Which compound contains both sigma and pi bonds

2 answers:

8 0

The difference starts with sigma bonds. Electrons are disabled by nuclear attraction from both bonding nuclei, while within pi bonds, electrons are loosely held in the general proximity of either bonding nucleus. All pi bonds are naturally delocalisable. People are most commonly used to call it “double bond character,” but since it can occur for triple bonds as well as bonding that never even fully constitutes a double bond, stigma character and pi character are more appropriate, in my opinion.

If I initially have a gas at a pressure of 12 atm, volume of 23 liters, and temperature of 200 K, and then I raise the pressure

CaHeK987 [17]

Answer : The volume of gas will be 29.6 L

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 12 atm

$P_2$ = final pressure of gas = 14 atm

$V_1$ = initial volume of gas = 23 L

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = 200K

$T_2$ = final temperature of gas = 300K

Now put all the given values in the above equation, we get the final pressure of gas.

$\frac{12atm\times 23L}{200K}=\frac{14\times V_2}{300K}$

$V_2=29.6L$

Therefore, the new volume of gas will be 29.6 L

Why do substances with weak intermolecular forces form solids at low melting points?

Advocard [28]

To make any substance solid, molecules must come very close to each other. Substances with weak intermolecular forces have weak bonding. Hence to make their molecules come close to each other, we must provide low temperature.

A balloon contains 11.1 g of nitrogen monoxide gas (NO). how many molecules are in the balloon?

grandymaker [24]

The number of molecules that are in balloon are = 2.227 x10^23 molecules

<h3> calculation</h3>

calculate the number of moles of NO

moles = mass/molar mass

molar mass of NO = 14+ 16 = 30 g/mol

moles is therefore= 11.1 g/30g/mol= 0.37 moles

by use of Avogadro's constant that is

1 mole= 6.02 x10^23 molecules

0.37 =? molecules

=(6.02 x10^23 x 0.37 moles)/ 1mole=2.227 x10^23 molecules

As a forensic expert, Jane needs to handle many biological evidence samples simultaneously. What is the basic precaution that sh

madreJ [45]

Answer:

B. use a new pair of gloves for each piece of evidence

Explanation:

When it comes to the basic precautions of handling biological evidence samples, one has to prevent cross contamination. This refers to the<em> transfer of DNA from one evidence to another evidence</em>; thus, it is important for Jane to use a new pair of gloves for each piece of evidence in order to prevent such occurrence.

Wearing of gloves will also <em>prevent Jane's DNA from being implanted into the sample</em>, and it will keep her safe from contracting blood-borne pathogens like those in the saliva, blood or semen.
