Answer:
Explanation:
Please, find the image with the pictured molecule for this question attached.
The molecule has one oxygen atom (red) covalently bonded to one hydrogen atom (light grey), one nitrogen atom (blue) covalently bonded to two hydrogen atoms (light grey), and two carbon atoms (dark grey) bonded each to two hydrogen atoms (light grey).
<em>Hydrogen bondings</em> are intermolecular bonds (bonds between atoms of two different molecules not between atoms of the same molecule). The hydrogen bonds are attractions between the positive end of one hydrogen atom and the negative end of a small atom of other molecule (N, O, or F).
Since, nitrogen and oxygen are much more electronegative than hydrogen atoms, you conclude that:
- The two hydrogen atoms covalently bonded to the nitrogen atoms have considerably partial positive charge.
- The hydrogen atom covalently bonded to the oxygen atom also has a a relative large partial positive charge.
So, those are three ends of the molecule that can form hydrogen bonds with water molecules.
The hydrogen bondings are only possible when hydrogen is covalently bonded to N, O or F atoms.

Explanation:
For water to be drinkable, it must have sufficiently low levels of dissolved salts and microbes.
There are three rock types in the rock cycle including: igneous, sedimentary, and metamorphic rock.
<u>Explanation:</u>
Any solid or combination of minerals which naturally occurs is understood as a rock. It is classified by the contained minerals, its chemical composition and the manner it is made.
<u>Igneous Rocks:</u> It is generated by magma or lava being refrigerated and solidified. The magma may be produced from partial melting of established rocks, either in the mantle or crust of a planet. The melting is usually caused by one or more of three methods: temperature rise, pressure decrease, or composition transition.
<u>Sedimentary Rocks:</u> These forms that are developed by aggregation or deposition of tiny particles and eventual cementation of mineral or organic substances on the surface of the Earth's ocean floor or other water bodies. Sedimentation is the general term for mechanisms that cause settlement of such particles.
<u>Metamorphic Rocks:</u> These occur from the alteration of different rock types in a technique called metamorphism, which implies change of shape. The initial rock or protolith is heated where temperatures between 150 to 200 ° C and a pressure level of 100 megapascals (1,000 bar) or more induces significant physical or chemical changes.
Answer:
Uranium-238 undergoes alpha decay to form Thorium-234 as daughter product.
Explanation:
Alpha decay is indicative of loss of the equivalents of a helium particle emission. The reaction equation for this reaction is shown below:
→ 
I hope this explanation is clear and explanatory.
