Manganese commonly occurs in nature as a mineral. The extraction of manganese from the carbonite mineral rhodochrosite, involves a two-step process. In the first step, manganese (II) carbonate and oxygen react to form manganese (IV) oxide and carbon dioxide: 2 MnCO3(s) + O₂(g) 2 MnO₂ (s) +2 CO₂(g) In the second step, manganese (IV) oxide and aluminum react to form manganese and aluminum oxide: 3 MnO₂(s) +4 Al(s)-3 Mn(s) +2 Al₂O3(s) Write the net chemical equation for the production of manganese from manganese (II) carbonate, oxygen and aluminum. Be sure your equation is balanced. ol 41

Epsom salts, a strong laxative used in veterinary medicine, is a hydrate, which means that a certain number of water molecules are included in the solid structure. The formula for Epsom salts can be written as MgSO4⋅xH2OMgSO4⋅xH2O, where xx indicates the number of moles of H2OH2O per mole of MgSO4MgSO4. When 7.592 gg of this hydrate is heated to 250 ∘C∘C, all the water of hydration is lost, leaving 3.708 gg of MgSO4MgSO4. What is the value of x?
