Which of the following compounds is likely to make the best conductor when
dissolved in water?
a. SO2
b. C6H1206
c. KBr
d. CO
Answer:
c. KBr .
Explanation:
Hello!
In this case, since electrolytes are substances that are able to carry electric current in the form of electrons via ions, those that are ionic are said to have the greatest capacity to conduct the electricity; in such a way, since SO2, C6H12O6 and CO are non-ionic molecules but covalent, they are not good conductor, therefore the best conductor would be c. KBr as it is an ionic compound due to the electronegativity of the K-Br bond.

The pH of a sample of blood is 7.4, while gastric juice is pH 1.4. The blood sample has: Group of answer choices 0.189 times the [H ] as the gastric juice. 6 times lower [H ] than the gastric juice. one million times lower [H ] than the gastric juice 5.29 times lower [H ] than the gastric juice. 6000 times lower [H ] than the gastric juice.
Answer:
The blood sample has [H⁺] that is one million times lower than the [H⁺] of gastric juice.
Explanation:
To know the the correct answer to the question, we obtained obtained the hydrogen ion concentration [H⁺] of the blood and gastric juice. This can be obtained as follow:
For Blood sample:
pH = 7.4
Concentration of Hydrogen ion for blood [H⁺]₁ =?
pH = – Log [H⁺]₁
7.4 = – Log [H⁺]₁
Divide both side by –1
– 7.4 = Log [H⁺]₁
Take the antilog of – 7.4
[H⁺]₁ = Antilog (–7.4)
[H⁺]₁ = 3.98×10¯⁸ M
Thus, the concentration of Hydrogen ion for blood [H⁺]₁ is 3.98×10¯⁸ M
For Gastric juice:
pH = 1.4
Concentration of Hydrogen ion for gastric juice [H⁺]₂ =?
pH = – Log [H⁺]₂
1.4 = – Log [H⁺]₂
Divide both side by –1
– 1.4 = Log [H⁺]₂
Take the antilog of – 1.4
[H⁺]₂ = Antilog (–1.4)
[H⁺]₂ = 3.98×10¯² M
Thus, the concentration of Hydrogen ion for gastric juice [H⁺]₂ is 3.98×10¯² M
Finally, we shall compare the hydrogen ion concentration [H⁺] of the blood and gastric juice. This can be obtained as follow:
Concentration of Hydrogen ion for blood [H⁺]₁ = 3.98×10¯⁸ M
Concentration of Hydrogen ion for gastric juice [H⁺]₂ = 3.98×10¯² M
[H⁺]₁ / [H⁺]₂ = 3.98×10¯⁸ / 3.98×10¯²
[H⁺]₁ / [H⁺]₂ = 1×10¯⁶
Cross multiply
[H⁺]₁ = [H⁺]₂ × 1×10¯⁶
[H⁺]₁ = [H⁺]₂ / 1000000
From the calculations made above, the blood sample has [H⁺] that is one million times lower than the [H⁺] of gastric juice.
Bond length is the distance between the centers of two bonded atoms. On the potential energy curve, the bond length is the internuclear distance between the two atoms when the potential energy of the system reaches its lowest value. Consider that the atomic radius (sometimes called the covalent or bonding atomic radius) of an element is defined as one-half the distance between the bonded atoms in a homonuclear diatomic molecule. Actual bond lengths in molecules are determined experimentally by such methods as X-ray diffraction and microwave spectroscopy. However, these atomic radii values can be used to give an estimate of the upper limit of bond length in other (heteronuclear) molecules. Given that the atomic radii of H and Br are 37.0 pm and 115 pm , respectively, predict the upper limit of the bond length of the HBr molecule.
Answer:
152 pm
Explanation:
According to the question, we can estimate the bond length from the given values of the atomic radii. This now is the upper limit of the bond length for the molecule.
Since we have that;
Atomic radius of H= 37.0 pm
Atomic radius of Br = 115.0 pm
Bond length = Atomic radius of H + Atomic radius of Br
Bond length = 37.0 pm + 115.0 pm
Bond length = 152 pm

Suppose two students grab an end of a rope. Both shake a rope once in a upward direction to create crests traveling at each other. What would you see when crests meet? What type of interference does this show?
Answer:
This creates destructive interference.
Explanation:
When the two ends meet they will cancel each other out.
Both students are shaking the rope in the upward direction. Hence their crest will meet up and form the constructive interference pattern. The intensity of the increases.
What is constructive interference ?When two waves moves in phase, their crest or troughs add up and the amplitude of the wave increases. This phenomenon is called constructive interference.
If the two waves are passing out of phase to each other then they undergo destructive interference. The amplitude of the destructive interference pattern reduces from their initial values.
Here, both students are shaking the rope in the upward direction. Thus, they are in moving in phase. Hence their crest will meet up and form the constructive interference pattern. The intensity of the increases.

When 271. mg of a certain molecular compound X are dissolved in 25.0g of benzene C6H6, the freezing point of the solution is measured to be 0.5°C. Calculate the molar mass of X.
If you need any additional information on benzene, use only what you find in the ALEKS Data resource. Also, be sure your answer has a unit symbol, and is rounded to 2 significant digits.
molal freezing point depression constant (Kf)
°C·kg·mol−1 of benzene is 5.07
Answer:
11g/mol is the molar mass of X
Explanation:
The freezing point depression occurs in a solvent by the addition of a solute. The equation is:
ΔT = Kf*m*i
Where ΔT is change in freezing point (5.5°C - 0.5°C = 5.0°C)
Freezing point of benzene is 5.5°C
Kf is molal freezing point depression of benzene (5.07°C*kg/mol)
m is molality of the solution in moles/kg of solvent
And i is Van't Hoff factor (1 for all solutes dissolved in benzene)
Replacing to solve molality:
5.0°C = 5.07°C*kg/mol*m*1
0.986mol / kg = molality
As the mass of the solvent is 25.0g = 0.025kg:
0.025kg * (0.986mol/kg) = 0.0247 moles

A chemist is studying the rate of the Haber synthesis: N2 + 3H2 2NH3
Starting with a closed reactor containing 1.25 mol/L of N2 and 0.50 mol/L of H2, the chemist finds that the H2 concentration has fallen to 0.25 mol/L in 44 seconds.What is the N2 concentration after 44 seconds?
Answer:
1.17 M
Explanation:
Step 1: Write the balanced equation
N₂ + 3 H₂ ⇒ 2 NH₃
Step 2: Calculate the rate of disappearance of H₂
We will use the following expression.
rH₂ = - Δ[H₂]/t = - (0.25 M - 0.50 M)/44 s = 0.0057 M/s
Step 3: Calculate the rate of disappearance of N₂
The molar ratio of N₂ to H₂ is 1:3.
0.0057 mol H₂/L.s × 1 mol N₂/3 mol H₂ = 0.0019 mol N₂/L.s
Step 4: Calculate the final concentration of N₂
We will use the following expression.
[N₂] = [N₂]₀ - rN₂ × t
[N₂] = 1.25 mol/L - 0.0019 mol/L.s × 44 s
[N₂] = 1.17 M
In 1932, Robert Emerson and William Arnold used isolated spinach chloroplasts to determine that it requires 2,400 chlorophyll molecules to generate one O2 molecule. Based on this number and your understanding of where and how O2 is formed in chloroplasts, if a spinach chloroplast absorbs 720 photons, then how many resonance energy transfer reactions occur in the light-harvesting complexes and how many O2 molecules are formed
Answer:
There will be 216,000 energy transfer reactions
90 [tex]O_{2}[/tex] molecules will be formed
Explanation:
since 2400 chlorophyll molecules = ( 1 ) [tex]O_{2}[/tex] molecule
hence there will be 8 photons absorbed in this process
for 720 absorbed photons
The number of [tex]O_{2}[/tex] molecules formed = 720 / 8 = 90 molecules of [tex]O_{2}[/tex] molecule formed
Total number of resonance energy transfer reactions
( 1 ) [tex]O_{2}[/tex] molecule = 2400 molecules
hence 90 molecules of [tex]O_{2}[/tex]
= 2400 molecules * 90 molecules
= 216000 energy transfer reactions

The first red (632.8 nm) Helium Neon gas laser was reported by White and Rigdon from Bell Labs in 1962. The laser was a discharge tube that was 1.2 m long with a 7 mm diameter. A He-Ne ratio of 10:1 was used with a total pressure of 0.00092 atm. This is a really low pressure with a really small amount of He and Ne. We want to try making a new laser with the same discharge tube with 5 mol Helium and 1 mol Neon. For the new laser with 5 mol He and 1 mol Ne, calculate the following quantities. Assume room temperature (298.15 K) and that the gasses are ideal.
a. What is the total volume (cm^3)?
b. What is the mole fraction of He?
c. What is the mole fraction of Ne?
d. What is the partial pressure of He (in atm)?
e. What is the partial pressure of Ne (in atm)?

b) Mole[tex]_{fraction}[/tex] (He) = 0.8333
c) Mole[tex]_{fraction}[/tex] (Ne) = 0.1666
d) Partial Pressure P[tex]_{He}[/tex] = 2648.68 atm
e) Partial Pressure P[tex]_{Ne}[/tex] = 529.73 atm
f) total pressure of the new laser tube = 3178.41 atm
Explanation:
Given that;
height of of discharge tube h = 1.2 m = 1.2 × 100 = 120cm
diameter of the tube D = 7 mm = 0.7cm
Radius = D/2 = 0.7/2 = 0.35 cm
a) What is the total volume (cm³)?
Volume = πr²h
we substitute
Volume = π × (0.35)² × 120
Volume = 46.18 cm³
b) What is the mole fraction of He?
Mole fraction of Helium will be;
Mole[tex]_{fraction}[/tex] (He) = Moles of He / Total Moles ( He + Ne)
given that; 5 mol He and 1 mol Ne
Mole[tex]_{fraction}[/tex] (He) = 5 / ( 5 + 1 )
Mole[tex]_{fraction}[/tex] (He) = 5 / 6
Mole[tex]_{fraction}[/tex] (He) = 0.8333
c) What is the mole fraction of Ne?
Mole fraction of Neon will be;
Mole[tex]_{fraction}[/tex] (Ne) = Moles of Ne / Total Moles ( He + Ne)
given that; 5 mol He and 1 mol Ne
Mole[tex]_{fraction}[/tex] (Ne) = 1 / ( 5 + 1 )
Mole[tex]_{fraction}[/tex] (Ne) = 1 / 6
Mole[tex]_{fraction}[/tex] (Ne) = 0.1666
d) d. What is the partial pressure of He (in atm)?
using ideal gas equation;
P[tex]_{He}[/tex] = nRT/V
where n is number or amount of moles( 5 )
R is the universal gas constant ( 0.08205 L-atm.mol⁻¹K⁻¹
T is temperature ( 298.15 K)
And V is the volume; ( 46.18 cm³ = 46.18/1000 = 0.04618 L )
so we substitute
P[tex]_{He}[/tex] = (5 × 0.08205 × 298.15) / 0.04618
P[tex]_{He}[/tex] = 122.316 / 0.04618
P[tex]_{He}[/tex] = 2648.68 atm
e) What is the partial pressure of Ne (in atm)?
P[tex]_{Ne}[/tex] = (1 × 0.08205 × 298.15) / 0.04618
P[tex]_{Ne}[/tex] = 24.463 / 0.04618
P[tex]_{Ne}[/tex] = 529.73 atm
f) What is the total pressure of the new laser tube (in atm)?
total pressure of the new laser tube will be;
= P[tex]_{He}[/tex] + P[tex]_{Ne}[/tex]
= 2648.68 atm + 529.73 atm
= 3178.41 atm
total pressure of the new laser tube = 3178.41 atm
