Answer:
the answer is soluble because compounds containing the C2H3O2− ion are soluble in water
The second atom emits light with more energy.
The first and second atoms absorb energy without emitting light.
The first and second atoms emit light with the same amount of energy.
The correct option is this: THE FIRST ATOM EMITS LIGHT WITH MORE ENERGY.
In the question given above, the level 1 mentioned in the question refers to the ground state of the electrons while level 2 and level 3 refer to excited states of hydrogen electrons. When an atom is in an excited state, it possess more energy and it is unstable, thus, it tends to return to the ground state after sometime to attain stability. As the atom return to the ground state, it loses its energy by emitting light. The higher the level of excitation, the more the light that will be emitted when the atom is returning to the ground state. Thus, an atom returning to the ground state from level 3 has more energy and will emit more light when returning to the ground state than an electron in level 2.
Silicon generally forms at least polar covalent bonds, like carbon, as befits its status as a Gropu 4A nonmetal. The only obvious exception I can think of is SiC, which despite the similarity you might expect to graphite or diamond does, I think, have significant ionic or metallic character to its bonding in the solid state.
A. the cumulative nature of science
B. the quantitative nature of science
C.the importance of thorough review of scientific papers
D. the importance of not publishing science until it is final
collect more data to support their hypothesis
Answer: Based on experimental data
Explanation: The hypothesis is not the ultimate proven theory, the more a preliminary assumption on the basis of which further research is carried out with the help of experiments in order to prove the hypothesis as accurate. If the experiments carried out showed that the hypothesis is wrong, it is necessary to revise the hypothesis and set up a new experiment.
