adelina 88 [10]

Due to presence of impurities further purification is needed.

A further purification is needed of the final product because of the presence of impurities in the final product. Further purification can also be done in order to gain pure product. There are various ways and methods which can be used for the purification such as Sublimation, Crystallization, Distillation, Differential Extraction and Chromatography.

These methods can be used for further purification and helps in the extraction of pure solution of final product so we can conclude that due to presence of impurities further purification is needed.

Why is matter measured in mass and not weight?​
wel

Answer:

But why should it even <u>matter</u>?

Explanation:

Mass is a measurement of the amount of matter something contains, while Weight is the measurement of the pull of gravity on an object.

The Mass of an object doesn't change when an object's location changes. Weight, on the otherhand does change with location.

g The difference between an ionic bond and a covalent bond is that Select one: a. ionic bonds commonly occur between two metals
Bond [772]

Answer:

C) Covalent bonds come about because of a sharing of electrons; ionic bonds do not.

Explanation:

There are two main types of chemical bonds- covalent and ionic/electrovalent bonds.

Ionic bond: Ionic or electrovalent bonds are characterized by the transfer of electrons from electropositive atoms (metals) to electronegative atoms (non-metals). The metal atoms after donating their electrons become positively charged ions (cations) while the non-metal atoms after accepting electrons become negatively charged ions (anions). Strong electrostatic forces of attraction constitutes ionic bonds.

Covalent bond: Covalent bonds are formed by the sharing of electrons by the atoms involved in the bond; usually between atoms of comparable electronegativities or atoms of the same element. The shared electrons are contributed by each of the atoms involved in the bonding or may be contributed by only one of the atoms. In covalent bonding, molecules rather than ions are formed.
