Because if they all agreed their would be no discussion about it and scientists can sometimes be wrong so wouldn't progress as far accurately
Convection is the circular motion of air circulating
Number of protons = 1
Electrons = 1
Neutrons = 0

Hope this helps!
Answer:
253.02 kJ.
Explanation:
The balanced reaction for the decomposition of baking soda is
2 NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g)
We can find the heat of reaction by using the Hess' Law. This is done by using this formula:
∑(Hf,products) -∑(Hf,reactants) = Heat of reaction
where Hf is the heat of formation. According to literature, these are the heats of formation for each of the compounds in the reaction:
NaHCO3: -947.68 kJ/mol
Na2CO3: -1130.94 kJ/mol
CO2: -393.51 kJ/mol
H2O: -241.8 kJ/mol
Applying Hess' Law:
[1(-1130.94) + 1(-241.82)] + 1(-393.51)] - [2(-947.68)] = 129.09 kJ
Thus, the heat of reaction is 129.09 kJ/mol NaHCO3. Since there is 1.96 mol of NaHCO3, the total heat of reaction is 253.02 kJ.
