explain why the definition of philosophy as the love of wisdom in insufficient?
Answer:
The word “philosophy” literally means the “love” (philo in Greek) of “wisdom” (sophia). So, a philosopher is somebody who loves wisdom. This, of course, leaves us with 2 important questions: What is wisdom? And what does it mean to love wisdom?
The idea of philosophy goes all the way back to ancient Greece. It is said that the philosopher Pythagoras in the 6th century BCE was the 1st to call himself a philosopher—a philosophos, or “lover of wisdom.” In calling himself this, he was not claiming to be wise. Instead, he was merely saying that he was somebody who valued or cherished wisdom.
Later, the philosopher Plato, who lived in the 5th century BCE, explored these ideas in more depth. In a text called the Symposium, Plato claimed that a philosopher was somebody who was “between the wise and the ignorant.” In other words, a philosopher cared about wisdom but also knew that they were ignorant (we will see tomorrow how Plato was influenced in this by his teacher, Socrates).

The 50:50 mixture of aspirin (Lit. MP: 135-136 oC) and 4-bromobenzoic acid (Lit. MP: 252-254 oC) will have the melting point in the range of:______.
Answer:
193.5-195 °C.
Explanation:
Hello!
In this case, since the mixture is 50:50, we can infer that an average may be used to compute the required range; thus, we first compute the the inner limit by using 135 °C and 252 °C:
[tex]\frac{135+252}{2} =193.5\°C[/tex]
And the upper limit:
[tex]\frac{136+254}{2} =195\°C[/tex]
Thus, the average melting point would be around 193.5-195 °C.
Best regards!

a. Compared to nitrogen, the ____________of ethylene makes it more soluble in water.
b. The high solubility of sulfur dioxide can be explained by its ______________
c. Nitric oxide is more soluble than nitrogen and oxygen because of its ______________
d. Compared to oxygen, nitrogen's _____________ makes it more difficult for water molecules to surround the nitrogen molecules.
1. Polarity
2. Ability to react with water
3. Shorter bond length
4. Larger molecular size
Answer:
a. Larger molecular size
b. Ability to react with water
c. Polarity
d. Shorter bond length
Explanation:
Ethene is a larger molecule than oxygen and nitrogen hence it is more soluble than the both other gases .
SO2 dissolves readily in water to yield an acid solution. It is an acid anhydride.
Nitric oxide is a polar compound. It remains very much polar while nitrogen and oxygen are non polar.
Nitrogen is sp hybrized, this leads to a very short bond and does not easily interact with oxygen and nitrogen
Calculate the mass, in grams, of 912 atoms of iron, Fe (1 mol of Fe
has a mass of 55.85 g).
Answer:
8.45 × 10⁻²⁰ g
Explanation:
Step 1: Given data
Number of atoms of Fe (N): 912 atomsMolar mass of Fe (M): 55.85 g/molStep 2: Calculate the mass, in grams, of 1 atom of Fe
We will use Avogadro's number: there are 6.02 × 10²³ atoms of Fe in 1 mole of Fe.
55.85 g/mol × 1 mol/6.02 × 10²³ atom = 9.27 × 10⁻²³ g/atom
Step 3: Calculate the mass corresponding to 912 atoms
9.27 × 10⁻²³ g/atom × 912 atom = 8.45 × 10⁻²⁰ g

Fred is about to order a stack of four pancakes with butter and syrup, but he wonders how much he would need to exercise to burn off the Calories from it. He pulls out his cell phone and finds the nutritional information for the stack of pancakes. He notes that a serving has 181g of carbohydrates, 27g of fat, and 16g of protein. Now, he has to convert these values into Calories.
Running at a pace of 8 minutes per mile burns 14 Calories/minute. How many minutes would he have to run at an 8 minutes per mile pace to bum off the Calories from the stack of pancakes?
Answer:
The correct answer is - 73.64 minutes.
Explanation:
We know that each gram of protein and carbohydrate produces 4 calories of energy whereas fat produces 9 cal energy per gram.
So, the Calories from carbohydrates
= 181 ×4
= 724 Cal
and, 27 g fat produces = 27 × 9 = 243 Cal
and, 16 g protien = 16 × 4 = 64 Cal
so the total energy will be - 243+ 724+ 64 = 1031 Cal
Thus, the time Fred need to run = 1031/14 =73.64 min

In a technique used for surface analysis called auger electron spectroscopy (AES), electrons are accelerated toward a metal surface. These electrons cause the emissions of secondary electrons (called auger electrons) from the metal surface. The kinetic energy of the auger electrons depends on the composition of the surface. The presence of oxygen atoms on the surface results in auger electrons with a kinetic energy of approximately 520 eV .

What is the de Broglie wavelength of one of these electrons?
Answer:
the de Broglie wavelength of one of the electrons is 5.3787 × 10⁻¹¹ m
Explanation:
Given the data in the question;
we know that; ( electron volt ) 1 eV = 1.602 × 10⁻¹⁹ J
so given that Kinetic Energy KE = 520 eV
KE = 520 × 1.602 × 10⁻¹⁹ = 8.3304 × 10⁻¹⁷ J
we know that;
Kinetic Energy = 1/2 × mv²
where m is the electron mass
and mass of electron is 9.109 × 10⁻³¹ kilograms
so
8.3304 × 10⁻¹⁷ = 1/2 × 9.109 × 10⁻¹⁷× v²
v = √[(8.3304 × 10⁻¹⁷) / (1/2 × 9.109 × 10⁻³¹)]
v = 1.3524 × 10⁷ m/s
speed of the electron v = 1.3524 × 10⁷ m/s
now, de Broglie equation;
wavelength λ = h / mv
where h is Planck constant ( 6.626 × 10⁻³⁴ m² kg / s )
so we substitute
wavelength λ = 6.626 × 10⁻³⁴ / ( 9.109 × 10⁻³¹ × 1.3524 × 10⁷)
wavelength λ = 5.3787 × 10⁻¹¹ m
Therefore, the de Broglie wavelength of one of the electrons is 5.3787 × 10⁻¹¹ m

3AgNO3(aq) + FeCl3(aq) → 3AgCl(s) + Fe(NO3), (aq)
Write the balanced net ionic equation for the reaction.
Answer: [tex]3Ag^+(aq)+3Cl^-(aq)\rightarrow 3AgCl(s)[/tex]
Explanation:
Complete ionic equation : In complete ionic equation, all the substance that are strong electrolytes and are represented in the form of ions.
The complete ionic equation will be:
[tex]3Ag^+(aq)+3NO_3^-(aq)+Fe^{3+}(aq)+3Cl^-(aq)\rightarrow 3AgCl(s)+Fe^{3+}(aq)+3NO_3^-(aq)[/tex]
Net ionic equation : In the net ionic equations, we do not not include the spectator ions in the equations.
Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.
In this equation, [tex]Fe^{3+}[/tex] and [tex]NO_3^-[/tex] are the spectator ions.
By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.
The net ionic equation will be:
[tex]3Ag^+(aq)+3Cl^-(aq)\rightarrow 3AgCl(s)[/tex]
Calculate the volume of concentrated HCl (12 M) needed to convert the sodium benzoate back to benzoic acid.
The question is incomplete, the complete question is;
Calculate the volume of concentrated HCL (12 M) needed to convert 1.5 g of sodium benzoate back to benzoic acid.
Answer:
8.33 * 10^-4 L
Explanation:
Equation of the reaction;
C6H5COONa + HCl -------->>>> C6H5COOH + NaCl
Number of moles of sodium benzoate = mass/molar mass
molar mass of sodium benzoate =144.11 g/mol
mass of sodium benzoate = 1.5 g
Number of moles of sodium benzoate = 1.5g/144.11 g/mol
Number of moles of sodium benzoate = 0.01 moles
Since the reaction is 1:1, 0.01 moles of HCl reacted.
but;
n = CV
n = number of moles
C = concentration
V = volume
V = n/C
V = 0.01 moles/12 M
V = 8.33 * 10^-4 L
What is the half‑life of an isotope that decays to 25% of its original activity in 85.8 h
Answer:
42.9 h
Explanation:
From the question given above, the following data were obtained:
Original amount (N₀) = 100%
Amount remaining (N) = 25%
Time (t) = 85.8 h
Half-life (t½) =?
Next, we shall determine the number of half-lives that has elapse. This can be obtained as follow:
Original amount (N₀) = 100%
Amount remaining (N) = 25%
Number of half-lives (n) =?
N = 1/2ⁿ × N₀
25 = 1/2ⁿ × 100
Cross multiply
25 × 2ⁿ = 100
Divide both side by 25
2ⁿ = 100/25
2ⁿ = 4
Express 4 index form with 2 as the base
2ⁿ = 2²
n = 2
Thus, two half-lives has elapsed.
Finally, we shall determine the half-life of the of the isotope. This can be obtained as follow:
Time (t) = 85.8 h
Number of half-lives (n) = 2
Half-life (t½) =?
n = t / t½
2 = 85.8 / t½
Cross multiply
2 × t½ = 85.8
Divide both side by 2
t½ = 85.8 / 2
t½ = 42.9 h
Thus, the half-life of the of the isotope is 42.9 h
