Write a balanced equation for the reactions below. Potassium nitrate and aluminum nitrate
KNO3 + Al(NO3)3 ===>

Calcium hydroxide and iron III chloride
Ca(OH)2 + FeCl3 ===>

Sodium nitrate and magnesium chloride
Na(NO3) + MgCl2 ===>

ITS A BUT THX FOR POINTS

D

Explanation:

c) should be the answer.

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.
