The Elephant Maximus is the species that was introduced and later became extinct on Maguindanao.

Extinction occurs as all members of a species die, and therefore the species disappears. This includes complete extinction or extinction of the species in a specific zone.

In the case of the Elephant Maximus, which is known as the Asian Elephant, this species became extinct in a region known as Maguindanao in the Philippines.

This partial extinction occurred as the elephants from this zone were taken to Sabah in Malaysia from the 13th century to the 16th century. This occurred because the Sultans of this region considered this elephant to be a valuable and even sacred animal.

a mole of anything contains Avogadros number of 6.022X10^23  things

which has the greatest number of thing? a dozen eggs, a dozen cookies, a dozen pizzas?

a dozen is a number means 12

a mole is a number that that means 6.022 X 10^23 you calculate the molar mass from the chemical formula, but every j mole contains 6.022X10^23

Explanation:

Ionization is the process by which ions are formed by gain or loss of an electron from an atom or molecule. If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation). Energy may be lost or gained in the formation of an ion.

If the concentration of acetyl chloride  is increased ten times the rate of reaction is increased ten times.

The conversion of acetyl chloride to methyl acetate is a substitution reaction. Recall that a substitution reaction is one in which a moiety in a molecule is replaced by another.

In this reaction, the CH3O- ion replaces the chloride ion. In the first step, the CH3O- ion attacks the substrate in a slow step. This creates a tetrahedral intermediate. Loss of the chloride ion yields the  methyl acetate product.

The rate determining step is the formation of the tetrahedral intermediate. Since the reaction is first order in the acetyl chloride, if its concentration is increased ten times the rate of reaction is increased ten times.

Taking into account the definition of dilution, the concentration of the final solution is 5 mg/L.

First of all, you have to know that dilution is the reduction in concentration of a chemical in a solution.  The process consists of adding more solvent to the same amount of solute.

In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

In this case, you know:

Replacing in the definition of dilution:

25 mg/L × 10 mL= Cf × 50 mL

Solving:

Cf= (25 mg/L × 10 mL)÷ 50 mL

Cf=  5 mg/L

In summary, the concentration of the final solution is 5 mg/L.

The characteristic of reactions that depends on valence electrons is the bond type.

In chemistry, a chemical bond could be;

The type of bond formed depends on the number of valence electrons present. When there are few valence electrons on an atom, it mostly forms ionic bonds.

When there are more electrons on an atoms, it mostly forms covalent bonds and the electrons between the atoms are shared.

What is surface tension?

Explanation:

Surface tension and droplets: Surface tension is responsible for the shape of liquid droplets. Although easily deformed, droplets of water tend to be pulled into a spherical shape by the cohesive forces of the surface layer.

Surface tension forces between mucosal surfaces play an important role in the pathogenesis of the disease. The obstruction of upper airway elicit the activation of autonomic nervous system, hypoxemia, and arousal from sleep.

Aria speed during scuba diving was 0.15 m/s.

Speed is the ratio of the distance travelled to the time taken. Speed is given by:

Speed = distance / time

Given that the distance travelled was 36 meters and the time was 4 minutes, hence:

Time = 4 minutes × 60 seconds per minute = 240 seconds

Speed = 36 m / 240 s

Speed = 0.15 m/s

Therefore Aria speed during scuba diving was 0.15 m/s.

The number of moles present in 29.5 grams of argon is 0.74 mole.

The atomic mass of argon is given as;

Ar = 39.95 g/mole

The number of moles present in 29.5 grams of argon is calculated as follows;

39.95 g ------------------------------- 1 mole

29.5 g ------------------------------ ?

[tex]= \frac{29.5}{39.95} \\\\= 0.74 \ mole[/tex]

Thus, the number of moles present in 29.5 grams of argon is 0.74 mole.

The mass percent of Green Dye X in the drink powder if the molecular weight is 418.4 g/mol is 0.355%

Beer's law explains the relation between the concentration of a solution to its absorbance (A) by using the equation.

here:

Now from the calibration curve in the question, the plot between the absorbance and the concentration gives a straight line of y = mx.

Here

The equation of the calibration curve is given as:

i.e.

If the sports drink was 10 times diluted while taking the absorption measurement. Then, the actual concentration of green dye in the sports drink is:

= 0.017 mM × 10

= 0.17 mM

The number of moles of green dye in 250 mL (i.e. 0.25 L) sports drink is estimated as:

= 0.17 mmol/L × 0.25 L

= 0.0425 mmol

However, the mass of the green dye present in the sports drink is

= 0.0425 mmol ×418.4 g/mol

= 17.782 mg

Finally, the mass percent of green dye in the drink powder is:

[tex]\mathbf{ = \dfrac{mass (dye)}{mass (powder)} \times 100\%}[/tex]

[tex]\mathbf{ = \dfrac{17.782 \ mg }{5.0 \ g} \times 100\%}[/tex]

[tex]\mathbf{ = \dfrac{17.782 \ mg }{5000 \ mg} \times 100\%}[/tex]
