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.

The alkali metals, which occupy group 1 of the periodic table. This is because the valence shells of these elements have only 1 electron, so easily form an ionic bond with a non-metal compound by donating this. A cation is formed by this donation, since there is one fewer electron orbiting the nucleus than there is in the atomic form - conversely an anion is formed when an atom gains an extra electron to become negatively charged.
The liquid particles would have moved randomly because of the increase in thermal energy. They would move randomly and would be floating in the bottle moving randomly. The liquid would turn into gas form. Meaning that you would have water particles floating in the bottle moving randomly.
Answer: Areas of high and low pressure are caused by ascending and descending air. As air warms it ascends, leading to low pressure at the surface. As air cools it descends, leading to high pressure at the surface. So it depends on how cold or hot it is. If there is sun and it's very hot the ocean has higher pressure than land. But if it's cold at night then the land has higher pressure then the water
