Write balanced chemical equations for the following reactions. boron oxide → boron + oxygen

Over coffee and croissants at breakfast one day, your friend Lena (an expert chemist) says this: "Group 1A metal hydrides react with water to produce hydroxides and hydrogen gas." Using Lena's statement, and what you already know about chemistry, predict the products of the following reaction. Be sure your chemical equation is balanced!   NaH(s) + H2O(l) ->

Looking up one snowy afternoon from a book titled The Moral Case Against Turning Lead Into Gold (Or Vice Versa), your friend Maria (an expert chemist) says this: "Metal sulfides roasted with oxygen produce the corresponding oxide and sulfur dioxide gas." Using Maria's statement, and what you already know about chemistry, predict the products of the following reaction. Be sure your chemical equation is balanced! NiS (s) + O₂(g) → 0-0 0+0 X 00 NO REACTION S

When 1.848 g of finely divided magnesium is burned, 3.080 g of a white oxide is obtained. Determine the empirical formula of the oxide. At mass of Mg= 24g/mole and O= 16g/mole
