Answer:
The awnser is D
Explanation:
Since the black pieces absorb light better than white pieces, the white pieces will reflect light better. But since color doesn't affect sound, the sound waves are reflected the same.
The compound is used in medicine as a source of magnesium ions, which are essential for many cellular activities. Magnesium chloride has also been used as a cathartic and in alloys. To low
Answer:
Bohr's model
Explanation:
Rutherford's experimental evidence best supports the Bohr's model. Recall that in the Bohr's model, the Rutherford model was regarded as a fundamental stepping stone.
Experimental evidence from the Bohr's model shows that the atom is not a sphere of positive charges in which negative charges were embedded. It would have been impossible for Neils Bohr to build the quantum theory from such a model.
Hence, the nuclear theory of Rutherford provided a fundamental stepping stone and experimental backup for the Bohr's model of the atom.
All other models mentioned in task 1 (Dalton, Thompson and Bohr) all mention the fact that the atom is made of particles. Thompson effectively described the particles as negative and positive in nature. Bohr took the idea further by proposing that the negative particles (electrons) were actually found in energy levels that are quantized.
The correct answer is industrial smog. This type of smog exists in coal power plants which creates smoke and sulfur dioxide which may mix with fog creating a thick blanket of haze. Sulfur dioxide is one primary component of an industrial smog.
Answer:
NaHCO3 sodium bicarbonate is baking soda; added to the acetic acid, it forms sodium acetate (aqueous), CO2 gas & water. Remove the water & solid sodium acetate remains.
