Which statement correctly describes why a compound is a pure substance?
A compound is not a pure substance because each of its molecules is made up of the atoms of two or more different elements.
A compound is a pure substance because its molecule cannot be broken down into simpler particles by physical means.
A compound is not a pure substance because it is not an element, and only elements are pure substances.
A compound is a pure substance because it consists of two different elements, which are pure substances.
Answer:
The second statement
Explanation:
Because it can't be broken by physical means
A compound is a pure substance because its molecule cannot be broken down into simpler particles by physical means. Therefore, option B is correct.
What is pure substance ?A kind of matter with a predictable chemical composition and physical properties is referred to as a chemical substance. According to certain references, chemical substances cannot be physically divided into their component parts.
A pure material has a predictable chemical make-up. A material is the same everywhere it is sampled. The safest pure examples for chemistry homework are elements and compounds. Gold, silver, helium, sodium chloride, and pure water are a few examples.
Water only includes one kind of molecule, making it a pure substance. Only molecules made up of one oxygen atom joined covalently to two hydrogen atoms can be found in pure water.
Thus, option B is correct.

Explain any periodic trends you discovered in the 6 physical properties you investigated.
pls help.
Answer:
Periodic trends are specific patterns that are present in the periodic table that illustrate different aspects of a certain element, including its size and its electronic properties. Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or periods, and because of the periodic nature of the elements.
Explanation:
Electron Affinity:
electron affinity is the ability of an atom to accept an electron. Unlike electronegativity, electron affinity is a quantitative measurement of the energy change that occurs when an electron is added to a neutral gas atom. The more negative the electron affinity value, the higher an atom's affinity for electrons.
Electron affinity generally decreases down a group of elements because each atom is larger than the atom above it (this is the atomic radius trend, discussed below). This means that an added electron is further away from the atom's nucleus compared with its position in the smaller atom. With a larger distance between the negatively-charged electron and the positively-charged nucleus, the force of attraction is relatively weaker. Therefore, electron affinity decreases. Moving from left to right across a period, atoms become smaller as the forces of attraction become stronger. This causes the electron to move closer to the nucleus, thus increasing the electron affinity from left to right across a period.
Electron affinity increases from left to right within a period. This is caused by the decrease in atomic radius.
Electron affinity decreases from top to bottom within a group. This is caused by the increase in atomic radius.

One of the following processes does not involve a chemical reaction, that is:
(a) Melting of candle wax when heated
(b) Burning of candle wax when heated
(c) Digestion of food in your stomach
(d) Ripening of banana
Answer:
A.
Explanation:
The melting of wax is just a physical change, not a chemical one, since melted wax can still reharden and go back to its original state. All the other choices are non-reversible, chemical changes.
Hopefully this helps- let me know if you have any questions!
Answer:
Melting of candle wax when heated

If a car can go from 0 to 60 mi/hr in 8.0 seconds, what would be its final speed after 5.0 seconds if its starting speed were 50 mi/hr?
a=
vf=
vi=
t=
Answer:
87.5 mi/hr
Explanation:
Because a = Δv / Δt (a = vf - vi/ Δt), we need to find the acceleration first to know the change in velocity so we can determine the final velocity.
vf = 60 mi/hr
vi = 0 mi/hr
Δt = 8 secs
a = vf - vi/ Δt
= 60 mi/hr - 0 mi/hr/ 8 secs
= 60 mi/hr / 8 secs
= 7.5 mi/hr^2
Now that we know the acceleration of the car is 7. 5 mi/hr^2, we can substitute it in the acceleration formula to find the final velocity when the initial velocity is 50 mi/hr after 5 secs.
vi = 50 mi/ hr
Δt = 5 secs
a = 7.5 mi/ hr^2
a = vf - vi/ Δt
7.5 = vf - 50 mi/hr / 5 secs
37.5 = vf - 50
87.5 mi/ hr = vf

Explanation:
True or false: every time energy is transferred into a substance it is going to change phases or state
Answer: True
Explanation: Transferring energy to or from a substance can change its state. Heating a substance in the solid state will cause it to melt, which changes it to the liquid state. Continued heating will cause the substance to evaporate or boil, which changes it to the gas state.
Some substances in the solid state can change straight to the gas state. This process is called sublimation.
A substance in the gas state condenses when it is cooled, which changes it to the liquid state. Continued cooling causes it to freeze, which changes it to the solid state.

If a mineral with a density of 6 g/cm3 is broken into 3, what is the density of each new piece?
A. 2 g/cm^3
B. 6g/cm^3
C. 18 g/cm^3
D. 12 g/cm^3
Answer:
If a mineral with a density of 6 g/cm3 is broken into 3, the density of each new piece is 6 [tex]\frac{g}{cm^{3} }[/tex]
Explanation:
Density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. In other words, density is the property that matter, whether solid, liquid or gas, has to compress into a given space, the amount of mass per unit volume.
As density is a physical property of matter that is defined as the ratio of an object's mass to its volume, each material or substance has its own density regardless of its size because the ratio between mass and volume is the same.
If a mineral with a density of 6 g/cm3 is broken into 3, the density of each new piece is 6 [tex]\frac{g}{cm^{3} }[/tex]
