Chuck wants to know how many electrons in an atom are not paired up. Which model would be best for Chuck to writeout?
a set of quantum numbers for the last electron in the atom
a configuration with numbers, letters, and superscripts
a dot structure of the atom
an orbital notation of the atom

Answers

Answer:

D. an orbital notation of the atom

Explanation:

Orbital notiation uses lines and arrows to show shells, subshells, and orbitals for electrons in an atom. Since it shows arrows being paired up in this diagram it would be the best model for Chuck to use.

On Edgenuity2020, the answer is D) an orbital notation of the atom

How many moles of chlorine, cl, are there in 8 moles of carbon tetrachloride, ccl4?

Answers

Moles are the amount of substance

the break down of CCl₄ is as follows

CCl₄ --> C + 4 Cl

in the compound CCl₄ - 1 mol of CCl₄ contains 4 mol of Cl

so for every 1 mol of CCl₄ there are 4 mol of Cl

then in 8 mol of CCl₄ - there are 4 x 8 = 32 mol of Cl

so 8 mol of CCl₄ contains 32 mol of Cl

answer is 32 mol of Cl

\boxed{{\text{32 moles}}} of chlorine are present in 8 moles of {\text{CC}}{{\text{1}}_{\text{4}}} .

Further Explanation:

Mole is a measure of the amount of substance. It is defined as the mass of a substance that has the same number of fundamental units as there are atoms in 12 g of carbon-12. Such fundamental units can be atoms, molecules or formula units.

In {\text{CC}}{{\text{l}}_4} , both carbon and chlorine are non-metals. Carbon has four valence electrons whereas chlorine has seven valence electrons. Both share two electrons with each other and a single covalent bond is formed between a carbon and a chlorine atom. So carbon forms four single bonds with four chlorine atoms in order to complete its octet and the octet of chlorine is also fulfilled. This bond is formed due to sharing of the electrons and therefore {\text{CC}}{{\text{l}}_4} is a covalent compound. (Refer to the attached image)

{\text{CC}}{{\text{l}}_4} is a covalent compound. So 1 mole of  {\text{CC}}{{\text{1}}_{\text{4}}} contains 1 mole of carbon and 4 moles of Cl.

Number of moles of Cl in 1 mole of {\text{CC}}{{\text{l}}_4} = 4

So the number of moles of Cl in 8 moles of {\text{CC}}{{\text{l}}_4} is calculated as follows:

\begin{aligned}{\text{Moles of Cl}}&=\left({8\;{\text{mol}}\;{\text{CC}}{{\text{l}}_4}}\right)* \left({\frac{{4\;{\text{mol}}\;{\text{Cl}}}}{{1\;{\text{mol}}\;{\text{CC}}{{\text{l}}_4}}}}\right)\n &=\boxed{32\;{\text{mol}}}\n\end{gathered}

So 8 moles of {\mathbf{CC}}{{\mathbf{l}}_{\mathbf{4}}}  contain 32 moles of Cl.

Which compound has the strongest hydrogen bonding between its molecules? 1. HBr 2. HF 3. HCl 4. HI

Answers

You can compare the strength of the hydrogen bonding by comparing the electronegativities of the other elements. All the four elements, Br, F, Cl and I belong to the same group in the periodic table: group 17 named halogens. Then the kind of bonding they form is similar: polar covalent. You must know the trend of the electronegativities in the periodic table. Electronegativity decrease when you down across a group. Then the electronegativity of F is the higher of the group (indeed, it is the highest of all the 118 elements) . The higher the electronegativity the stronger the attraction that the halogen attracts the electrons and the stronger the hydorgen bonding. Then, the conclusion is that HF has the strongest hydrogen bonding.
The correct answer is HF
