Question 3 what is different between an ionic bond and a covalent bond? an ionic bond is a bond between charged atoms, while a covalent bond is a bond between neutral atoms. an covalent bond is a bond between charged atoms, while an ionic bond is a bond between neutral atoms. an ionic bond shares electrons, while a covalent bond is an attraction between opposite charges. an ionic bond is a bond between charged atoms, while a covalent bond is a bond between opposite charges.

Q) What is different between an ionic bond and a covalent bond?

A) An ionic bond is formed between a metal and a non-metal. ... Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.

Option (a) is the correct answer.

Explanation:

In an ionic bond is defined as the bond formed due to transfer of electron(s) from one atom to another.

An ionic bond will always be formed between a metal and a non-metal.

This is because an atom which loses its valence electrons (metals) acquires a positive charge and another atom which gains the electrons (non-metals) acquires a negative charge.  

Hence, these opposite charges strongly gets attracted towards each other forming a strong bond.

Whereas in a covalent bond, there will be sharing of electrons between the combining atoms.

A covalent bond will always be formed between non-metals when they are present in neutral form.

For example, molecules is formed due to sharing of electrons between the two Cl atoms.

Thus, we can conclude that difference between an ionic bond and a covalent bond is that an ionic bond is a bond between charged atoms, while a covalent bond is a bond between neutral atoms.

explanation:

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
