The following equation is not balanced: CaSO4+AlCl3→CaCl2+Al2(SO4) Notice that "SO4" appears in two different places in this chemical equation. SO42 is a polyatomic ioncalled "sulfate." What number should be placed in front of CaSO4CaSO4 to give the same total number of sulfate ions on each side of the equation?

What is the sum of all the coefficients when this equation is balanced with the smallest whole number coefficients. Al(s)+FeO(s)->Fe(s)+Al2O3(s)

Balance the chemical equation below and choose the coefficient for carbon dioxide Al2(CO3)3(s) +Hcl(aq)---> AlCl3(aq)+?CO2(G)+H2O(l)

Balance the following chemical reaction. Enter the sum of the balanced coefficients as your answer. Assign "blank" coefficients a value of 1. potassium metal + solid iodine →potassium iodide

Predict the reactants of this chemical reaction. That is, fill in the left side of the chemical equation. Be sure the equation you submit is balanced. (You can edit both sides of the equation to balance it, if you need to.) Note: you are writing the molecular, and not the net ionic equation. →KClO2(aq)+H2O(l)
