Yes, electron follows the same path when it absorb and loses energy.
Yes, when an electron moves from a higher orbit to a lower orbit it always follow the same path as it moves from a lower orbit to a higher orbit. When electron absorb energy it has the power to move from lower orbit to higher orbit or energy level.
While on the other hand, when an electron loses that energy, it comes back to its original position from which it moves earlier when it absorb energy so we conclude that electron follows the same path when it absorb and loses energy.

List two differences between a map and a giobe
Answer:
1. A map is two dimensional, while a globe is three dimensional
2. A globe is a scaled down representation of the entire Planet Earth. A map can represent an area of any size.
Explanation:
1. A map is usually a sheet of rectangular paper that is a flattened image of an area as seen from the top. A globe on the other hand is a sphere which is a 3D shape.
2. Earth is in the shape of a sphere, so Globes are a smaller representation of the planet. A map can be for a city, state, country, or the world.

Can a stable compound be made from these two atoms? Explain why or why not.
The given oxygen and lithium atoms are unable to form a stable compound.
The given atoms to form a stable compound has been oxygen and lithium.
A stable compound has been formed when the transfer of atom has been resulted in the completion of the valence shell of both the electrons.
The oxygen has 6 valence electrons and require to gain 2 electrons to form the stable compound. The Lithium has 3 electrons and has been able to lose 1 electron to form a stable compound.
Since, the formation of stable compound between oxygen and lithium requires transfer of 2 electrons, and there has been availability of 1 electron from Li. Thus, the atoms are unable to form a stable compound.

Answer:
A
Explanation:
Its a becuse vinegar and baking soda make carbon dioxide
The equation best models the reaction of vinegar (C2H4O2) and baking soda (NaHCO3) -
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2
The overall process can be summarized by the following word equation:
baking soda (sodium bicarbonate) reacts with vinegar (acetic acid) that yields carbon dioxide and water with sodium acetateThe chemical equation for the overall reaction is:NaHCO3 (s) + CH3COOH (l) → CO2(g) + H2O (l) + NaC2H3O2
The chemical reaction actually occurs in two steps. there is a double displacement reaction in which acetic acid in the vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid: NaHCO3 + HC2H3O2 → NaC2H3O2 + H2CO3 Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas:H2CO3 → H2O + CO2
Thus, the equation best models the reaction of vinegar (C2H4O2) and baking soda (NaHCO3) -
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2

Which statement describes a shortcoming of Rutherford’s model of the atom?A.
It incorrectly placed most of the atom’s mass in the nucleus.
B.
It did not explain how electrons behaved and why they don’t collide with the nucleus.
C.
It did not account for the fact that atoms have equal numbers of protons and electrons.
A shortcoming of Rutherford’s model of the atom is it did not account for the fact that atoms have equal numbers of protons and electrons. Therefore, option C is correct.
What is rutherford's model ?Ernest Rutherford, a scientist who was born in New Zealand, developed the Rutherford model to explain an atom. Rutherford oversaw the Geiger-Marsden experiment, which, after Rutherford's analysis in 1911, indicated that J. J. Thomson's plum pudding model of the atom was flawed, in 1909.
The first person to recognize an atom's nucleus was Rutherford. He attacked gold with -particles and discovered that there was positively charged material inside the atom as a result.
It did not explain the distribution of the atom's negatively charged electrons around its positively charged nucleus.
Thus, option C is correct.

The phrase which best describes nuclear fusion is: A. the process by which small nuclei combine into a larger nucleus.
A nuclear reaction can be defined as a type of chemical reaction in which the nucleus of an atom of a radioactive chemical element is transformed by either being joined (fusion) or split (fission) with the nucleus of another atom of a radioactive chemical element and accompanied by a release of energy.
Generally, there are two (2) main types of nuclear reaction and these include:
Nuclear fission: it involves the collision of a heavy atomic nucleus with a neutron, thereby causing a split and release of energy.Nuclear fusion: it involves the joining of two smaller nuclei of atoms to form a single massive or heavier (larger) nucleus with the release of energy.In conclusion, nuclear fusion is best described as the process by which small nuclei combine into a larger nucleus, accompanied by a release of energy.
