Answer:
Final temperature of solution is 27.48
Explanation:
Total volume of mixture = (60.0+60.0) mL = 120.0 mL
We know, density = (mass)/(volume)
So mass of mixture =
Amount of heat released per mol of =
Where, m represents mass , C represents specific heat, represents change in temperature and n is number of moles
As this reaction is an exothermic reaction therefore temperature of mixture will be higher than it's initial temperature.
Let's say final temperature of mixture is T
So,
Here and
Moles of H_{3}PO_{4} are added = = 0.012 moles
So,
or, T = 27.48
So, final temperature of solution is 27.48
Answer:
False
Explanation:
At the end of the 1000 years, Satan will be released, defeated again, and then cast into the lake of fire (Revelation 20:7-10). Then, after a final judgment by God, the end of the world described in 2 Peter 3:10 occurs. The Bible tells us several things about this event.
Since we have to MELT the iron, heat of fusion will be used.
So, energy required = 247 * 500 J
= 123500 J.
Mass (g) / Volume (cm^3) = Density (g/cm^3)
60.4g/ 11.3 cm^3 = 5.35 g/cm^3
d= 5.35 g/cm^3
