Sodium hydrogen carbonate decomposes (breaks down) to form sodium carbonate, carbon dioxide, and water. Write a skeleton equation for this reaction. Begin by identifying the reactant(s) and product(s).

The equation is:

2NaHCO₃ →  Na₂CO₃  +  CO₂ + H₂O

Explanation:

We identify the reactant

NaHCO₃ → Sodium bicarbonate

We identify the products:

Na₂CO₃, CO₂ and H₂O

2 moles of sodium bicarbonate decomposes to produce 1 mol of water, carbon dioxide and sodium carbonate

x= 40°

Step-by-step explanation:

here

x°+140°+80°= 180°

or , x°+220°=180

or , x°=220°–180°

•

• • x= 40°
