Answer:

The 2s and 3p orbitals would have more nodes than 1s and 2p orbitals.

p orbitals would have same shape, but 3p would be larger

s orbitals would have same shape, but 2s would be larger

The stockroom has provided you with a 1.70 MM stock solution of NaCl NaCl. What volume of this stock solution would be required

bearhunter [10]

Answer: The volume of stock NaCl solution needed is 23 mL

Explanation:

To calculate the molarity of the diluted solution, we use the equation:

$M_1V_1=M_2V_2$

where,

$M_1\text{ and }V_1$ are the molarity and volume of the stock NaCl solution

$M_2\text{ and }V_2$ are the molarity and volume of diluted NaCl solution

We are given:

$M_1=1.70M\\V_1=?mL\\M_2=0.170M\\V_2=230mL$

Putting values in above equation, we get:

$1.70\times V_1=0.170\times 230\\\\V_1=\frac{0.170\times 230}{1.70}=23mL$

Hence, the volume of stock NaCl solution needed is 23 mL

Which of the following statements about organic chemistry is correct? Be careful, there may only be one word incorrect.

Leokris [45]

In "condensed structural formula" each carbon atom and its attached hydrogen atoms are written in group in the linear form is correct about organic chemistry.

Option B

Explanation:

"condensed structural formula" is a method of writing or presenting organic structures in line of text. It presents all the atoms, but excludes the vertical bonds and all the horizontal single bonds. In condensed structural formula, or we can say semi-structural formula, covalent bonds are not always presented or shown. When the formula or representation is written in line with covalent bonds being shown, then it is referred to as linear formula. For example- the condensed structural formulas of ethane, propane, and ethanol is written as follows:-

$\mathrm{CH}_{3} \mathrm{CH}_{3},\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{3},\text { and } \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH}$

Apart from these Statement, all others are false because they do not have any logic with respect to organic chemistry.

How does the energy of an electron change when the electron moves closer to the nucleus?

tankabanditka [31]

It increases. B.

Close to the nucleus are high energy levels, because of the pull of the nucleus. But farther away from the nucleus, the electrons there are of low energy level.
