1950 g of iron (III) chloride reacted with 1260 g of ammonium hydroxide. 1284 g of iron (III) hydroxide and 1926 g of ammonium chloride were produced. Use these numbers to balance the equation. iron (III) chloride + ammonium hydroxide → iron (III) hydroxide + ammonium chloride FeCl3 + NH4OH → Fe(OH)3 + NH4Cl Ar Fe=56, Ar Cl=35.5, Ar N=14, Ar O=16, Ar H=1
1440 g of aluminium carbide reacted with 2160 g of water. 3120 g of aluminium hydroxide and 480 g of methane were produced. Use these numbers to balance the equation. aluminium carbide + water → aluminium hydroxide + methane Al4C3 + H2O → Al(OH)3 + CH4 Ar Al=27, Ar C=12, Ar H=1, Ar O=16.
2840 g of potassium superoxide reacted with 880 g of carbon dioxide. 2760 g of potassium carbonate and 960 g of oxygen were produced. Use these numbers to balance the equation. potassium superoxide + carbon dioxide → potassium carbonate + oxygen KO2 + CO2 → K2CO3 + O2 Ar K=39, Ar O=16, Ar C=12
1512 g of cyclohexane reacted with 5184 g of oxygen. 4752 g of carbon dioxide and 1944 g of water were produced. Use these numbers to balance the equation. cyclohexane + oxygen → carbon dioxide + water C6H12 + O2 → CO2 + H2O Ar C=12, Ar H=1, Ar O=16
