Answer:
The formula of the compound is Cu₂O.
Explanation:
From the question given above, the following data were obtained:
Mass of compound = 12.5 g
Mass of copper (Cu) = 11.1 g
Mass of oxygen (O) = 1.4 g
Formula of compound =?
The formula of the compound can be obtained as follow:
Cu = 11.1 g
O = 1.4 g
Divide by their molar mass
Cu = 11.1 / 63.5 = 0.175
O = 1.4 / 16 = 0.0875
Divide by the smallest
Cu = 0.175 / 0.0875 = 2
O = 0.0875 / 0.0875 = 1
Therefore, the formula of the compound is Cu₂O.
Sublevel 2s and 2p contains the valence electrons for nitrogen.
Answer:
Oxidation states are used in chemistry solutions. It is a bond in which electron transfers easily from one nucleus to another nucleus.
Explanation:
- Oxidation-reduction reactions have some rules.
- The oxidation state is 0 at an uncombined bond.
- The bond of oxidation reduction is +1 in alkeli metal.
- The bond in two metal is +2
- The oxidation reduction state at helogens is -1. It does not happened always.
- The oxygen bond in oxidation and reduction is -2.
- The sum of the oxidation state is equal to the compound charges.
- In this process the changes occur for any elements. Redox could be occur. Its oxidized and reduction reaction can be seen in this process.
Answer:
