<span>The question said,'Emma extracted some fresh orange juice and mixed it with some water. The result was a cloudy yellow colour solution. When poured through a filter, tiny bits of orange were filtered out. What type of mixture did Emma prepare. The correct option is 'suspension'. This is because, suspension is defined as a heterogenous solution in which the solid particle can not dissolve in the solution but can only be removed by filteration. Colloid is wrong because, it can not be filtered as it is homogenous in nature.</span>

Ionic and covalent bonds are intramolecular bonds, meaning that they exist inside the molecule. These bonds deal with the exchange of electrons.
Hydrogen bonds are intermolecular bonds, meaning they bond two separate molecules. These bonds deal with the attraction between hydrogen and electronegative elements such as O and F.
Covalent bond: bond in which one or more pairs of electrons are shared by two atoms. Ionic bond: bond in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other. Other types of bonds include metallic bonds and hydrogen bonding.
Ionic vs covalent
Ionic bonds form between a metal and a non-metal. In these bonds, the electrons from the metal are donated to the non-metal.
Covalent bonds form between two non-metals. In these bonds, electrons are shared between the two atoms.
