Answer:
The answer to your question is: 6 moles of HNO₃
Explanation:
Data
Volume = 25 ml
Concentration = 6 M HNO₃
Diluted 100 ml
Formula
Molarity = # moles / volume
# of moles = Volume x Molarity
Process
# of moles = 0.10 x 6
= 6 moles
Answer:
CuSO4 + Fe -> FeSO4 + Cu
Explanation:
This reaction is a classic example of a redox reaction. I won't go in too deep, but the basic thing is that electrons from the Fe atom go to the Cu2+ ion. Therefore, Fe becomes an ion, and Cu - an electroneutral atom:
Fe + Cu2+ -> Fe2+ + Cu.
Silver is not a very reactive metal and it does not give up its electrons to Cu.
Answer:
a. 123.9°C
b.
c.
Explanation:
Hello, I'm attaching a picture with the numerical development of this exercise.
a. Since the steam is overheated vapour, the specific volume is gotten from the corresponding table. Then, as it became a saturated vapour, we look for the interval in which the same volume of state 1 is, then we interpolate and get the temperature.
b. Now, at 80°C, since it is about a rigid tank (constant volume for every thermodynamic process), the specific volume of the mixture is 0.79645 m^3/kg as well, so the specific volume for the liquid and the vapour are taken into account to get the quality of 0.234.
c. Now,since this is an isocoric process, the heat transfer per kg of steam is computed as the difference in the internal energy, considering the initial condition (showed in a. part) and the final one computed here.
** The thermodynamic data were obtained from Cengel's thermodynamics book 7th edition.
Best regards.
