Explanation:  Therefore the molecular formula is twice the empirical formula: C2H6O2. The compound dioxane contains only carbon, hydrogen, and oxygen. When 0.956 g dioxane is burned, 1.91 g carbon dioxide and 0.782 g water are formed. In another experiment, it was determined that 6.04x10-3 mol dioxane weighs 0.532 g.

For every 100g : 26.4g of C , 3.3g of H, 70.3 O
find the number of moles: 26.4/12 3.3/1 70.3/16
divide by smallest number: 2.2/2.2 3.3/2.2 4.39375/2.2
the answers are 1 1.5 2
multiply by 2: 2 3 4
so C2H3O4

When a chemical reaction take place new atom or new element are formed true or false
Andreas93 [3]

In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change. A chemical reaction is a mechanism that takes place when two or more molecules interact to produce new products. A reaction between two atoms or ions or molecules may take place and a new bond is formed and no atom is destroyed or created, but reactants form a new substance.
