ux=10.81u

0.19u=ux

x=0.19

1−x=0.81

And thus the abundance of boron-11 is roughly 81%.

Why must labs that use mercury thermometers calculate Kelvin ? ​

Answers

Answer:

because those are the only thermometers that are truly accurate for kelvins

Explanation:

The Kelvin temperature in thermometers is used by scientists because it provides a temperature where zero indicates the complete absence of thermal energy.

What is the Kelvin scale?

All thermometers have a scale on them that we use to find the temperature, known as a temperature scale. Kelvin proposed that the temperature interval from the ice point to the steam point be defined as 100° containing earlier centigrade scales.

Lord Kelvin had given an absolute temperature scale based on the Carnot cycle.  The zero point is 273.15 on Kelvin’s scale below that of the Celsius scale.

On the kelvin scale, Each division is called a Kelvin (K) and is equal to a degree on the Celsius scale. On the Celsius scale, zero degrees is the freezing point of water while on the Kelvin scale the zero point is at absolute zero temperature.

Therefore, 0 K is equal to - 273.15°C, and 0°C is equal to 273.15 kelvins. A mathematical expression that gives the relation between the Celsius and Kelvin scales:

Temperature (K) = Temperature (°C) + 273

4. Increase of resistance in metals. Therefore the mobility of electrons decreases and causes decrease in conductivity.
5.To increase strength, increase corrosion resistance, or reduce costs.
6. All metals have low ionization energies and are relatively electropositive, and so they lose electrons fairly easily.
