<h2>Answer:</h2>
The correct answer is option C which is,<u> "Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid".</u>
<h3>Explanation:</h3>
- In some conditions, a water droplet remains in the droplet form on the dry surface rather than spreading on the whole surface. It covers only remains on the mall part of the surface and making a dome shape.
- It is due to the fact that the hydrogen bond between the water molecules is much strong than the attraction between the water molecules and surface.
- Hence the option C is correct.
Answer:
Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og). The noble gases are colourless, odourless, tasteless, nonflammable gases. They traditionally have been labeled Group 0 in the periodic table because for decades after their discovery it was believed that they could not bond to other atoms; that is, that their atoms could not combine with those of other elements to form chemical compounds. Their electronic structures and the finding that some of them do indeed form compounds has led to the more appropriate designation, Group 18.

If the magnetic toy trains are opposite charges, they will attract each other and collide however if the trains are of the same charge, they will oppose each other. This is because electrostatic force (the opposite forces so + and -) attract opposite charges
Hope that helps :)
Three. There’s 2 atoms in hydrogen and there’s 1 atom in oxygen.
