  3. Multiply the number of atoms by the atomic weight of each element found in steps 1 and 2 to get the mass of each element in 2HBr: Molar Mass (g/mol) H (Hydrogen) 2 × 1.00794 = 2.01588. Br (Bromine) 2 × 79.904 = 159.808. 4. Sum Each Element's Mass. Finally, add together the total mass of each element to get the molar mass of 2HBr:

  4. 已求解并配平的化学方程式 Br2 + H2 → 2 HBr 具有完整的产物. 请求补充完整产物并配平方程.

  5. In the ion-electron method (also called the half-reaction method), the redox equation is separated into two half-equations - one for oxidation and one for reduction. Each of these half-reactions is balanced separately and then combined to give the balanced redox equation. Step 1. Write down the unbalanced equation ('skeleton equation') of the ...
