Answer: A. It is made of polar molecules.
Explanation:
A polar molecule refers to a molecule that has a covalent bond but has an uneven distribution of electrons due to an atom in the molecule having strong electronegativity which will attract more of the electrons from the other atom.
Water is such a molecule because Oxygen has strong electronegativity which leads to electrons being pulled to it.
Answer:
Explanation:
In a saturated solution, more solute cannot be dissolved at a given temperature.
This is because, the solute dissolves in a solvent because of space between particles of solvent but on continuous addition of solute, the space between the solvent particles gets fulfilled. Thus no more solute particle can dissolve in a solvent.
Answer:
Pasteurization involves heating liquids at high temperatures for short amounts of time, it can make it better if you wanted hot cocoa but bad for milk
Explanation:
Answer:
C-O: polar covalent
Mg-F: ionic
Cl-Cl: nonpolar covalent
Explanation:
Ionic bonds are formed between an atom of a metallic element and another atom of a non-metallic element. Thus, Mg-F is an ionic bond, in which Mg is the metal and F is the nonmetal.
Covalent bonds are formed between two non-metallic elements. So, C-O and Cl-Cl are covalent bonds, because C, O, and Cl are nonmetals.
In C-O, the atom of oxygen (O) has more electronegativity than the atom of carbon (C). Thus, O will attract the electrons with more strength and a difference in charge will be established between the two bonded atoms. So, this covalent bond is polar.
In Cl-Cl, both atoms have the same electronegativity because they are from the same chemical element (Cl). Thus, this bond is nonpolar.
Answer:
A complex ion contains a central metal ion bound to one or more ligands
Explanation:
A complex ion is consists of a central atom or ion, that is usually metallic, called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents.
An example of a complex ion is
[Co(NH3)6]3+
Please go through the attached file for a proper representation of the complex ion.
