Although coal and diamonds are both composed of carbons alone, they differ in their properties because of the bonds present in each substance. Diamonds are composed of covalent bonds which are strong and is crystalline in nature which makes it sturdier. Coal is amorphous which allows the slipping of irregular layers to each other making coal brittle
Answer:
The answer to your question is: [H+] = 0.0016
Explanation:
Data
pH = 2.8
[H+] of the solution = ?
Formula
pH = -log [H+]
process
2.8 = -log [H+] then we get antilog
antilog (-2.8 ) = [H+]
[H+] = 0.0016
<span>The atoms in a compound are held together by a chemical bond. The chemical bonds can be either covalent bonds or ionic bonds. Both the bonds are considered very strong bonds. These bonds are mainly formed by sharing of electrons or in the case when one of the elements making the compound donates electron to the other element. The nucleus of each atom attracts to form a strong bond. This property of attraction between the nucleus of the atoms actually helps in forming the chemical bonds. </span>
Answer:
Reactions occur when two or more molecules interact and the molecules change. Bonds between atoms are broken and created to form new molecules
