Answer:
Explanation:
Hello,
Clausius Clapeyron equation is suitable in this case, since it allows us to relate the P,T,V behavior along the described melting process and the associated energy change. Such equation is:
As both the enthalpy and volume do not change with neither the temperature nor the pressure for melting processes, its integration turns out:
Solving for the enthalpy of fusion we obtain:
Finally the entropy of fusion is given by:
Best regards.
nobody can say it is uncertain but in my opinion it will grow quickly in the next 10 years
Explanation: You cannot be convicted of a crime without evidence. You cannot be convicted of a state crime. You cannot be convicted of a federal crime. If there is no evidence against you, under the law, it simply is not possible for the prosecutor's office to obtain a conviction at trial. So, when you do have evidence it is really impossible to not get convicted unless the judge truly believes your side of the story and declares you not guilty.
I hope this helped :) If not i'm sorry!
Answer:
The answer to your question is 3.5 moles of H₂
Explanation:
Data
moles of H₂ = ?
moles of Zn = 3.5 moles
moles of HCl = excess
Process
1.- Write the balanced chemical reaction
Zn + 2HCl ⇒ ZnCl₂ + H₂
Reactants Elements Products
1 Zn 1
2 Cl 2
2 H 2
2.- Use the coefficients of the balanced reaction to calculate the moles of H₂
1 mol of Zn ----------------- 1 mol of H₂
3.5 moles of Zn ------------- x
x = (3.5 x 1)/1
x = 3.5 moles of H₂
