True, because the large covalent molecules would combine with the others
I believe a solution of Sn(NO3)2 can not be stored in an aluminium container because Aluminium is higher in the reactivity series compared to Tin (Sn). Therefore, Aluminium is more reactive than Tin and hence aluminium will displace Tin from its salt forming Aluminium nitrate and Tin metal. Thus storing Tin nitrate in an aluminium container will cause the "eating away' of the container.
Answer : The energy involved in condensation is, 339 kJ
Explanation :
Formula used :
where,
q = heat required = ?
L = latent heat of vaporization of water = 
m = mass of water = 150 g
Now put all the given values in the above formula, we get:
Therefore, the energy involved in condensation is, 339 kJ
