Explanation:
A chemical bond which is formed in between positively charged atoms when there is sharing of free electrons in a lattice of cations is known as a metallic bond.
In a pure metal, atoms are surrounded by free moving valence electrons which move from one part of metal to another.
Thus, we can conclude that pure metals are held together by metallic bonds due to attraction between mobile valence electrons and positively charged metal ions.
Synthetic rubber also has shortcomings, the main drawback exists in its tensile effect is relatively poor, tear strength and mechanical properties are relatively poor
Yes, the law of conservation of mass holds.
Explanation:
In every chemical reaction, mass is always conserved. This implies that in chemical reaction, the process proceeds maintaining the same set of atom in the same proportion without new ones forming.
- From the description given, decomposition of the Silver carbonate will produce a silver residue with the given mass.
- The other mass that seems lost can be examined to be given off as carbon dioxide gas which is the other product of the reaction and oxygen.
- Therefore, since the products are silver, carbon dioxide and oxygen, the remaining mass is that of the carbon dioxide and oxygen. It is not lost.
