Yeas, the reaction is balanced
Answer:
See the answer below
Explanation:
<em>The correct answer would be that the solute particles lower the solvent's vapor pressure, thus requiring a higher temperature to cause boiling.</em>
Dissolving a solute particle in a solvent leads to a decrease in the vapor pressure of the solvent above the resulting solution when compared to the pure solvent. The lower the vapor pressure of a liquid, the higher the temperature required for the liquid to boil and vice versa. Hence, a higher temperature would be needed to boil a solvent with dissolved solutes.
Q = mc∆T
m = mass
c = specific heat capacity
∆T = change in temperature
Q = mass x specific heat x change in temperature
Q1 = 1 * 390 * 10 = 3900
Q2 = 1 * 4186 * 10 = 41,860
Q3 = 1 * 840 * 10 = 8,400
Add them all up to get the total energy needed to increase the temperature of the whole set by 10°C.
3900 + 41860 = 45,760
45,760 + 8,400 = 54,160
Therefore, 54,160J is needed to increase the temperature by 10°C.
Answer: Scientists are working on nuclear fusion process. Nuclear fusion is the process in which two atomic nuclei combine to form another nuclei. In the process either energy is absorbed or released due to the difference in the mass of reactants and products.
