Which statement explains why hydrogen bonds are able to form between water molecules?
Water molecules are polar.
Water molecule atoms have weak atomic bonds..
Water molecules show adhesion.
Water molecules are large.
Answer:
Water molecules are polar.
Explanation:
Hydrogen Bonds - Opposite charges attract one another. The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond.
This bond is very weak. Hydrogen bonds are formed easily when two water molecules come close together, but are easily broken when the water molecules move apart again. They are only a small fraction of the strength of a covalent bond, but, there are a lot of them
The fact that water molecules are POLAR makes it possible for hydrogen bonds to form between them.
HOW IS WATER POLAR?
Water is a chemical compound made up of two hydrogen atoms and one oxygen atom i.e. H2O. The hydrogen atoms are electropositive while the oxygen atom is electronegative. The electronegativity of the oxygen atom allows the positive hydrogen ions to be attracted towards it. This makes water molecules polar. Hydrogen bonds form when hydrogen ions (H+) are attracted to an electronegative ion like 02-, S2- etc. Hence, in the interaction of water molecules, the hydrogen ion of one water molecule gets attracted to the oxygen ion of another water molecule, hence, forming HYDROGEN BOND.In a nutshell, hydrogen bonding is possible in water due to its polariry.

What happened as the mass of the sun increased during the formation of the solar system?
Answer:
The Sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust called a solar nebula about 4.5 billion years ago. Most of the material was pulled toward the center to form our Sun, which accounts for 99.8% of the mass of the entire solar system.

The increase in gravitational pull, which caused the surrounding gas and dust to be pulled towards the center of the developing solar system.
What is the Solar system?As the mass of the sun increased during the formation of the solar system, several important changes occurred. One of the most significant changes was the increase in gravitational pull, which caused the surrounding gas and dust to be pulled towards the center of the developing solar system. As a result, the temperature and pressure at the center increased, eventually reaching a point where nuclear fusion began and the sun became a star.
The increase in mass also had an impact on the orbits of the planets. As the gravitational force of the sun increased, it caused the orbits of the planets to become more stable and circular, rather than elliptical or irregular. This stability allowed the planets to maintain their orbits over billions of years, contributing to the long-term stability of the solar system.
In addition, the increase in mass allowed the sun to retain more of the lighter elements, such as hydrogen and helium, which were abundant in the early solar system. This abundance of lighter elements contributed to the formation of the gas giant planets, such as Jupiter and Saturn, which have massive hydrogen and helium atmospheres.
