Given that the liquid conserves the volume, when it is changed from one container to another, the kinetic molecular theory predicts no change in the velocity of the molecules, which means that the temperature will not change.
Answer: 
Explanation:
Volume of metal = volume of water displaced = (30.0 - 25.0) ml = 5.0 ml
Density of metal = 5.50 g/ml
Mass of metal =
Volume of water = 25.0 ml
Density of metal = 1.0 g/ml
Mass of metal =
As we know that,
![-[m_1\times c_1\times (T_{final}-T_1)]=[m_2\times c_2\times (T_{final}-T_2)]](https://tex.z-dn.net/?f=-%5Bm_1%5Ctimes%20c_1%5Ctimes%20%28T_%7Bfinal%7D-T_1%29%5D%3D%5Bm_2%5Ctimes%20c_2%5Ctimes%20%28T_%7Bfinal%7D-T_2%29%5D)
.................(1)
where,
q = heat absorbed or released
= mass of metal = 27.5 g
= mass of water = 25.0 g
= final temperature = ?
= temperature of metal = 
= temperature of water = 
= specific heat of lead = ?
= specific heat of water= 
Now put all the given values in equation (1), we get
![27.5g\times c_1\times (41.0-153)^0C=[25.0g\times 4.814J/g^0C\times (41.0-25.0)^0C]](https://tex.z-dn.net/?f=27.5g%5Ctimes%20c_1%5Ctimes%20%2841.0-153%29%5E0C%3D%5B25.0g%5Ctimes%204.814J%2Fg%5E0C%5Ctimes%20%2841.0-25.0%29%5E0C%5D)
Thus the specific heat of the unknown metal sample is
Answer:
Option (2) At equilibrium, there is a much higher concentration of products than reactants.
Explanation:
The equilibrium constant for a reaction is simply the ratio of the concentration products raised to their mole ratio divided by the concentration of the reactants raised to their mole ratio.
If the equilibrium constant is close to 1 or 1, it means the concentration of the reactants and products are almost the same. But if the equilibrium constant is large as in the case of the question given above, it means that at equilibrium, the concentration of the products are higher than that of the reactants.
