24.305 g +28.08 g + 3(15.999 g)=100.382
219 g MgSIO3 (1 mole MGSIO3/100.382g)=2.181 mol MgSIO3
the answer is 2.18 mol MgSIO3
Answer:
In talc preparation, it is used during the filtration process and also acts as a distribution agent. When it is added to the dill water, it combines with all other compounds present in the substance and leaves the water alone. In this way, it acts as a filtering agent.

Answer:
The heat of reaction -1.9 kilo Joules.
Explanation:
Volume of the hydrogen peroxide solution = 50.0 mL
Volume of the ferric nitrate solution = 10.0 mL
Total volume of the solution = 50.0 mL + 10.0 mL = 60.0 mL
Mass of the final solution = m
Density of water = density of the final solution = d = 1 g/mL


Heat capacity of the mixture = c = 4.18 J/g°C
Change in temperature of the mixture = ΔT = 7.47°C
Heat absorbed by the mixture = Q


Heat release due to reaction = -Q'
-Q' =Q (law of conservation of enrage)
Q'= -Q = -1.9 kJ
The heat of reaction -1.9 kilo Joules.
