Explanation:
i cant under stand your wuestion
Answer:
1) FALSE
2) TRUE
3) FALSE
4) FALSE
5) TRUE
Explanation:
<em>1)</em> The first excited state corresponds to n=3. <em>FALSE. </em>The ground state corresponds to n=1 and first excited state corresponds to n=2.
<em>2)</em> The wavelength of light emitted when the electron drops from n=3 to n=2 is shorter than the wavelength of light emitted if the electron falls from n=3 to n=1. <em>TRUE. </em>As the n=2 state is in a higher energy than n=1, the energy difference between n=2 and n=3 are shorter than differences between n=1 and n=3 states.
<em>3)</em> It takes more energy to ionize the electron from n=3 than it does from the ground state. <em>FALSE. </em>An electron with a high energy will be less-atracted by the nucleus than a electron with a low energy because is farther of it.
<em>4)</em> The wavelength of the light emitted when the electron returns to the ground state from n=3 is larger than the wavelength of light absorbed to go from n=1 to n=3. <em>FALSE. </em>The energy differences in light emitted and light absorbed is the same.
<em>5)</em> The electron is farther from the nucleus on average in the n=3 state than in the ground state. <em>TRUE. </em>According Bohr's model, the greater energy level, the farther from the nucleus it is.
I hope it helps!
Sulfuric acid or H2SO4 is a strong acid and when in aqueous solution it dissociates completely into hydronium ions or H+ and to HSO4- ions. The sulfuric acid can donate H+ decreasing the pH of a solution. Hope this answers the question.
Explanation:
Geological activity determines geological structures. The prevalent types and forms of tectonic working in a place will control the form of structure that can be found in a terrain.
- In volcanic region, it is common to see volcanic structures of different types such as calderas, strato-volcano etc. These structures are formed by the volcanic activities.
- Also, in a karst topography, we find sink holes, stalactites and stalagmites etc. due to the nature of the geologic activities going on.
- Some sedimentary rocks shows cross bedding due to the environment where they form.
So, geologic activities controls the structure found in an area
