Answer:
H-Cl is a polar bond.
Explanation:
a polar bond is when 2 different elements share the same electrons except one is negative charge and the other is positive.
Cl is a negative charge while H gives off a positive charge, these are also the only one that have 2 different elements.
Answer:
B. Ionic bond
Explanation:
<u>Covalent bond</u> is the bond which is formed with the sharing of the electrons between the two atoms which are taking place in the bond. It is generally formed between the atoms with similar electronegativity values.
<u>Ionic bond</u> is the bond which is formed between the two oppositely charged ions and are held by the strong electrostatic attraction. This is formed between the atoms which have high differing electronegativities.
<u>In this kind of bond, the metal transfers one or more electron to the non metal which gain this electron and forms ionic bond.</u>
<u>Metallic bond</u> is the bond which is formed by electrostatic attraction force between the positively charged metal ions and the conduction electrons.
<u>Hydrogen bonding</u> is a special type of the dipole-dipole interaction and it occurs between hydrogen atom that is bonded to highly electronegative atom which is either fluorine, oxygen or nitrogen atom.
Partially positive end of the hydrogen atom is attracted to partially negative end of these atoms which is present in another molecule. It is strong force of attraction between the molecules.
Humid air has higher pressure because of the heaviness of water humid air is lighter so it has lower pressure.
Answer: a substance made by mixing other substances together.
