Answer: The molality of solution is 0.66 mole/kg
Explanation:
Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.
where,
n = moles of solute
= weight of solvent in g
moles of 
= 
Now put all the given values in the formula of molality, we get
Therefore, the molality of solution is 0.66 mole/kg

Answer:
Chemical bonds are how atoms, and even molecules join together.
Explanation:
There are two main types of primary chemical bonds. While secondary links relate to molecules, primary ties are atom to atom. This answer explains basic primary bonds only.
One must comprehend what a valence shell is before I proceed. The outer electron orbital of an atom is known as the valence shell. Most of the time (except from hydrogen), atoms desire to have 8 electrons in their valence shell, thus they form bonds with other atoms to accomplish this.
<em>All bonds result in a new chemically different molecule. Now, the two types are:</em>
- Covalent: When two atoms combine their electrons to fill their valence shells. The atoms are joined together by this "sharing."
- Ionic: When one atom <em>transfers</em> an electron to another atom in order to fulfill the valence electron requirement. Because electrons have a negative charge, the atom that <em>produced </em>them gains a positive charge as a result of losing its negative charge. The atom that received the electron therefore acquires a negative charge. Because opposing charges attract, it seems sense that the charged atoms bind as a result.
Answer: The scientific method. When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory.
Explanation:
Answer:
Sea breeze moves from the areas of higher pressure on the water in the direction of the areas of lower pressure on land.
Explanation:
Sea breeze moves from the areas of higher pressure on the water in the direction of the areas of lower pressure on land. Whereas, land breeze blows from the areas of higher pressure on land to the areas of lower pressure on water.
