When you dissolve an antacid tablet in water and it produces bubbles, what kind of change is this? A. a physical change
B. a chemical change
C. a solution change

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.

it's 3.2 on edge, i just took the test.
