Use two analogies to describe quantized change.
Answer:
See explanation
Explanation:
1) A flight of stairs because there is a specific number of steps one may take at a particular time. That is, the number of steps that can be taken at a given time is not continuous.
2) The gear system of a car: The gear system of a car can only take whole number integer values. It is not continuous and only one level of gear can be attained at a given time.
The two analogies that I used to describe quantized change are;
- Notes on a Piano
- Digital Clock
Quantized change is simply means that the change is definite under certain restrictions such as the gears in our cars. This means that change comes in discreet amounts.
The 2 analogies that I can use to describe it are as follows;
1) Notes on a Piano; When we are turn on a piano, the notes on the piano are fixed and as such we can only play the notes that the keys can hit.
2) Digital clock; The representation of time in digital clocks is in terms of numbers which can be said to be discrete variables.

Which row in the chart below best
describes asexual reproduction?
3
2
1
4
Answer:
1
Explanation:
Asexual reproduction is the ability of an organism to produce offspring identical to themselves.
In asexual reproduction, the number of parents is one, and the generation of offspring is genetically identical to a single parent. Therefore, row (1) best describes asexual reproduction.
What is asexual reproduction?Asexual reproduction can be described as a mode of reproduction in which a new offspring is generated by a single parent. The new individuals generated are genetically and physically identical to each of their parents. Asexual reproduction can be defined as the mode of reproduction in which the production takes place of offspring by a single parent.
Asexual reproduction can be observed in both multicellular and unicellular organisms. This process does not include gamete fusion and no change in the number of chromosomes either. Asexual reproduction will inherit the same genes as the parent.
Characteristics of Asexual Reproduction are single parent, no fertilization takes place, occurs in a very short time, and grows rapidly. The offspring in asexual reproduction is genetically similar.

Which statement best explains why aluminum is a pure substance? Group of answer choices Aluminum is one type of atom and its composition is always the same. Aluminum has a composition that is evenly mixed. The aluminum atom cannot be seen with a microscope. Aluminum contains substances that are not bonded together.
Answer:
The best explanation for both the first and second claims is that aluminum is a pure substance: Aluminum is one form of atom and its structure is always the same. Aluminum has an evenly blended composition.
Explanation:
Aluminum is one type of atom and its composition is always the same, this statement also gives the property of a pure substance . In fact, pure substances are often homogeneous and contain only one form of atom or molecule.
One of a pure substance's key characteristics is that it has a uniform composition that is homologous in nature, and can be mixed uniformly throughout. ALUMINUM's second statement notes the property of a pure substance. Aluminum is also homologous in terms of occurrence.
The atoms are very small and have a diameter of around 1 x 10-10 meters. It's difficult to view them using a light microscope due to their limited size. Although it may not be possible to view an atom using a light microscope, a number of techniques have been developed, such as electron microscopy, to observe and research the structure of atoms. Therefore, the statement that the aluminum atom can not be seen through a microscope does not explain the pure content of aluminum.
This argument - 'Aluminum contains substances which are not bound together' does not explain the fact that it is a pure material as it notes that the property of a pure material does not exist in relation to its chemical bonds.
.Therefore, the first and second aluminum statements give the best description of a pure material.

If 6.00 g of carbon is burned completely, what volume of carbon dioxide gas is released at STP? 6.0 L 11.2 L 22.4 L 134.4 L
Answer:
11.2
Explanation:
Find molar mass of carbon 12.01 g/mol then divide by 6.00 g of Carbon, then divide by STP 22.4 L = 11.19 and round to sig fig = 11.2 L
11.2 L volume of carbon dioxide gas is released at STP. Hence, option B is correct.
What is an ideal gas equation?The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).
For this question, use the formula PV=nRT firstly, define your knowns (this requires you to calculate moles of carbon)
Molar mass of carbon = 12.01 g/mol
Moles carbon=[tex]\frac{mass}{molar \;mass}[/tex]
Moles carbon=[tex]\frac{6.00 g}{12.01 g/mol }[/tex]
Moles carbon= 0.4995836803 moles
P=101.3 kPa
V=?
n= 6.0÷12 = 0.5
R= 8.31
T= 273 K
V= (0.5 x 8.31 x 273) ÷101.3
=11.19
Therefore, 11.2 L of carbon dioxide will be produced.

Answer:
Gas, Solid, or liquid
Explanation:
Which of the elements from above (S,Cu, Ar) are considered unreactive? (Explain why using the
concept of valence electrons)
Answer:
Ar
Explanation:
Valence electrons in an atom or element play important role in making an element reactive or unreactive. Valence electrons are the electrons present in the outermost shell of the atom that participates in a chemical reaction and forms a chemical bond with other atoms. Elements having no valence electrons are stable and acts unreactive.
Argon or Ar is the unreactive element from the given elements because there are no valence in argon and all the three electrons shells are full. Electronic configuration of Ar is [Ne]3s23p6 which shows the stability of argon.
Hence, the correct answer is "Ar".

Answer:
C
Explanation:
Have anice day
This electron cloud model of aluminum has 3 energy levels with 3 electrons on its outer energy level. Thus option C is correct.
What is electron cloud?Electron cloud model is a type of model of an atom in which the atom consist of nucleus surrounded by a group of electrons. According to this model, the position of the electron at any given time is not known.
This model explains the zone of probability which describe the location of electron due to uncertainty principle. This model is described by Albert Einstein, Max Planck and Niels Bohr that electrons transmit energy and its properties that linked to light and energy.
The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. The total electrical charge of the nucleus is +Ze, where e is the elementary charge equals to 1,602 x 10-19coulombs.
Every electron is influenced by the electric fields produced by the positive nuclear charge and have (Z – 1) negative electrons in the atom.
Thus option C is correct.

Animals and Animal-like Protists share some characteristics. Tell how the organisms in these groups are the same? Why do you think scientists have placed them in different groups
Answer/Explanation:
Animals are multicellular heterotrophic organisms, meaning they cannot generate their own food, they rely on external sources of nutrition.
Protists are any eukaryotic organism that cannot be classified as an animal, plant, or fungus. The grouping is more used for convenience than anything else.
Like animals, animal-like protists can move freely and are heterotrophic. However, unlike animals, they are usually unicellular, and much simpler than animals
By mistake, a quart of oil was dumped into a swimming pool that measures 25.0 m by 30.0 m. The density of the oil was 0.750 g/cm3. Assuming the oil spread into a uniform, thin layer over the water, how thick was the oil slick?
The oil slick thick = 1.257 x 10⁻⁶ m
Further explanationVolume is a derivative quantity derived from the length of the principal
The unit of volume can be expressed in liters or milliliters or cubic meters
The volume of the aquarium is almost the same as the beam namely:
V = length x width x height
1.06 quart = 1 L
1 quart = 0.943 L=0.943 x 10⁺³ m³
volume of oil = volume of swimming pool
0.943 x 10⁺³ m³ = 25 x 30 x h
