Why Is It Important To Classify The Millions Of Species On Earth

Answers

Answer:

Why Is It Important To Classify The Millions Of Species On Earth?

The importance mainly is the Taxonomy

Explanation:

The importance mainly is the Taxonomy, which gives an order to living beings, the taxonomy facilitates the study and compression of the species on Earth. Also taxonomy gives the scientific names and classify by their kingdom, family and species, in addition to including their characteristics

One of the important teachings that the different ways of classifying give us have been the great diversity of living beings that inhabit the Earth.

Even the most recent classifications are provisional, because new species are discovered every year. The main value of all classifications is that they have allowed us to know the different organisms that exist much better.

Because without classification there wouldn't be a way to decide what is what and which is which. Classification allows the justification of someone or something to have it's own. For ex : This monkey is red, and this monkey is blue. They have something different between them, they aren't just a "monkey" they are specified under what you can specify about them or what others specify about them. That is a Red Monkey, that is a Blue Monkey. And so forth.

Please help!!!The reaction of sulfuric acid (H2SO4) with potassium hydroxide (KOH) is described by the equation below. Suppose
0.06 L of KOH with unknown concentration is placed in a flask with bromthymol blue indicator. A solution of 0.20 M
H2504 is dripped into the KOH solution. After exactly 0.017 L of H2SO4 is added, the Indicator changes from blue to
yellow. What is the concentration of the KOH? You must show all of your work to earn credit. (4 points)
H2SO4 + 2KOH → K2SO4 + 2H20

Answers

Answer:

$\large\boxed{\large\boxed{1M}}$

Explanation:

1. Reaction

$H_2SO_4+2KOH\rightarrow K_2SO_4+2H_2O$

2. Mole ratio

$(2molKOH)/(1molH_2SO_4)$

3. Sulfuric acid

$Molarity=(moles)/(volume(liters))$

$Moles=Molarity* Volume(liters)$

$Moles=0.20M* 0.017liter=0.034molH_2SO_4$

4. Potassium hydroxide

$(2molKOH)/(1molH_2SO_4)* 0.034molH_2SO_4=0.068molKOH$

$Molarity=(0.068mol)/(0.06liter)=1.13M\approx 1M$
