Rank the species from most to least soluble in water. Ba(NO3)2, Ksp = 4.64×10–3 Cd(OH)2, Ksp = 7.20×10–15 FeCO3, Ksp = 3.13×10–11

The formation of nitrogen trichloride is: N2(g) + 3Cl2(g) ⇌ 2NCl3(g)   ΔH = +232 kJ/mol Which change will decrease the concentration of the product?

What is the process to determine the mass (in grams) of carbon dioxide (CO2, molar mass = 44.01 g/mol) produced from 5.00 g of acetylene (C2H2, molar mass = 26.04 g/mol) and excess oxygen? 2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(l)

What is the theoretical yield (in grams) of iron(III) carbonate that can be produced from 1.72 g of iron(III) nitrate and an excess of sodium carbonate?  The molar mass of iron(III) carbonate, Fe2(CO3)3, is 291.73 g/mol, and the molar mass of iron(III) nitrate, Fe(NO3)3, is 241.88 g/mol. 2Fe(NO3)3(aq) + 3Na2CO3(aq) → Fe2(CO3)3(s) + 6NaNO3(aq)
