Single replacement/displacement

<h3>Further explanation</h3>

Given

Type involves free element

Required

Type of reaction

Solution

Single replacement/displacement occurs when a more active element replaces another less active element in the compound to form a new compound

The activity of this element can be seen from the voltaic series

<em>Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Ag-Pt-Au  </em>

The more to the left, the element is more reactive (easily release electrons) and the stronger reducing agent  

The general formula for single replacement :

A + BC ⇒ AC + B

From this general formula shows that <em>there are 2 free elements</em> on both sides (reactants and products)

Question 18 (Essay Worth 8 points)
DENIUS [597]

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.
