The coefficient is needed in front of NaNO3 to balance the equation is 2.
<h3>What is balanced equation?</h3>
When in a chemical reaction, both the product elements or compounds should have number of moles equal to that of the elements or compounds of reactants.
In the given chemical reaction equation,
Na2S + Zn(NO3)2 → ZnS + _NaNO3
Number of moles of S is 1 on both the product and reactant side. Zn has 1 mole on both side. NO3 has 2 mole and Na has 2 mole on reactant side. So to balance the equation, Na and NO3 both must have 2 moles on product side.
Thus, the coefficient is needed in front of NaNO3 to balance the equation is 2.

Greater than is the answer. Pulling an equal force provides no acceleration and no movement. Pulling less than would still cause the object to move to the right.
The answer is B hope this helps
