Sugar is considered an organic compound,
Because it is made up a long chain of carbon atoms.
The answer is NO. During combustion of hydrogen, water is produced as an end product. The chemical formulae for combustion of hydrogen are:
2H2 + O2 -->2 H2O
another advantage is that the whole of the fuel load is combusted hence little wastage. This has made the fuel advantageous in its use as rocket fuel since there is no baggage fuel.

the average kinetic energy of all the atoms or molecules of that substance.
Answer:
They all react with acids.
Explanation:
Thus, they decrease the concentration of stomach acid and provide heartburn relief.
The equations for the reactions are:
- Mg(OH)₂ + 2HCl ⟶ MgCl₂ + 2H₂O
- Al(OH)₃ + 3HCl ⟶ AlCl₃ + 3H₂O
- CaCO₃ +2HCl ⟶ CaCl₂ + H₂O + CO₂
