Scientists group similar organisms together through the process called classification. Each similar groups is classified into different organizations.
What is biological classification?The arrangement of species into groups according to significant similarities is known as biological classification. Then, these groups are broken down into more focused, smaller subgroups. Additional details on the species that make up each subgroup are provided.
Organisms are categorized by scientists to make them simpler to research and to facilitate information sharing. Before biologists properly comprehended genetics, the study of biological classification was conducted.
At first, scientists simply categorized creatures based on their outward appearance. Later, as genetic research developed, classification of organisms was based on the genetic and evolutionary links between them.
Therefore, scientists classify each organisms to suitable organizations.

Explanation:
The value of Kp for the reaction 2 A(g) + B(g) + 3 C(g) → 2 D(g) + E(g) is 18530 at a particular temperature. What would be the value of Kp for the reaction 2 D(g) + E(g) → 2 A(g) + B(g) + 3 C(g)?
Answer:
[tex]Kp2=5.3967x10^{-5}[/tex]
Explanation:
Hello there!
In this case, since the Kp for the first reaction is given, according to the following equilibrium expression:
[tex]Kp=\frac{p_D^2p_E}{p_A^2p_Bp_C^3} =18530[/tex]
However, since the second reaction stands for the reverse of the initial one, the equilibrium expression would be:
[tex]Kp_2=Kp=\frac{p_A^2p_Bp_C^3}{p_D^2p_E}[/tex]
And therefore its Kp the inverse of the aforementioned one:
[tex]Kp2=1/18530\\\\Kp2=5.3967x10^{-5}[/tex]

2. What happens to the temperature of air when it is compressed?
Explanation:
the pressure and temperature of the air increase
reason:
the volume of the space containing air decreases.
Explanation:
Whether you know it or not, compressed air is involved in every aspect of our lives, from the balloons at your birthday party to the air in the tires of our cars and bicycles. It was probably even used when making the phone, tablet or computer you’re viewing this on.
The main ingredient of compressed air is - you guessed it! - air. Air is a gas mixture, which means it consists of many different gases. Primarily these are nitrogen (78%) and oxygen (21%).
The temperature of the air is directly proportional to the mean kinetic energy of these molecules. This means that the air temperature will be high if the mean kinetic energy is large (and the air molecules move faster). The temperature will be low when the kinetic energy is small.
Compressing the air makes the molecules move more rapidly, which increases the temperature. This phenomenon is called “heat of compression”. Compressing air is literally to force it into a smaller space and as a result bringing the molecules closer to each other. The energy that gets released when doing this is equal to the energy required to force the air into the smaller space. In other words, it stores the energy for future use.

What is the correct formula for the missing product from the equation below:
Na2CO3(aq)
+
CaCl2 (aq)
> NaCl +
Answer:
CaCO3 (s)
Explanation:
This equation is a double replacement equation, which means that since Na and Cl and paired, Ca and CO3 will be paired.
Then, you look at the charge of each element and balance
Ca has a 2+ charge
CO3 has a 2- charge
The 2+ charge and the 2- charge will cancel so there is no need for a subscript or to balance the equation
The complete equation will be Na2CO3 (aq) + CaCl2(aq) -> NaCl (aq) + CaCO3 (s)

2KCIO3 -> 2KCI+ 302
How many moles of oxygen are produced by
the decomposition of 6.0 moles of potassium
chlorate, KCIO3?
Answer:
9 moles
Explanation:
The balanced chemical equation for this decomposition reaction is as follows:
2KCIO3 → 2KCI+ 302
Based on this equation, 2 moles of potassium chlorate (KCIO3) decomposes to form 3 moles of oxygen gas (O2).
Hence, 6 moles of pottasium chlorate will decompose to produce;
6 × 3 ÷ 2
= 18 ÷ 2
= 9 moles of O2.

Atomic models are important because, they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter.
Explanation:
We study the various atomic models in our course of study because, it is important for us to know, how did people come to the present concept of an atom. How did physics evolve from classical to quantum physics.
All these are important for us to know and thus, knowledge about various atomic models, their discoveries and drawbacks and finally improvements based on scientific evidence present at that time is important for us to understand the underlying theory very well.

A DAY IN THE LIFE OF METIS JOURNAL. I WROTE IT HOPE U LIKE IT XD
We, who live in the west, were Nomadic. So we always moved from place to place to hunt buffalo and other fur-bearing animals. And now again we have to shift everything we collected , like, all the essential needs we collected. It’s really hard to shift stuff, But when you move to a new place you get to see new beautiful places. They are just so satisfying to see! It’s like all my work(like the shifting work) is paid off. I love it! We always meet the Hudson’s bay company employees, and give them furs which we took from the bissons and other furry animals we hunted. And in exchange they give us their (Hudson’s Bay company) goods. Which is good! Because then we or I won't be able to enjoy that delicious pemmican!
The one reason that makes me proud of my parents is that because of them I am like a translator for both sides in the fur trade! Anyways coming back to the present. As I said before, we were moving today to another place, But on the way some people along with my father will ride the famous York boats carrying supplies to fur posts. I begged my father to take me with him! And as usual he gave me some silly reason for me to stay. And now since I don’t have anything to do I will-..Nevermind, My mom’s calling me. Okay after helping my mom keep the fur posts into the York boats me , my mom, and the others are just relaxing and enjoying nature just to take a break. Since, I am so obsessed with my Journal notebook today I’m just going to sit here and right what comes to my mind. I’m not like the others who always seem to be talking with someone. I like my own space!
I kind of miss my dad already, but he and his fellow members need to travel the waterways from the red river further west and north to hudson bay. These red river carts also travel the trek back and forth over land to St. Paul, Minnesota and to posts in saskatchewan. Speaking about the red river, the only large settlement in the region is the red colony. About 12000 people lived in this colony around Fort Garry. Some were the original Selkirk settlers or their descendents. They had come from Scotland with lord Selkirk when he established the colony in 1811. Many of these original settlers were poor farmers who had been displaced from their lands in scotland. They had endured many hardships in the early years of settlement, including foods, hunger, and sickness. I love studying about other colonies, cultures , history etc.

A mixture of helium, nitrogen and oxygen has a total pressure of 781 mmHg. The partial pressure of helium is 331 mmHg, and the partial pressure of nitrogen is 222 mmHg. What is the partial pressure (in mmHg) of oxygen in the mixture?
Answer:
Partial pressure of O₂ = 228 mmHg
Explanation:
The mixture is made of three gases, He, N₂ and O₂.
Total pressure of it, is 781 mmHg.
There is a law from gases, that indicates the sum of partial pressures of each gas in a mixture will be the total pressure of the system. In conclussion:
Partial pressure of He + Partial pressure of N₂ + Partial pressure of O₂ = Total pressure.
331 mmHg + 222 mmHg + Partial pressure of O₂ = 781 mmHg.
Partial pressure of O₂ = 781 mmHg - 331 mmHg - 222 mmHg
Partial pressure of O₂ = 228 mmHg
What is the molality of a solution containing 18.2 g HCl and 250. g of water?
(EZ Points here)
Answer:
1.99M
Explanation:
Molality can be calculated by dividing the moles of solute by the mass of the solvent i.e.
Molality (M) = n of solute (mol) ÷ mass of solvent (kg)
Based on the information, mass of HCl (solute) = 18.2g, mass of solvent (water) = 250.0g
mole of solute = mass/molar mass
Molar mass of HCl = 1 + 35.5 = 36.5g/lol
mole = 18.2/36.5
mole = 0.499mol
Mass of solvent = 250.0g
In Kg, mass of water = 250/1000
= 0.250Kg
Molality = 0.499/0.250
Molality = 1.996
Molality of the solution = 1.99M

Why would the same amount of gas be produced even if we increase the amount of baking soda?
Answer:
Explanation:
If you are not increasing the amount of vinegar, the adding more baking soda has nothing to react with. The limiting reagent is vinegar (or some other acid).
The usual reaction is
HC2H3O2 + NaHCO3 ===> NaC2H3O2 + HOH + CO2 which is the gas being expelled.
If you increase the NaHCO3 nothing more will happen until you increase the vinegar.
