Elements are represented by their symbols with the first letter capitalized and the rest in lowercase. Copper is represented by Cu and Bromine is represented by Br. When combined to for a compound, the format of the symbols remain. Hence, the correct format would be CuBr.
Thus, the answer is C: CuBr<span>.</span><span />
The quantum model is regarded as the most current model to explain the composition of an atom. The Bohr model and the quantum model are fundamentally different in that the former explains the particle behavior of an electron while the latter explains its dual nature as a wave and a particle.
<h3>
What is the Bohr Model?</h3>
The Bohr model of the atom was put forth by Neil Bohr in 1915. It was developed by altering Rutherford's atomic model. Rutherford demonstrated how a positively charged nucleus is surrounded by negatively charged electrons in his nuclear model of an atom.
The Bohr hypothesis modified the atomic structure model by explaining that electrons move in fixed orbitals (shells) and not anywhere in between. He also demonstrated the fixed energy of each orbit (shell). Bohr added electrons and their many energy levels to Rutherford's revised concept of the atom's nucleus.
In Bohr's theory, there is a tiny, positively charged nucleus that is surrounded by negatively charged electrons that orbit the nucleus. According to Bohr, an electron that is farther from the nucleus has more energy than an electron that is closer to the nucleus.

Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,
Less than 0.4 then it is Non Polar Covalent
Between 0.4 and 1.7 then it is Polar Covalent
Greater than 1.7 then it is Ionic
For Li and O,
E.N of Oxygen = 3.44
E.N of Lithium = 0.98
________
E.N Difference 2.46 (Ionic Bond)
For Cl and F,
E.N of Fluorine = 3.98
E.N of Chlorine = 3.16
________
E.N Difference 0.82 (Mildly Polar Covalent Bond)
For Ca and S,
E.N of Sulfur = 2.58
E.N of Calcium = 1.00
________
E.N Difference 1.58 (Polar Covalent Bond)
Based on the question, it is evident that the question is based on Boyle's Law which we will use to find the answer necessary.
Now, Boyle's Equation: P₁V₁ = P₂V₂
V₂ = P₁V₁ ÷ P₂
∴ V₂ = (12.5L × 42.0 cm · Hg) ÷ 75 cm · Hg
⇒ V₂ = 7 L
Thus, the <span>volume when the pressure has increased to 75.0 cm Hg is 7 Litres.</span>
Answer:
1- Environmental Value System or EVS is a worldview that molds the way both individuals and the societies they form perceive and therefore evaluate environmental concerns.
2-Entropy/ the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work.
3-Equilibrium/a state of balance between opposing forces or actions that is either static
4-Feedback/a return of information about a result or the returned portion of a process.
5-Feedback,negative/ is a self-regulatory system in which it feeds back to the input a part of a system's output so as to reverse the direction of change of the output.
6-Feedback,positive/ is the amplification of a body's response to a stimulus.
7-Gaia/ all organisms and their inorganic surroundings on Earth are closely integrated to form a single and self-regulating complex system
8-Model/a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes.
