1. Draw the condensed structural formula of sodium benzoate showing all charges, atoms including any lone pairs in the side chai

n functional group, and all sigma and pi bonds.
2. Draw the condensed structural formula of benzoic acid showing all atoms including any lone pairs in the side chain functional group, and all sigma and pi bonds. Indicate the acidic hydrogen.
3. Draw the condensed structural formula of tetrahydrofuran (THF) showing all heteroatoms plus their lone pairs and all sigma and pi bonds.

The structures are shown in the image attached.

Since the question requires that all the lone pairs, formal charges and sigma and pi bonds should be shown, then the simple condensed structural formula becomes insufficient in this case.

I have attached images of the structural formula of sodium benzoate (image 1), benzoic acid (image 2)  and tetrahydrofuran (image 3).

All the formal charges, lone pairs as well as sigma and pi bonds are fully shown.

Copper has two naturally occurring isotopes. Cu−63 has a mass of 62.939 amu and relative abundance of 69.17%.
fiasKO [112]
The answer is 64.907 amu.

The atomic mass of an element is the average of the atomic masses of its isotopes. The relative abundance of isotopes must be taken into consideration, therefore:
atomic mass of copper = atomic mass of isotope 1 * abundance 1 + atomic mass of isotope 2 * abundance 2

We know:
atomic mass of copper = 63.546 amu
The atomic mass of isotope 1 is: 62.939 amu
The abundance of isotope 1 is: 69.17% = 0.6917
The atomic mass of isotope 1 is: x
The abundance of isotope 2: 100% - 69.17% = 30.83% = 0.3083

Thus:
63.546 amu = 62.939 amu * 0.6917 + x * 0.3083
63.546 <span>amu = 43.535 amu + 0.3083x
</span>⇒ 63.546 amu - 43.535 amu = 0.3083x
⇒ 20.011 amu = 0.3083x
   ⇒ x = 20.011 amu ÷ 0.3083 = 64.907 amu

15 moles of an ideal gas at STP has a volume of ____liters
S_A_V [24]

Answer:

A. 336 L

Explanation:

STP is 0 °C and 1 bar.

At STP, the molar volume of a gas is 22.71 L.

Volume = 15 mol × 22.71 L/mol

Volume = 341 L

===============

The above answer is not in your list of options.

It appears that you are using the <em>OLD</em> (pre-1982) definition of STP, at which the molar volume of a gas is 22.4 L.

Then

V = 15 mol × 22.4 L/mol = 336 L

Which of the following does not describe a physical property of iron?
garik1379 [7]

Answer:

B

Explanation:

Iron becomes liquid when we heat it to a temperature of 1535° C this is it's melting point. If we further heat the liquid to 3,000° C it boils; iron is a gas above this temperature.
