Answer:
1Na₂S + 1Cd(C₂H₃O₂)₂ → 1CdS + 2NaC₂H₃O
Explanation:
1Na₂S + 1Cd(C₂H₃O₂)₂ → 1CdS + 1NaC₂H₃O₂
1Na₂S + 1Cd(C₂H₃O₂)₂ → 1CdS + 2NaC₂H₃O₂
(on the reactant side there are two molecules of C₂H₃O₂ and 2 atoms of Na, so in order to balance that we put the coefficient 2 on NAC₂H₃O₂)
So the final product is
1Na₂S + 1Cd(C₂H₃O₂)₂ → 1CdS + 2NaC₂H₃O₂
Kinetic energy is converted to potential energy because while it is not actually doing work, it has the potential to do work. If we drop the object from the shelf or release the spring, that potential energy is converted back into kinetic energy.

Answer:
14.512g
Explanation:
Using the expression
mole = Number of molecules/6.022 x 10^23
mole of Fluorine = 2.30 x10^23/6.022 x 10^23
= 0.3819 mol
However,
mole = mass / molarmass
Mass of Fluorine = mole of Fluorine/ Molarmass of Fluorine
Molarmass of Fluorine = 18.998 x 2 = 37.996 g/mol
Mass of Fluorine = 0.3819mol/37.996g/mol
= 14.512g
