What does Le Châtelier’s principle state?

A. a reaction at equilibrium will respond to balance a charge
B. a reaction will form a new equilibrium ratio when the equilibrium is upset
C. a reaction at equilibrium will go to completion when the equilibrium is upset
D. a reaction at equilibrium will not respond to a change

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

answer: they produce more slow than unicellular organisms.

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.
