Question

In the "decomposition of baking soda" experiment, you were asked to determine the % baking soda in an unknown mixture of salts by measuring the mass loss
of H₂CO3(g). Which of the following could be a reason for why the mass loss of H₂CO3(g) was a measure of how much baking soda was in the mixture?
The other salts in the mixture had much higher melting points.
All of these could be viable reasons.
The cool flame wasn't hot enough to decompose the other salts.
Baking soda was the only salt in the mixture that contained bicarbonate.
