Melting Styrofoam Heads with Acetone!

Styrofoam dissolves in acetone it doesn't actually melt - melting requires heat So the correct question is: Why does acetone dissolve styrofoam? Remember that polystyrene is made up of many smaller molecules called monostyrene The acetone (formula (CH3)2CO) breaks the bonds that hold the polystyrene together And because styrofoam is

Mole Ratios

Mole ratios are used as conversion factors between products and reactants in stoichiometry calculations For example in the reaction 2H₂(g) + O₂(g) → 2H₂O(g) The mole ratio between O₂ and H₂O is #(1 mol O₂)/(2 mol H₂O)# The mole ratio between H₂ and H₂O is #(2 mol H₂)/(2 mol H₂O)# Example: How many moles of O₂ are required to form 5 00 moles of H₂O?
