Answer:
this reaction is a double displacement reaction in which, Aluminium nitrate reacts with hydrogen sulphide to form nitric acid and Aluminium sulphide.
here is the balanced chemical equation for the above reaction :
2 Al (NO3)3 + 3 H2S -> 6 HNO3 + Al2S3
There are 2 Ca, 4 H (2*2) and 4 O (2+2) on the left hand side. So there should be the same number of atoms 2Ca and 4(O+H) on the right hand side. The reaction is a synthesis (making something new), rather than a decomposition (destroying something).
The answer is Two molecules of Ca(OH)2 should be produced during the synthesis reaction.
So technicaly the answer is D
Answer:
See picture for answer
Explanation:
At the beggining, we know that X is a secondary alcohol, with 3 carbons. The only secondary alcohol with 3 carbons, it's the isopropylic alcohol (or 2-propanol). So, in strong acid conditions, we are actually dehidrating the alcohol, to form an alkene, and then it's oxidized to form either a Ketone or aldehyde.
So in picture 1, you have all three compounds, and the mechanism of reaction to form Y.
