Given the unbalanced equation: ___ca(oh)2 + ___(nh4)2so4 → ___caso4 + ___nh3 + ___h2o what is the sum of the coefficients when the equation is completely balanced using the smallest whole-number coefficients?

Respuesta :

McChuck
Ca(OH)2 + (NH4)2SO4 → CaSO4 + 2NH3 + 2H2O

That is the balanced equation.

The coefficients represent the amount of moles for that reactant. There is 1 mole of Calcium Hydroxide, 1 mole of Ammonium Sulfate, 1 mole of Calcium Sulfate, 2 moles of Ammonium, and 2 moles of water.

Now add all the coefficients/moles.

The answer is 7 coefficients.

Answer:

7
