The double bonds in an aromatic ring are not fixed in position as in an alkene. The electrons are considered to be ____ and are delocalized around the ring.
Answers
Answer: The double bonds in an aromatic ring are not fixed in position as in an alkene. The electrons are considered to be in conjugation and are delocalized around the ring.
Explanation:
Chemical compounds that have conjugated planar ring systems where there are delocalized pi-electron clouds are present in place of individual alternate and single bonds.
This means that electrons present in a double bond of alkene are in conjugation.
Therefore, we can conclude that the double bonds in an aromatic ring are not fixed in position as in an alkene. The electrons are considered to be in conjugation and are delocalized around the ring.

a. Less oxygen is available at higher altitudes.
b. More oxygen is available at higher altitudes.

Answer: less oxygen available at higher altitudes
Explanation:
The higher in elevation you get, the lower the air pressure, allowing oxygen atoms to spread out farther, therefore making available oxygen less.

Can someone double check my work? (Ideal Gas Law Equation)
I am solving for the amount of moles in two gases.
For one, it was 4.75mL at 0.5C (273.65K) and 1.2atm.
n=(1.2*4.75)/(0.0821/273.65)=(5.7/22.456)=0.25361653 moles
For the other gas, it was 4.6mL at 0.5C and 1.2atm.
n=(1.2*4.6)/(0.0821/273.65)=(5.52/22.456)=0.24581403 moles

If 0.0015 moles of NaOH is dissolved in 11 L of water, what is the pH of the
solution?
Answers
Answer:
pH = 10.15
Explanation:
NaOH is a strong base so it dissolves completely.
Calculate your [OH-] first by dividing the moles of OH- by the volume.
0.0015 mol OH- / 11 L = 0.00014
Then, calculate the pOH:
pOH = -log[OH-] = -log(0.00014) = 3.85
pOH + pH = 14, so pH = 14 - pOH = 14 - 3.85 = 10.15

What is the mass of an atom with 8 protons, 8 electrons, and 8 neutrons?
Answers
Answer:An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999.
Explanation:
The mass of the atom with 8 protons, 8 electrons, and 8 neutrons would be approximately 16 atomic mass units as the number of electrons has an almost negligible contribution to the mass of the atom.
What is atomic mass?It is the sum of the mass of all the protons as well as the neutrons that are present inside the nucleus.
Atomic mass = total number of protons present in the nucleus + total number of neutrons present in the nucleus of an atom,
As given in the problem we have to find the atomic mass of the atom with eight protons, eight electrons, and eight neutrons,
This given specified atom clearly represents the oxygen atom as it has eight electrons protons and neutrons each.
Thus, the atomic mass of the given atom would be 16.

Which of the following chemical equations follows the law of conservation of mass?
Answers
Answer:
The third choice
Explanation:
The law of conservation of mass tells us that the mass of the reactants and products in a chemical reaction will be equal to one another. Equations follow the law of conservation of mass when they are balanced, which means that they have the same number and type of atoms on each side.
When individual atoms are counted, the third choice has the same number and type of atoms on each side: 1 gallium, three cesium and three fluorine.

What is empirical formula?The easiest whole-number proportion of the numerous elements in a molecule is represented by an empirical formula.
Calculation of empirical formula
Given data:
C = 11.0 g
H = 4.5 g
The atomic mass of C = 12
The atomic mass of H = 1
Now, divide the mass by atomic mass.
1) For carbon atom= 11 / 12 =0.91
2) For hydrogen atom = 4.5 / 1=4.5
Now, divide the lowest term by the obtaining whole number.
1) For carbon atom = 11/ 0.91 = 12
2) For hydrogen atom = 4.5/0.91 = 5
Therefore, the empirical formula will be C2H,

An industrial synthesis of urea obtains 87.5 kg of urea upon reaction of 68.2 kg of ammonia with excess carbon dioxide. Determine the theoretical yield of urea and percent yield for the reaction.
Answers
Answer:
The theoretical yield of urea = 120.35kg
The percent yield for the reaction = 72.70%
Explanation:
Lets calculate -
The given reaction is -
[tex]2NH_3(aq)+CO_2[/tex] →[tex]CH_4N_2O(aq)+H_2O (l)[/tex]
Molar mass of urea [tex]CH_4N_2O[/tex]= 60g/mole
Moles of [tex]NH_3[/tex] = [tex]\frac{62.8kg/mole}{17g/mole}[/tex] (since [tex]Moles=\frac{mass of substance}{mass of one mole}[/tex])
= 4011.76 moles
Moles of [tex]CO_2[/tex] = [tex]\frac{105kg}{44g/mole}[/tex]
= [tex]\frac{105000g}{44g/mole}[/tex]
= 2386.36 moles
Theoritically , moles of [tex]NH_3[/tex] required = double the moles of [tex]CO_2[/tex]
but , [tex]4011.76<2\times 2386.36[/tex] , the limiting reagent is [tex]NH_3[/tex]
Theoritical moles of urea obtained = [tex]\frac{1 mole CH_4N_2O}{2mole NH_3}\times4011.76 mole NH_3[/tex]
= [tex]2005.88mole CH_4N_2O[/tex]
Mass of 2005.88 mole of [tex]CH_4N_2O[/tex] =[tex]2005.88 mole \times\frac{60g CH_4N_2O}{1mole CH_4N_2O}[/tex]
= 120352.8g
[tex]120352.8g\times \frac{1kg}{1000g}[/tex]
= 120.35kg
Therefore , theroritical yeild of urea = 120.35kg
Now , Percent yeild = [tex]\frac{87.5kg}{120.35kg}\times100[/tex]
72.70%
Thus , the percent yeild for the reaction is 72.70%
