1. A principle under which all persons, institutions, and entities are accountable to laws that are: Publicly promulgated. Equally enforced. Independently adjudicated. And consistent with international human rights principles.
2. The laws are clear, publicized, and stable; are applied evenly; and protect fundamental rights, including the security of persons and contract, property, and human rights. The processes by which the laws are enacted, administered, and enforced are accessible, fair, and efficient.
3. It codifies the core values of the people. Courts have the responsibility to interpret the Constitution's meaning, as well as the meaning of any laws passed by Congress. Everything they do must be based on the law, and they are accountable for their decisions. That means officials are held responsible for the choices they make.
Questions and Problems 22 When water is heated, the temperature eventually reaches a constant value and forms a plateau on the graph. What does the plateau indicate?
Answer:
It indicates phase changes: melting then later boiling.
Explanation:
On the heating curve of water, the plateau marks phase change transitions.The temperature remains constant during this period.The first phase change is melting of water.The second phase change is boiling of water to gas.
What causes hurricanes in the northern hemisphere to roster counterclockwise ?
-ocean temperatures
-the saffir-Simpson scale
-the strength of the eyewall
-the coriolis effect
Answer: The answer is D.
Explanation:
As the air rushes toward the center, it winds up moving in a curved path thanks to the Coriolis effect. This creates a circular spinning pattern as air travels from areas of high pressure to low pressure. That's why hurricanes originating in the northern hemisphere rotate counterclockwise.

is an organism that breaks down waste and dead organisms.
Answer:
A consumer is an organism that eats other organisms to gain energy; it is also called a heterotroph.
A producer is an organism that makes its own food; it is also called an autotroph.
A decomposer is an organism that breaks down waste and dead organisms.
Explanation:
Green plants are examples of autotrophs that make their own food by photosynthesis - they don't rely on other organisms to provide them with energy.
In contrast, many organisms rely on other organisms as an energy source. These organisms are called consumers or heterotrophs. They consume producers and other consumers.
Decomposers such as some fungi, bacteria, and certain insects break down dead or decaying biological material and recycle the nutrients back into the soil.

Why do we assume that the color of the flame is due to the positive ion ?
Answer:
Any element placed in a flame will change its color. Atoms are made of positively charged nuclei, about which negatively charged electrons move according to the laws of quantum mechanics. Quantum mechanics constrains them to appear in various distinct patterns, called orbitals. (Orbitals are a lot like planetary orbits, but blurrier, so that you're never quite sure just where the electrons are.)
Left on their own, the electrons of an atom tend to relax into orbitals that leave the atom with the lowest possible energy--its ground state. Putting atoms into a flame, though, adds energy to the looser electrons farthest from the nucleus and pushes them into other orbitals. Eventually, these excited electrons drop back to where they ought to be, and in so doing, they release the energy they stored up as particles of light, called photons.

Calculate the number of grams of CuSO4 found in 3.29 mL of a 4.00 M CuSO4 solution. ______ grams CuSO4
Answer:
2.08g
Explanation:
Given parameters:
Volume of CuSO₄ = 3.29mL
Molarity = 4M
Unknown:
Mass of CuSO₄ = ?
Solution:
Let us find the number of moles from the given parameters first;
Number of moles = molarity x volume
1000mL = 1L
Express the volume of the given CuSO₄ in L = 3.29 x 10⁻³L
Number of moles = 4 x 3.29 x 10⁻³ = 0.013mol
So;
Mass of CuSO₄ = number of moles x molar mass
Molar mass of CuSO₄ = 63.6 + 32 + 4(16) = 159.6g/mol
Mass of CuSO₄ = 0.013mol x 159.6g/mol
Mass of CuSO₄ = 2.08g

What is the Enthalpy of reaction?
What is the total Enthalpy of Reactants and Products? (Kj/Mol)
Is this a endothermic or exothermic reaction?
Answer: hope this helps!
Explanation:
Specific heat capacity of a substance is the amount of heat required to raise the temperature by one degree Celsius of one gram of a substance. Therefore, the enthalpy of reaction is -2219.9KJ/mol and the reaction is exothermic reaction.
What is Enthalpy?Enthalpy term is basically used in thermodynamics to show the overall energy that a matter have. Mathematically, Enthalpy is directly proportional to specific heat capacity of a substances.
Mathematically,
C[tex]_3[/tex]H[tex]_8[/tex](g) + 5O[tex]_2[/tex](g) [tex]\rightarrow[/tex]3CO[tex]_2[/tex](g) + 4H[tex]_2[/tex]O(g)
Mathematically, the formula for enthalpy of a reaction can be given as
ΔH for reaction= 3 ×ΔH of CO[tex]_2[/tex] + 4 ×ΔH of H[tex]_2[/tex]O- ΔH of C[tex]_3[/tex]H[tex]_8[/tex]+ 5 ×ΔH of O[tex]_2[/tex]
= 3 ×393.5KJ/mol+ 4 ×285.8- 103.8+ 5 ×0
=-2219.9KJ/mol
The enthalpy of reaction is -2219.9KJ/mol. since the value of enthalpy has negative sign, the reaction is exothermic reaction.
Therefore, the enthalpy of reaction is -2219.9KJ/mol and the reaction is exothermic reaction.

What is the maximum kinetic energy of an ejected electron if silver metal is irradiated with 224 nm light? The
threshold wavelength for a silver metal surface is 267 nm.
Give your answer accurate to three significant figures. Use exponential notation (e.g. 1.23e-19).
Answer:The maximum kinetic energy KEe of ejected electrons (photoelectrons) is given by KEe=hf−BE KE e = h f − BE , where hf is the photon energy and BE is the binding energy (or work function) of the electron to the particular material.
Explanation:
The maximum kinetic energy of an ejected electron if silver metal is irradiated with 224 nm light is 4.66eV.
What is kinetic energy?Kinetic energy is defined as is a form of energy that an object and particle has by the reason of its movement.
It is also defined as the measure of the work that an object does by the virtue of its motion.
Kinetic energy can be expressed as
KE = 1/2 mv²
KE = hc / ∧
KE = 6.63 x 10⁻³⁴ x 3 x 10⁸ / 267
KE = 7.45 x 10⁻¹⁹ J
The charge on electrons 1.6 x 10⁻¹⁹ C
So, Maximum kinetic energy = 7.45 x 10⁻¹⁹ / 1.6 x 10⁻¹⁹
= 4.66 eV
Thus, the maximum kinetic energy of an ejected electron if silver metal is irradiated with 224 nm light is 4.66eV.

Is this a scientific model? Use complete sentences to explain why or why not.
Answer:
its a scientific model
Explanation:
It is a scientific model because it is showing the water cycle. In the water cycle it is scientifically showing how water circulates through the Earth. For example, the water in the ocean evaporates which is evaporation, then it condensates into a cloud that then becomes condensation and the condensation makes precipitation when it rains. When it falls to the ground, it then becomes a runoff down a hill.
