Which balanced chemical equation best represents the thermal decomposition of sodium bicarbonate? NaHCO3 (s) → NaOH (s) + CO2 (g) 2NaHCO3 (s) → Na2CO3 (s) + CO2 (g) + H2O (g)
2NaHCO3 (s) → Na2O (s) + 2CO2 (g) + H2O (g) NaHCO3 (s) → NaH (s) + CO (g) + O2 (g)

As you can see from the calculations, 2NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g) was the reaction that happened when heating the NaHCO3 because its theoretical mass from the equation is almost exactly the same as the actual mass of the product from the experiment.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
