Can someone help me with this Nickel metal reacts with silver nitrate solution according to the following balanced equation.
Ni + 2 AgNO3 > 2 Ag + Ni(NO3)2
If 21.4 L of silver nitrate solution reacts with an excess of nickel metal, calculate the mass of silver produced.

The modern periodic table has groups.

An object resting on a table weighs 100 n. with what force is the object pushing on the table? with what force is the table pushing on the object? explain how you got your answer.

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
