What method would you use to separate an aqueous solution of lead(ii) and copper(ii) ions

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
