Answer:
1.5 litre of C5H12 produce 9 litre of water vapour;
Explanation:
First balance the combustion reaction;
→ ![5CO_2 +6H_2O](https://tex.z-dn.net/?f=5CO_2%20%2B6H_2O)
from the balance reacion it is clearly that,
one mole of C5H12 reacts completely with 8 mole of O2 gas;
Hence
one litre of C5H12 reacts completely with 8 litre of O2 gas;
there fore 1.5 litre C5H12 needs 12 litre oxygen gas but we have 15 litre.
so,
C5H12 is a limiing reactant and O2 is a excess reactant.
so quantity of H2O depends on limiting reactant;
one litre of C5H12 produce 6 litre of water vapour;
therefore,
1.5 litre of C5H12 produce 9 litre of water vapour;
Answer:
20 hydrogen atoms
Explanation:
Let us carefully observe the words of the question. We were told that the compound is a hydrocarbon. This implies that it is composed of only hydrogen and carbon.
Secondly, we are informed that the compounds is composed of only C-C single covalent bonds. This means that the compound is an alkane.
Then we are told that it contains nine carbon atoms and is a linear molecule. Hence, the compound must be n-nonane.
Recall that for alkanes, the general molecular formula is CnH2n+2 Substituting n=9 for nonane we have; C9H(2*9)+2 which is C9H20.
Thus there are 20 hydrogen atoms. The structure of the compound is attached to this answer
