It evaporates so the ice cube turns in to water then after words evaporat
The compound Fe(NO2)2 is Iron (II) Nitrite.
Hope I could help :)
As the sand mound grows, the point of maximum sand deposition on the leeward face moves closer to the summit, causing a steepening of the leeward face relative to the windward face. The steepening and growing dune now forces wind out over the top of the dune rather than down the leeward face.

The completed question is below
Which pair of molecules is expected to have the most different properties?
CO and NO
SO₂ and CH₄
The correct answer is SO₂ and CH₄
Explanation:
All the four substances are gases at room temperature.
Carbon monoxide (CO) and nitric oxide (NO) are both reactive oxides. They are both polar and inorganic also, hence should have some similar properties (based on there origin/composition and polarity).
Sulphur dioxide (SO₂) is polar because it's a bent molecule, methane (CH₄) is non-polar because of the tetrahedral shape of it's molecule. Methane is an organic molecule while sulphur dioxide is an inorganic molecule.
From the above, <u>it can be deduced that SO₂ and CH₄ are expected to have different properties</u>. For example, the polarity of SO₂ makes it dissolve in water to form an acidic solution while methane does not dissolve in water and hence doesn't form an acidic solution.
