The percentage of tin in alloy is 12.27%

Explanation:

In context to the question asked we have to find out percentage of tin in the alloy

Total elements in all = 114

Total number of carbon elements = 100

Total no of tin particle = 14

Percentage of tin in alloy = Total elements of tin / total elements in alloy x 100

=14/114 x 100

= 12.27%

So, by this we can conclude that there is 12.27% tin in the alloy.

Answer:

∴ Percentage of tin in the alloy is [tex]12.28[/tex]%.

Step-by-step explanation:

• In context to question asked,
• We have to find the percentage of tin in the alloy.
• It is given that, Parts of tin in alloy = [tex]14[/tex]

             Parts of copper in alloy = [tex]100[/tex]

• Total parts of  tin and copper in alloy = [tex]14+100[/tex]

                                                     = [tex]114[/tex]

• Now,

  Percentage of tin in the alloy = [tex]\frac{14}{114} \times 100[/tex]

                                            = [tex]\frac{1400}{114}[/tex]

                                            = [tex]12.28[/tex]%

• ∴ Percentage of tin in the alloy is [tex]12.28[/tex]%.

Answer:

Shylock announces that he will take his pound of flesh from Antonio's heart if Antonio forfeits on his loan. He then tells Tubal to go and meet him later at the synagogue. Shylock again insists that he will have his revenge on Antonio by enforcing the legal contract they have signed.

Answer:

The Duke of Venice is one of the main characters of the story.

He plays the character of a strong man with firm opinions.

He tries to withhold law against all odds.

It is also one of the major reasons that his friends seek help from him whenever they are in trouble.

The other two main characters of the story are Salanio and Salarino.

Explanation:

Answer:

First law of Thermodynamics we have :-

Q= w+ΔU   (1)

where,

Q = Heat supplied to the gas

w = Work done by the gas

ΔU = Change in the internal energy of the gas

Given :-

w= Q/4     (2)

From (1) & (2) we have :-

⟹ΔU= 3Q/4      (3)

Now,

ΔU=  nRΔT/  γ−1    (4)

where,

n = No. of moles of gas  

ΔT = Change in temperature  

R = Universal Gas Constant  

γ = Specific heat ratio  

For a diatomic gas :-

γ=7/5          ( 5)

Using (3), (4) & (5) we get :-

⟹nΔT=  3Q/ 10R       (6)

Also note that :-

Q=nCΔT      (7)

where,  

C = Molar specific heat for the process

So now replace nΔT in (7) by (6) :-

⟹  3QC/  10R    =Q

⟹C=   10R/3
