Answer:
sodium carbonate
Explanation:
Sodium hydrogen carbonate (also known as sodium bicarbonate or bicarbonate of soda) has the chemical formula NaHCO3. When it is heated above about 80°C it begins to break down, forming sodium carbonate, water and carbon dioxide. This type of reaction is called a thermal decomposition.

Answer:
0.185moles
Explanation:
Given parameters:
Volume of O₂ = 49.8L
Unknown:
Number of moles of sucrose required = ?
Solution:
We can assume that the reaction takes place at standard temperature and pressure.
From this, we can find the number of moles of oxygen that reacted and extrapolate to that of sucrose.
Chemical equation;
C₁₂H₂₂0₁₁ + 120₂ → 12CO₂ + 11H₂0
Number moles =
at STP
Number of moles of oxygen gas =
= 2.22moles
12 moles of oxygen gas combines with 1 mole of sucrose
2.22 moles of oxygen gas will combine with
= 0.185moles
Answer :
(a) The overall equation is:

(b) The intermediates are :

Explanation :
<u>Part (a) :</u>
(1)
(fast)
(2)
(slow)
(3)
(fast)
By adding the three equations and cancelling the common terms on both side, we will get the overall equation.

<u>Part (b) :</u>
Intermediates are generated and consumed in the mechanism and do not include in the overall equation.
Since, intermediates will not include in the overall mechanism.
The intermediates are :
