It is also a <em>reduction-oxidation reaction</em> because the <em>oxidation number of N decreases</em> from +5 to +3 and the <em>oxidation number of O increases</em> from -2 to 0.
Answer:
Explanation:
In terms of the size, we can infer from the discussion that the succinic acid will now have a lower size after it has given off the gas. The lower size implies a decrease in the number of atoms that would be contained in the acid. The gas given off has a particular number of atoms it will carry off during its emission.
We can conclude that succinic acid will have more atoms and a larger size compared to the white solid that results from the heating process.
Answer:
From the equation you will see that 1 mol of propane generates 4 mols of water.
Since the molar mass of water
M
(
H2O)=2×1+16=18g/mol
2 mol propane will generate
2
×4×18=144g of water

The chemical warfareagent that attacks primarily the airway and the lungs would be a choking agent. It would cause irritation of the whole respiratory system resulting to dry-land drowning. Examples are chlorine gas, phosgene, acrolein and chloropicrin.
