What mass of potassium chlorate is needed to generate 114.0 L of O2 at 0.720 atm and 291 K?
Answer:
281 g KClO₃
Explanation:
To find the mass of potassium chlorate (KClO₃), you need to
(1) calculate the number of moles O₂ (using the Ideal Gas Law)
(2) create a balanced equation involving KClO₃ and O₂
(3) convert moles O₂ to moles KClO₃ (using mole-to-mole ratio from balanced equation)
(4) convert moles KClO₃ to grams (using the molar mass of KClO₃)
It is important to arrange the ratios/conversions in a way that allows for the cancellation of units. The final answer should have 3 sig figs like the given values.
(Step 1)
To find the amount of moles O₂, you need to use the Ideal Gas Law equation:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = number of moles
-----> R = Ideal Gas Constant (0.08206 atm*L/mol*K)
-----> T = temperature (K)
You can plug the given values into the equation and simplify to solve for "n".
P = 0.720 atm R = 0.08206 atm*L/mol*K
V = 114.0 L T = 291 K
n = ? moles
PV = nRT <----- Ideal Gas Law Equation
(0.720 atm)(114.0 L) = n(0.08206 atm*L/mol*K)(291 K) <----- Insert values
82.08 atm*L = n(23.879 atm*L/mol) <----- Simplify both sides (multiply)
3.44 moles = n <----- Divide both sides by 23.879
(Step 2)
Unbalanced Equation: KClO₃ (s) -----> KCl (s) + O₂ (g)
Reactants: 1 potassium, 1 chlorine, 3 oxygen
Products: 1 potassium, 1 chlorine, 2 oxygen
As you can see, the amount of each type of atom is not identical on both sides of the reaction. To balance the equation, you can add coefficients in front of particular molecules/elements to alter the amount of each atom type.
Balanced Equation: 2 KClO₃ (s) -----> 2 KCl (s) + 3 O₂ (g)
Reactants: 2 potassium, 2 chlorine, 6 oxygen
Products: 2 potassium, 2 chlorine, 6 oxygen
(Step 3 + 4)
Atomic Mass (K): 39.098 g/mol
Atomic Mass (Cl): 35.453 g/mol
Atomic Mass (O): 15.999 g/mol
Molar Mass (KClO₃): 39.098 g/mol + 35.453 g/mol + 3(15.999 g/mol) = 122.548 g/mol
3.44 moles O₂ 2 moles KClO₃ 122.548 g
------------------------ x ------------------------- x ----------------------- = 281 g KClO₃
3 moles O₂ 1 mole KClO₃

Electrons added to atomic orbitals of the same energy will remain unpaired with parallel spins until the subshell is more than half-filled" is a statement of Select one: O a. Conservation of Energy O b. The Aufbau Principle O c. Hund's Rule O d. The Periodic Law
The correct option is (c) Hund's Rule.
Hund's rule: every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.When assigning electrons to orbitals, an electron first seeks to fill all the orbitals with similar energy before pairing with another electron in a half-filled orbital. Atoms at ground states tend to have as many unpaired electrons as possible. In visualizing this process, consider how electrons exhibit the same behavior as the same poles on a magnet would if they came into contact; as the negatively charged electrons fill orbitals, they first try to get as far as possible from each other before having to pair up.Electrons are negatively charged and, as a result, they repel each other. Electrons tend to minimize repulsion by occupying their own orbitals, rather than sharing an orbital with another electron. Furthermore, quantum-mechanical calculations have shown that the electrons in singly occupied orbitals are less effectively screened or shielded from the nucleus.

What is the mechanical properties of polymers?
The moduli of elasticity and other classes of strength measures, such as the yield and tensile strengths, can be used to characterize the mechanical properties of polymers in a manner that is quite similar to that of metals or other common crystalline materials. The most significant mechanical and elastic characteristics of polymeric materials are summarized generally below:
Strength: Whenever the applied force is greater than a straightforward linear elastic deformation, represents the stress force required to fracture the material sample under investigation. Tensile strength (stretching of the polymer), compressional strength (compressing the polymer), flexural strength (bending of the polymer), torsional strength (twisting of the polymer), and impact strength are some of the most important types of strength quantities used in typical materials characterization measurements (e.g. under the effects of direct hammering).Percent Elongation to Break (Ultimate Elongation): This statistic, expressed as a percentage change in the material's length, describes the maximum strain that the polymer sample can experience before it ultimately breaks (at the aforementioned strength point).Young's Modulus: A measure of a material's total stiffness, it is the ratio of stress to strain in the region of its linearly elastic response.To know more about Mechanical properties of polymers, visit:

Naturally, occurring methane can be found both below ground and under the seafloor and is produced by both geological and biological processes. The largest reservoir of methane gas is found under the seafloor in the form of methane clathrates.
The methane concentration in Earth's atmosphere has increased by about 150% and it accounts for 20% of the total radiative emission from all of the long-lived and mixed greenhouse gases.

What is true about metallic bonds?; Is a metallic bond a true bond?; What do metallic bonds hold together?; Which describes a metallic bond bond of?
A Metallic bond is the type of bond that is formed between two metals by sharing of their free electrons. They are non-polar and non-directional in nature.
In metallic bonds, there is an electrostatic force of attraction which holds together atoms in a metallic substance. Unlike in covalently bonded substances, the valence electrons in a metals are not localized and they can move about freely in a crystal lattice.
As such, due to this random movement, the valence electrons interact with the positive ions present in the crystal and this gives rise to a binding force which hold the metallic bond together.

rank the speed of sound through the following from greatest to least: a. helium b. benzene c. mercury
The the density of the substance that sound travels through directly affects its speed. Helium and benzene are the two liquids of a three media mentioned. Mercury is a metal, but it is also liquid.
What is density, for instance?How much "stuff" is contained in a specific quantity of space is determined by its density. For instance, a block of the harder, lighter element gold (Au) will be denser than a block of heavier element lead (Pb) (Au). Styrofoam blocks are less dense than bricks. Mass per cent volume serves as its definition.
What are density's two characteristics?The two physical characteristics of matter—mass and volume—are necessary for the classification of something as matter. The mass to volume ratio of a substance or item is known as its density. Mass per volume unit or weight divided by volume are two other ways to describe density.
