A 1.446 g sample of calcium sulfate dihydrate is heated, leaving 1.143 g of solid residue. What is the whole number ratio of moles of water to moles of anhydrous salt?

Identify the balanced chemical equation that represents a decomposition reaction. p4 + 3o2 ⟶ p2o3 2fe(oh)3 ⟶ 2feo3 + h2o cuso4 ⟶ cuo + 2so3 2fe(oh)3 ⟶ fe2o3 + 3h2o

In this reaction n2o4(g)→2no2(g) what changes in color would you expect as pressure is increased at a constant temperature
