Answer:
A simple answer: Carnivores don't eat plants only flesh. So they would not need soil. But it would be hard for Carnivores to get energy because they get energy indirectly from the animals (herbivores) that they eat. How do they get the energy from a herbivore you might ask. Herbivores eat only plants and that gives the herbivore the plant's energy; but if the herbivore gets eaten, it is indirectly transferred into the Carnivore. Hope this helped!!
Carnivore = only feeds on flesh
Herbivore = eats only plants
Omnivore = eats plants and animals/flesh

sh
Answer: b
Explanation:
I took the test
The correct answer is LiOH and Li2SO4.
A strong acid is neutralized by a strong base to yield a normal salt.
A neutralization reaction is a reaction between an acid and a base to yield salt and water only.
An acid can be strong or weak. A base can also be strong or weak. "Strong" or "weak" has to do with the extent of ionization of the acid or base in water. Usually, a strong acid is neutralized by a strong base.
Since H2SO4 is a strong acid, it will require a strong base such as LiOH to neutralize it and the product will be the normal salt Li2SO4.

By referring to the particulate theory of mater, explain the following statement: Oxygen gas is very easy to compress when pressure is applied
By referring to the particulate theory of matter, explain the following statement: A solid lump of iron has a high density .
Answer:
See explanation
Explanation:
According to the particulate theory of matter, gas particles do not interact with each other. A gas is composed of isolated particles moving at high velocities and collide frequently with each other and the walls of the container.
Since the particles of a gas are mostly isolated, it is easy to compress the gas when pressure is applied thereby bringing the gas particles closer together.
On the other hand, in the solid state, the particles that compose matter are close together. These particles only vibrate about their mean positions due to strong intermolecular interaction between particles. The fact that the particles of the solid ion are so close together makes the solid iron lump to possess high density.
what is the difference between the chemical bonds formed in molecules of O2 and the chemical bonds formed in the crystal of NaCi
Explanation:
The bond between two oxygen atoms is covalent (covalent bonding is bonding between Non metals (the electrons are shared)).
The bond between the Na and Cl (NaCl) is ionic (ionic bonding is bonding between a metal (in this case the Na) and a non metal (the Cl). This type of bonds deals with the metal losing electrons and the non metal gaining electrons. The metal therefore become positively charged (so it becomes ionic) and the non metals gain electrons and become negatively charged (also becomes ionic/ forms an ion). The opposite charges attract each other and this is why they bond.
Which statements about a phosphorus atom, P, are correct?
1. The nucleon number is 16.
2. The number of outer electrons is 5.
3. The proton number is 15.
Answer:
3. The proton number is 15.
Explanation:
Phosphorus, P is the element with the atomic number = 15. The atomic number = Number of protons. That means:
3. The proton number is 15.
Now, the number of protons = Number of electrons = 15.
And, nucleon number = Number of protons + number of neutrons. The must abundant phosphorus atom contains 16 neutrons and nucleon number is: 15+16 = 31.
Thus, we can know which statement is true.

El método de cristalización sirve para separar agua salada y obtener ambos componentes por separado
Answer:
Si.
Explicación:
Sí, el método de cristalización se utiliza para separar la sal del agua y obtener los componentes de la sal y del agua por separado. La cristalización es un método o técnica que se utiliza para purificar compuestos sólidos. Este proceso funciona mejor debido a las diferentes solubilidades del compuesto deseado y las impurezas que están presentes en un solvente dado. El proceso de cristalización implica enfriar agua salada para formar cristales de hielo puro. Luego, los cristales de hielo se separan de la salmuera no congelada, se lavan para eliminar la sal residual y luego se derrite la solución para producir agua dulce.

According to the kinetic-molecular theory, the average kinetic energy of gas particles depends on which factor?
Answer:
Temperature.
Explanation:
Kinetic molecular theory of gases states that gas particles exhibit a perfectly elastic collision and are constantly in motion.
According to the kinetic-molecular theory, the average kinetic energy of gas particles depends on temperature.
This ultimately implies that, the average kinetic energy of gas particles is directly proportional to the absolute temperature of an ideal gas. Thus, an increase in the average kinetic energy of gas particles would cause an increase in the absolute temperature of an ideal gas.
Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).
Please select the word from the list that best fits the definition

The second reaction in the formation of sulfuric acid occurs slowly.
2 upper S upper O subscript 2 (g) plus upper O subscript 2 (g) right arrow 2 upper S upper O subscript 3 (g).
NO2 is added to the reaction to speed it up. In which form would this substance be a homogeneous catalyst for this reaction?
NO2(g)
NO2(l)
NO2(s)
NO2(aq)
Answer: The correct option is [tex]NO_2(g)[/tex]
Explanation:
A catalyst is defined as the chemical species that increases the reaction rate but does not participate in it and is left behind after the completion.
A homogeneous catalyst is one that is present in the same phase as the reactants and products.
A heterogeneous catalyst is one that is present in different phase as that of reactants and products.
For the given chemical reaction:
[tex]2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)[/tex]
As all the reactants and products are in gaseous state so, the homogeneous catalyst must also be in the gaseous state only.
Hence, the correct option is [tex]NO_2(g)[/tex]

Often, several different labs need to share a very small amount of evidence. It is important that the chain of custody be maintained. If the chain of custody is broken, then the evidence may not be allowed in a court proceeding. Identify the error in the following case. After obtaining the evidence, the first lab technician removed the tape that contained the signatures of the crime scene evidence collector. On completion of her examination of the evidence, the lab technician put the evidence into a paper bindle, and inserted thee bindle into an evidence bag. The technician sealed the bag in the same place as the original crime-scene investigator. After carefully sealing the bag, the lab technician signed her name across the tape. She completed the chain-of-custody form on the outside of the evidence bag and brought the evidence to the next lab technician at the crime lab.
Answer:
The errors in the case are;
1. Error; Removing the tape containing the signatures of the crime scene evidence collector, which removes the record/signature of the crime scene evidence collector in chain of custody
Correct; The original signature of the crime scene evidence collector should left on the package and the package should be opened at another location
2. Error; Placing the reseal back at the same location of the initial seal placed by the evidence collector
Correct; The package should be opened at a different area from the point in which it was sealed when it is received
3. Incorrect; Resealing the bag at the same point it was opened
Correct; On completion, the lab technician should place the evidence with the package, which was opened at a location different from its original opening, in a new package, which is then sealed and she should sign off on the evidence chain-of-custody log before bringing the evidence to the next lab technician at the lab
Explanation:
Evidence collection process requires the documentation of the specific place or spot that the evidence was located, proper evidence packaging, and maintenance of a correct chain of custody
A complete and proper chain of custody
a) Ensure the number of persons who handle the evidence is limited
b) Verify tat the chain of custody documents lists all the names, dates and identification number
c) Ensure to collect signed or secured receipt when the evidence is being transferred
