Answer: 34.5 g of Copper reacts with 70.2 g of silver nitrate according to the following balanced equation: Cu + 2AgNO→ Cu(NO3)2 + 2Ag a) What is the limiting reactant
Explanation:
Cycloalkanes are ring structures with the general formula: CnH(2n). Following are basic rules for naming cycloalkanes.
1. Parent Chain
Use the cycloalkane as the parent chain if it has a greater number of carbons than any alkylsubstituent.
If an alkyl chain off the cycloalkane has a greater number of carbons, then use the alkyl chain as the parent and the cycloalkane as a cycloalkyl-substituent.
2. Numbering the Cycloalkane
When numbering the carbons of a cycloalkane, start with a substituted carbon so that thesubstituted carbons have the lowest numbers (sum).
When two or more different substituents are present, number according to alphabetical order.
3. Halogen Substituents
Halogen substituents are treated exactly like alkyl groups
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!
