Percentage of the enantiomers in solution are compound A = 78.27%

B rotates +12.5 degrees then A rotates -12.5 degrees

Enantiomeric excess = Specific rotation of mixture / specific rotation of pure enantiomer * 100

EE = -3.6/-12.6*100 = 28.57 %

percentage of A = 50 + 28.57 = 78.27 %

Enantiomers are a pair of molecules that can never be superimposed one on top of the other despite existing in two mirror images of one another. Enantiomers are chemically similar to one other in all other respects. The phrase "optical isomers" refers to a pair of enantiomers that can be identified by the direction in which, when dissolved in solution, they rotate polarized light, either dextro (d or +) or levo (l or -). A racemic combination is one that does not spin polarized light when two enantiomers are present in equal amounts because the optical activity of each enantiomer is cancelled out by the other.

The balanced chemical equation for the combustion of C3H8 is:

C3H8 + 5O2 → 3CO2 + 4H2O

According to the equation, for every 1 mole of C3H8 that is burned, 3 moles of CO2 are produced.

Therefore, to find the number of moles of CO2 produced from the combustion of 6.4 mol of C3H8, we can use the mole ratio from the balanced equation:

6.4 mol C3H8 × (3 mol CO2 / 1 mol C3H8) = 19.2 mol CO2

So, 19.2 moles of CO2 are produced from the combustion of 6.4 mol of C3H8.

The average atomic mass of the given element is 6.877 atomic mass units (amu).

We have been given the following data about the isotopes of the element:

Mass of first isotope, m₁ = 6.015 amu

Abundance of first isotope, a₁ = 7.59% or 0.0759

Mass of second isotope, m₂ = 7.016 amu

Abundance of second isotope, a₂ = 92.41% or 0.9241

Using the formula for average atomic mass of an element, we have:

average atomic mass = (m₁ × a₁) + (m₂ × a₂)

average atomic mass = (6.015 amu × 0.0759) + (7.016 amu × 0.9241)

average atomic mass = 0.4562 amu + 6.4665 amu

average atomic mass = 6.9227 amu

Rounding off to the nearest hundredth, we get:

average atomic mass ≈ 6.88 amu

Therefore, the average atomic mass of the given element is 6.877 atomic mass units (amu).

Answer:

The polar water molecules exert strong cohesive forces on one another

Explanation:

The forces of cohesion refer to the strong attractive forces that molecules of a substance exert on each other.

This strong attractive force keeps the molecules of the water together and causes the water molecules to be pulled inside towards each other. We refer to this phenomenon as surface tension.

Hence, due to surface tension, water does not run off an inclined plane.

The Earth's surface is not covered with the same materials ; however, some areas share similar materials.Several drilling sites have been dug in various regions of the planet to analyze the Earth's surface.

Each drilling site is unique, with differing characteristics and results. Despite these differences, all of the drilling sites analyzed offer scientists a more in-depth knowledge of the Earth's surface.In essence, the scientific drilling sites each had different lithologies, stratigraphies, and geologies. Each site had different types of rocks, depths, and ages, which led to varying drilling conditions, depths, and equipment used. Different types of equipment were also used to reach the depths required, which was a significant difference in each drilling site.The scientific drilling sites also had different purposes. Scientists had specific goals they wanted to achieve at each location. For example, the scientific drilling site in the Iceland region was focused on analyzing a unique layer of igneous rocks. The primary objective was to investigate the formation of the rock layer.The same materials were not found at each scientific drilling site.

Still, they had some similarities. They all provided geologists with vital information about the Earth's surface. The data provided from each drilling site was used to piece together the Earth's geologic history and how it has changed over time.

Explanation:

Using significant figures 0.00296 moles of helium can be calculated to be contained in the balloon.

You might have learnt in school that at STP (Standard Temperature and Pressure), the temperature is 273.15 K and the pressure is 1 atm. The molar volume of any given gas at STP will always be 22.4 L/mol. This will perhaps be known to you as Avogadro's Law.

You are having 75.000 mL of helium, which is 0.075 L. To find the number of moles of helium, you will make use of the ideal gas law:

PV = nRT

The notations are commonly known as P for pressure, V for volume, n is for number of moles, R for gas constant, and T for temperature in Kelvin scale.

At STP, P = 1 atm and T = 273.15 K. The gas constant R is 0.08206 L·atm/mol·K.

So you will then have:

n = PV/RT = (1 atm)(0.075000 L)/(0.08206 L·atm/mol·K)(273.15 K)

n = 0.00296 mol

Using significant figures, you can then round this to three significant figures:

n = 0.00296 mol

The numbre of moles is 0.00296. This is your final answer.

The wind tends to flow parallel to the isobars above the friction level due to the balance between the pressure gradient force and the Coriolis force.

The pressure gradient force is responsible for the wind's movement from areas of high pressure to areas of low pressure. Isobars are lines connecting points of equal pressure on a weather map. The closer the isobars are to each other, the steeper the pressure gradient and the stronger the pressure gradient force.

The Coriolis force is an apparent force resulting from the Earth's rotation. It deflects the wind to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. The Coriolis force increases with increasing wind speed.

Above the friction level, where the influence of surface roughness is minimal, the pressure gradient force and the Coriolis force are the primary factors determining wind direction. The wind tends to flow parallel to the isobars because the pressure gradient force is balanced by the Coriolis force. This balance results in a geostrophic wind flow, which is characterized by winds moving parallel to the isobars at a constant speed.

In conclusion, above the friction level, the wind flows parallel to the isobars due to the balance between the pressure gradient force and the Coriolis force. This geostrophic wind flow pattern is observed in the upper levels of the atmosphere where the influence of surface friction is minimal.

To calculate the average growth rate for Adidas during the four-year period, we need to find the arithmetic mean of the individual growth rates. Here are the steps:

1. Sum up the growth rates for each year:

  Sum = 0.5196 + 0.0213 + 0.0485 + (-0.0387)

2. Divide the sum by the total number of years (4 in this case):

  Average Growth Rate = Sum / 4

By evaluating this expression, you can find the average growth rate for Adidas during the four-year period.

Total growth rate = 0.5196 + 0.0213 + 0.0485 - 0.0387 = 0.5507

Average growth rate = Total growth rate / Number of years = 0.5507 / 4 = 0.1377
