4. You have knowledge of the outermost electron states of the atoms, trends in the periodic table, and the patterns of chemical properties. Use that knowledge to predict
the products of each of the following equations. Then explain how you made your
predictions. Be sure to balance the equations.

state the principle of separating two immiscible liquids by separating funnel. describe an activity with diagram to separate a mixture of water and kerosene oil. answer: immiscible layers separate out in layers depending on their densities in separating funne

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.
