Answer:
a. NaHCO₃ + HCl → NaCl + H₂O + CO₂
b. 39.14 g is the mass of NaHCO₃ required to produce 20.5 moles of CO₂
Explanation:
A possible reaction for NaHCO₃ to make dioxide is this one, when it reacts with hydrochloric to produce the mentioned gas.
NaHCO₃ + HCl → NaCl + H₂O + CO₂
Ratio in this reaction is 1:1
So 1 mol of baking soda, produce 1 mol of CO₂
Let's calculate the moles
20.5 g CO₂ / 44 g/m = 0.466 moles
This moles of gas came from the same moles of salt.
Molar mass baking soda = 84 g/m
Molar mass . moles = mass
84 g/m . 0.466 moles = 39.14 g

Answer:
a. The longest chain is chosen incorrectly.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to firstly draw the structural formula of the 1,3-Dimethylbutane:
Thus, we can see that the correct name should be 3-methylpentane since the longest chain was chosen incorrectly, as it must have five carbon atoms.
Regards!
