Answer:
The number of energy levels filled in an atom is determined by the number of orbitals.
Explanation:
The highest numbers of the electrons in a given energy level relies on the presence of number of orbitals. In one orbital it contains two electrons. Electron that are present in the outer energy level of atom are known as the valence electrons. Which remains as the determining factor of the reactivity of the element. Lights are being emitted when an electron comes from higher state to the lower state.
Answer:
398.3 m, 334.2 m
Explanation:
The magnitude of the displacement vector is
v = 520 m
And its direction is
measured as north of east.
The x-component of this vector is given by:
While the y-component is given by
The x-component of the displacement vector (east-west direction) is approximately 398 m and the y-component (north-south direction) is approximately 334 m.
Displacement vectors contain both magnitude and direction information. In the case of a displacement vector 520 m long, pointing 40 degrees North of East, we can break it down into x and y components using trigonometric functions, specifically cosine and sine.
For the x-component (east-west direction), we can use the cosine function because it gives us the adjacent side in a right triangle, which is the east-west direction in our case. Therefore, the x-component will be:
520 m * cos(40) = 398m (rounded to nearest unit).
For the y-component (north-south direction), we can use the sine function because it gives us the opposite side in a right triangle, which is the north-south direction in our case. Hence the y-component will be:
520 m * sin(40) = 334 m (rounded to nearest unit).

Formula: °F = (9/5) (°C) + 32 °C is given so I am solving for °F.
°F = (9/5) (25) + 32
=(1.8*25)+ 32
=45+32
=77
Answer= 77°F is equal to 25°C
A. Convert 35°C to °F
B. Convert 80°F to °C
C. Convert 15°C to °F
D. Convert 25°F to °C
B). Does not dissolve in water
C). Forms crystal structures
D). Does not conduct electricity
Answer:
The answer is D
Explanation:
Ionic compounds have high melting and boiling points.They can dissolve in water.And they donot form crystal structurs by dissolving.And they donot conduct electricity.
Table salt (an ionic compound) forms crystal structures, similar to other ionic compounds, due to the strong electrostatic forces holding its ions in a well-organized lattice. So the correct option is C.
The property of table salt, which is also a property of other ionic compounds, is that it forms crystal structures. Table salt, like all ionic solids, exhibits a crystalline structure because its ions are held together by strong electrostatic forces of attraction in a rigid and well-organized lattice. In contrast, ionic compounds typically have high melting points, dissolve in water, and can conduct electricity when dissolved or molten because ions are free to move, allowing for the flow of electric charge.
