What is the difference between an orbit in the Bohr model of the hydrogen atom and an orbital in the quantum mechanical model
Answer:
See explanation
Explanation:
In Bohr's theory, electrons are found in specific regions in space called orbits. These orbits are also called energy levels. An electron may move from one energy level to another by absorbing or emitting energy.
In the wave mechanical model, electrons are not found in a particular region in space according to Heisenberg's uncertainty principle.
We rather define a certain region in space where there is a high probability of locating the electron. This region in space where there is a high probability of locating the electron is called an orbital.
Hence, in the Bohr's model of the atom,electrons can surely be found in orbits while in the wave mechanical model, the orbital is a probability function that describes a region in space where an electron may be found.
If charge on only one object is tripled, determine the new force between them:
Answer:
+3·F
Explanation:
The number of objects in the given system = 2 objects
The charge on each object are; q₁ = -Q, q₂ = -Q
The force acting between the objects = +F
The distance between the objects = 2·d
The formula for the force acting between two charged particles is given as follows;
[tex]F=K \times \dfrac{q_{1} \times q_{2}}{r^{2}}[/tex]
Therefore, we get;
[tex]F=K \times \dfrac{-Q \times -Q}{(2\cdot d)^{2}} = K \times \dfrac{Q^2}{4 \cdot d^2}[/tex]
By tripling the charge, q₁, on the first object, we get;
q₂ = 3 × (-Q)
[tex]F_2=K \times \dfrac{-3 \cdot Q \times -Q}{(2\cdot d)^{2}} = K \times \dfrac{3 \cdot Q^2}{4 \cdot d^2} = 3 \times +F = +3\cdot F[/tex]
Therefore, the new force between them, F₂ = +3·F
An ice cube melting is a physical change b. An ice cube melting is a chemical change c. Paper burning is a physical change d. Paper burning is a chemical change e. Bubbles forming when soda pop is poured into a glass is a physical change f. Bubbles forming when soda pop is poured into a glass is a chemical change g. Hard-boiling an egg is a physical change h. Hard-boiling an egg is a chemical change
Answer:
An ice cube melting is a physical change because melting doesn't change the composition of the element. Paper burning is a chemical change because combustion occurs. Bubbles forming in a soda does involve chemical changes. Hard-boiling an egg is a chemical change because the egg's composition changed.

What is the equilibrium constant of pure water at 25°C
Please help me with this activity!! I have to submit it ASAP. It's attached as a pdf. Not too long and for an Honors Electrons lesson.
(1) Seven electrons
1s² 2s²2p³
There are two electrons in the 2s subshell and three in the 2p subshell. The remaining two electrons are in the inner 1s subshell.
(2) 22 electrons
1s² 2s²2p⁶ 3s²3p⁶ 4s²3d²
There are two electrons in the 4s subshell and two in the 2p subshell. The remaining 18 electrons are in the inner subshells.
(3) 17 electrons
1s² 2s²2p⁶ 3s²3p⁵
There are two electrons in the 3s subshell and five in the 2p subshell. The remaining 10 electrons are in the inner subshells.
(4) n = 4, l = 2
(5) N=2 I=0 MI=0
(6) There can be two electrons in one orbital maximum. The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max.
(7) n = 4 can hold up to 16 electrons
There are 4 sublevels; 42, 4p, 4d and 4f
4s (1 orbital), 4p (3 orbitals)
4d (5 orbitals), 4f (7 orbitals)
Maximum number of electrons in energy level: 16
s = 1 orbital
p = 3 orbitals
d = 5 orbitals
f = 7 orbitals
Add these up;
1 + 3 + 5 + 7 = 16
(8) 14 electrons If l = 3, the electrons are in an f subshell. The number of orbitals with a quantum number l is 2l + 1, so there are 2×3 + 1 = 7 f orbitals. Each orbital can hold two electrons, so the f subshell can hold 14 electrons.
sorry i didn't do the last two.. also sorry if some or none of these are correct, i tried my best
Aluminum hydroxide, with heat, creates__
Which of the following
Combination,decomposition,
Single replacement,
Double replacement,
Combustion
Answer: Decomposition is the answer
Explanation: why because aluminium hydroxide would decomposes in the presence of heat and would form an oxide which is aluminium oxide and would also form water as a product.

How many ATP molucules may by synthesed in the case of full methabolism in MUSCULE of oligosaccharide which molucular weight is 48942?
Answer:
About 96 to 256 ATP molecules are produced.
Explanation:
About 96 to 256 ATP molecules may be synthesized in the full metabolism in oligosaccharide because one oligosaccharide molecule has 3 to 8 glucose atoms. About 30 to 32 ATP are produced from one glucose molecule so from three glucose molecule, 96 ATP produced whereas 256 ATP molecules are produced from 8 glucose molecules so we can say that About 96 to 256 ATP molecules from one oligosaccharide.

if slowing down is the response to seeing a blinking yellow light is it conditioned or unconditioned?
Answer:
Conditioned
Explanation:
Naturally, you do not slow down when you see a yellow light. That response is learned, therefore it is a conditioned response.
