What are the three requirements for an effective collision

In order to produce an effective collision, reactant particles must possess some minimum amount of energy.

...

Kinetics and Collision Theory.

1.The reactants must collide with each other.

2.The molecules must have sufficient energy to initiate the reaction (called activation energy).

3.The molecules must have the proper orientation.

explanation:

go away, people want answers, not to hook up

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.
