3.953g of egg shell was reacteed with 50ml of 0.1 mol/l hcl and shel contains ca2co3 after all the sheell reacted resultign solution was placed in a columetric flask and th colume made up to be 100ml. 10ml of this reacted exactly with 12.65ml of 0.1 mol/l of naoh.how do u find the mass of ca2co3 in the eggshell
Compute the heat capacity of the calorimeter in J/K assuming that no heat leaks or out of the calorimeter.
Calculate the work (in kJ) when 3.00 moles of hydrogen gas are produced from the reaction of sodium in excess water at 298 K:
If 28 mL of NaCl reacts completely with 46 mL of 0.44 AgNO3, what is the molarity of the NaCl solution? The reaction is: AgNO3 + NaCl = AgCl + NaNO3
Explain why magnetic metals are found only among the 3d and 4f elements. Why are Sc and Ti, which are also 3d elements, diamagnetic?
