what are the functional groups in tramadol

We are given:

Wavelength of Green light (λ) = 531 nm  OR   531 * 10⁻⁹ m

Speed of light (c) = 3* 10⁸ m/s

Solving for the Frequency of the wave:

We know the relation:

c = νλ    

(where ν is the frequency, c is the speed of light and λ is the wavelength)

3*10⁸ = ν*(531*10⁻⁹)

ν = 3*10⁸ / 531*10⁻⁹                  [dividing both sides by the wavelength]

ν = 3*10⁸*10⁹ / 531                   [ since a⁻¹ = 1/a]

ν = 3*10¹⁷ / 531                         [ since mᵃ * mᵇ = mᵃ⁺ᵇ]

ν = 10¹⁷ / 177

ν = 1000 * 10¹⁴ / 177                 [we split the numerator to simplify]

ν = 5.65 * 10¹⁴

Hence, the frequency of Green light is 5.65 * 10¹⁴ Hz

Answer:

f = 5.6×10¹⁴ Hz  

Explanation:

Given data:

Wavelength of green light = 531 nm (531×10⁻⁹ m)

Frequency of green light = ?

Solution:

Formula;

Speed of wave = wavelength × frequency

Speed of wave = 3.00×10⁸ m/s

by putting vales,

3.00×10⁸ m/s = 531×10⁻⁹ m × f

f = 3.00×10⁸ m/s / 531×10⁻⁹ m

f  = 0.0056×10¹⁷ s⁻¹

f = 5.6×10¹⁴ Hz    (Hz = s⁻¹)

Answer:

When 45 gram of total mass of reactant react 45 gram of product will also produced

Explanation:

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

For example:

In given photosynthesis reaction:

6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

In a similar way,

2Na + 2H₂O    →  2NaOH + H₂

45 g         =        45 g

when 45 gram of total mass of reactant react 45 gram of product will also produced. (2NaOH + H₂ = 45 g)

Answer: 1.95 g of oxygen is present.

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

[tex]p_{total}=p_{methane}+p_{oxygen}[/tex]

Given : [tex]p_{total}[/tex] =total pressure of gases = 727 mm Hg

[tex]p_{methane}[/tex] = partial pressure of methane = 571 mm Hg

[tex]p_{oxygen}[/tex] = partial pressure of oxygen = ?

[tex]727=571+p_{oxygen}[/tex]  

[tex]p_{oxygen}=156mmHg[/tex]

Also [tex]p_{oxygen}=x_{oxygen}\times p_{total}[/tex]

Given : 3.62 g of methane is present

moles of methane = [tex]\frac{\text{Given mass}}{\text {Molar mass}}=\frac{3.62g}{16g/mol}=0.226moles[/tex]

[tex]x_{oxygen}[/tex] = mole fraction of oxygen  

=[tex]\frac{\text {moles of oxygen}}{\text {total moles}}=\frac{y}{y+0.226}[/tex]

[tex]156=\frac{y}{y+0.226}\times 727[/tex]

[tex]y=0.061[/tex]

mass of oxygen = [tex]moles\times {\text {Molar mass}}=0.061\times 32=1.95g[/tex]

Thus 1.95 g of oxygen is present.

Answer:

1.02 × 10⁶ g

Explanation:

Step 1: Given data

Step 2: Convert "V" to L

We will use the conversion factor 1 m³ = 1000 L.

5400 m³ × 1000 L/1 m³ = 5.400 × 10⁶ L

Step 3: Convert "P" to atm

We will use the conversion factor 1 atm = 101325 Pa.

1.10 × 10⁵ Pa × 1 atm / 101325 Pa = 1.09 atm

Step 4: Calculate the moles of He (n)

We will use the ideal gas equation.

P × V = n × R × T

n = P × V / R × T

n = 1.09 atm × 5.400 × 10⁶ L / 0.08206 atm.L/mol.K × 280 K

n = 2.56 × 10⁵ mol

Step 5: Calculate the mass of He (m)

We will use the following expression.

m = n × M

m = 2.56 × 10⁵ mol × 4.002 g/mol

m = 1.02 × 10⁶ g

Thus the above response is correct.

Answer:

Mass = 8.46 g

Explanation:

Given data:

Mass of water produced = ?

Mass of glucose = 20 g

Mass of oxygen = 15 g

Solution:

Chemical equation:

C₆H₁₂O₆ + 6O₂     →   6H₂O + 6CO₂

Number of moles of glucose:

Number of moles = mass/molar mass

Number of moles = 20 g/ 180.16 g/mol

Number of moles = 0.11 mol

Number of moles of oxygen:

Number of moles = mass/molar mass

Number of moles = 15 g/ 32 g/mol

Number of moles = 0.47 mol

now we will compare the moles of water with oxygen and glucose.

               C₆H₁₂O₆           :            H₂O

                   1                   :              6

                 0.11                :           6/1×0.11 = 0.66

                   O₂               :            H₂O

                   6                   :              6

                 0.47                :           0.47

Less number of moles of water are produced by oxygen thus it will limit the yield of water and act as limiting reactant.

Mass of water produced:

Mass = number of moles × molar mass

Mass = 0.47 mol  ×18 g/mol

Mass = 8.46 g

Al2(SO4)3 =

Al2 S3 O12

Total atom :

Al = 2

S = 3

O = 12

Answer:

4 Al(s) + 3 O₂(g) ⇒ 2 Al₂O₃(s)

Explanation:

Let's consider the unbalanced molecular equation when aluminum metal and oxygen gas combine to produce aluminum oxide. This is a combination reaction.

Al(s) + O₂(g) ⇒ Al₂O₃(s)

We can balance O  atoms by multiplying O₂ by 3 and Al₂O₃ by 2.

Al(s) + 3 O₂(g) ⇒ 2 Al₂O₃(s)

Finally, we multiply Al by 4 to get the balanced equation.

4 Al(s) + 3 O₂(g) ⇒ 2 Al₂O₃(s)

Answer:

Ti

Explanation:

Ti is titanium and does not share any similar properties with the likes of Si, silicon and At, astatine.

Answer:

the pressure = 1937mmhg using standered unit of volume

Solution :

From Fick's law:

[tex]$\frac{D_{AB}}{\Delta z } \times (C_{A1}-C_{A2})=N_a$[/tex]

Mass balance: Exits = Accumulation

[tex]-N_A A = \frac{dm}{dt}[/tex]

[tex]-N_A A = \frac{dVp}{dt}[/tex]

[tex]-N_A A = \frac{dV}{dt}p[/tex]

[tex]-N_A A = \frac{dhA}{dt}[/tex]

[tex]-N_A A = \frac{dh}{dt} \times Ap[/tex]

From the last step, area cancels out and thus leaves :

[tex]-N_A = \frac{dh}{dt} \times p[/tex]

So now we can substitute the [tex]$N_A$[/tex] by the Fick's law

[tex]$\frac{D_{AB}}{\Delta z } \times (C_{A1}-C_{A2})=\frac{dh}{dt} p$[/tex]

Substituting the values we get

[tex]$=\frac{-4 \times 10^{-13}}{0.0001} \times (3 \times 10^{26} - C_{A2}) = \frac{dh}{dt} \times 2.46$[/tex]

[tex]$=-4 \times 10^{-9} \times( 3 \times 10^{26} - C_{A2}) = 0.0001 \times 2.46$[/tex]

[tex]$= -7800 \times 4 \times 10^{-9} \times (3 \times 10^{26}-C_{A2})=0.000246$[/tex][tex]$=-(3 \times 10^{26}-C_{A2}) = 7.8846 \times 100 \times \frac{1}{69.62} \times 6.022 \times 10^{23}$[/tex]

[tex]$C_{A2} = 6.85 \times 10^{28} \ \text{ boron atoms} /m^3$[/tex]

Answer:

choice 3

Explanation:

Hydrogen bonding occurs when a H is bonded to a highly electronegative atom like F. Towards the upper right corner, most atoms have high electronegativity and small atomic radii, according to periodic trends.

Please give thanks :)

Hydrogen is covalently bonded to an element that has a small atomic radius and high electronegativity.  

• An intermolecular attractive force in which an atom of hydrogen, which is bonded covalently to a small, highly electronegative atom is known as a hydrogen bond.  

• Hydrogen bonds are very strong in comparison to other dipole interactions.  

• A typical hydrogen bond exhibits a strength of about 5 percent of that of a covalent bond.  

• Hydrogen bonding takes place only in molecules where hydrogen bonding is bonded covalently to one of the three elements, that is, oxygen, fluorine, or nitrogen.  

Thus, correct answer is option 3.
