Peter Goemans  is the founder of Blue Bell .

Blue Bell was established in 1907 as a means of utilising extra cream from nearby dairy producers. Brenham Creamery Company, the predecessor to the business that is today known as Blue Bell, was founded in 1907. The men who founded it thought the name made sense because it was in the sleepy Texas town of Brenham.

Blue Bell may soon resume selling ice cream after a widespread recall forced the company to lay off 1,500 workers in May. Following a widespread product recall this past spring, Sid Bass, a Fort Worth oil millionaire, has now accepted a "substantial investment" from the Brenham, Texas-based ice cream firm Blue Bell.

In evolution, isolation means one group is separated and isolated from a population to study the adaption of evolutionary changes over a period of time.

A natural phenomenon called evolution describes how inheritable traits of a species alter through time.

Natural selection, mutation, genetic drift, and migration are the key drivers. Geographical or reproductive isolation stop the exchange of genetic material across populations. As a consequence of adaptation to a particular environment or niche throughout time, populations of many species changed (natural selection).

When there is a barrier that the creatures can't overcome, they become isolated, which implies they are separated from other members of their species. The isolation of organisms is a consequence of environmental change. When mountain ranges or deserts emerge or when continents separate, isolation may develop gradually.

Reaction will not occur in first case and will occur in second case.

A. When Copper is mixed with HCl

When Copper and hydrochloric acid are mixed no reaction takes place because Cu is present below hydrogen. Diluted acids do not react with metals below hydrogen because they cannot replace hydrogen in diluted acid and are less reactive than hydrogen.

B. Sodium trioxocarbonate (IV) and trioxocarbonate acid (IV)-

When sodium trioxocarbonate (IV) and trioxocarbonate acid (IV) are mixed Sodium bicarbonate is formed.

A salt called sodium bicarbonate also called as baking soda  decomposes in water to produce sodium and bicarbonate. A solution becomes alkaline as a result, making it capable of neutralizing acid.

When boiling, the total mass of liquid and vaporized water stays the same.

The law of conservation of mass states that the mass can neither be created nor destroyed but is transformed from one form to another.

The law helps us to understand the conversion of energy from one form to another.

For example in a torch, the chemical energy of the batteries is converted into electrical energy, which is converted into light and heat energy.

Based on the law of conservation of mass, the total mass of of liquid and vaporized water during boiling will be constant.

Boron is in group 3 so it has 3 valence electrons.

Carbon is in group 4 so it has 4 valence electrons.

Taking into account the definition of wavelength, frecuency and propagation speed, the frequency of radiation whose wavelength is 0.81 nm is 3.48×10¹⁷ Hz.

Wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. It is expressed in units of length (m).

Frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).

The propagation speed measures the speed at which the wave disturbance propagates along its displacement.

The propagation speed relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation:

v = f× λ

All electromagnetic waves propagate in a vacuum at a constant speed of  the speed of light.

In this case, you know:

Replacing in the definition of propagation speed:

3×10⁸ m/s= f× 0.86×10⁻⁹ m

Solving:

3×10⁸ m/s÷ 0.86×10⁻⁹ m= f

3.48×10¹⁷ Hz= f

In summary, the frequency of radiation whose wavelength is 0.81 nm is 3.48×10¹⁷ Hz.

The new rate constant is 1.5 * 10^6  M-1s-1 .

In this case we know that we have to use the Arrhenius equation to find the rate constant at two different temperatures by the use of the formula;

ln(k2/k1) = -Ea/R(1/T2 - 1/T1)

k2 = Rate constant at  436 K

k1 = Rate constant at 249 K

T1 = initial temperature

T2  = final temperature

R = Gas constant

Ea = activation energy

Hence;

ln(k2/1.60 × 10^2) = -38 * 10^3/8.314(1/436 - 1/249)

ln(k2/1.60 × 10^2) =  -38 * 10^3/8.314(0.002 - 0.004)

ln(k2/1.60 × 10^2) =  9.14

k2/1.60 × 10^2 = e^ 9.14

66.3% is the percent yield for the reaction PCl3(g) + Cl2(g) -> PCl5(g).

The correct option is E.

The % ratio of the theoretical yield to the actual yield is known as the percent yield. It is calculated as the theoretical yield multiplied by 100% divided by the experimental yield. The percent yield is 100% if the theoretical and actual yields are equal.

A greater yield percentage may be an indication that your product is tainted with water, too much reactant, or other impurities. A lower yield percentage could mean that you miscalculated a reactant or spilled some of your product.

Divide the theoretical yield by the experimental yield. Calculate the percent yield by multiplying this figure by 100.

Answer:

low density -> high temperature -> increased particle motion -> high kinetic energy -> high thermal energy -> greater thermal expansion -> more contraction

Explanation:

To model the relationship between these factors, you need to understand how they interact. A greater density of particles usually means they are moving slower, thus resulting in less energy and less heat consequentially. As temperature increases, particles will begin to move rapidly (increase motion) and have higher kinetic energy. Similarly, a lower temperature will lead to less motion and lower kinetic energy. Furthermore, their thermal expansion will be less and have a decrease in contraction, as they will be more compact and dense.

Therefore you could make a model such as:

low density -> high temperature -> increased particle motion -> high kinetic energy -> high thermal energy -> greater thermal expansion -> more contraction

The mass of the solid is calculated to be 118.28g.

The mass of a substance can be calculated using the following formula:

Density = mass ÷ volume

According to this question, a liquid solvent is added to a flask containing an insoluble solid. The total volume of the solid and liquid together is 77.0 mL. The liquid solvent has a mass of 29.4 g and a density of 0.865 g/mL.

First, we calculate the volume of the liquid as follows:

0.865 = 29.4/volume

volume = 29.4/0.865

volume of the liquid solvent = 33.99mL

Volume of the solid = 77.0mL - 33.99mL = 43.01mL

Mass of the solid = 43.01mL × 2.75 g/mL

Mass of the solid = 118.28g
