the other students notice that their hair was starting to stick straight
out. Next they tied a string to their balloons and let them dangle next
to each other. Predict what will happen.
A)
The balloons will separate because friction has given
each an overall negative charge.
B)
The balloons will move together because the
balloons have gained charge from friction.
C)
The balloons will attract each other because one is
positive and the other is negative.
The balloons have each gained positive charge from
D) friction and like charges attract so they will come

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
