Cu(NO3)2+Zn(s)>Cu(s)+Zn(NO#)2 is an example of which type of reaction. A) decomposition B) single-displacement C) combustion D) double-displacement

it's filtration, but this is an assumption so my apologies if i got this

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.
