Cold air mass and warm air mass
Answer:
is an electric force on the potassium ion due to the chloride ion.
Explanation:
Charge on potassium ion =
Charge on chlorine ion =
Separation between these two charges = r =
Electric force on the potassium ion due to the chloride ion = F
Coulomb's law is given as ;
= Charges on both charges
r = distance between the charges
K = Coulomb constant =
(negative sign indicates that attractive force is exerting between two ions)
is an electric force on the potassium ion due to the chloride ion.
2.5 , The reaction is
2K+Cl2=2KCl
Thus the number of moles of potassium and potassium chloride is same
Answer:
Place the reactants in a smaller container.
Explanation:
If you were to reduce the source of heat, the hydrogen and oxygen molecules would lose their kinetic energy, resulting in less collisions.
_______________________________________________________
Maintaining the same temperature of the reactants, the speed would neither increase nor decrease as temperature is directly proportional to the kinetic energy of the molecules, which in turn is directly proportional to the number of collisions. However, placing the reactants in a smaller container would result in less volume, and hence the molecules would collide with one another more often!
