3 Cu + 8 HNO3 = 3 Cu(NO3)2 + 2 NO + 4 H2O i dont know how to explain it but this is the balanced equation basically all the atoms of every element has to be balanced
Answer: An atom has either tendency of accepting or losing electron, on the basis of this virtue it is named as
- Electronegative: An atom has tendency to attract the shared pair of electron towards itself is called electronegative.
- Electropositive: An atom that has tendency to give the shared pair of electron towards an electronegative atom is called electropositive.
For the existence of dipole within a molecule there must be a difference in electronegativity of the atoms participating in it. All the molecules here have dipole moment because the atoms participating in them have a difference in electronegative.
It is because they have different number of valence electrons. Many properties of the element depend on that and as it's different within a period, they don't share many properties
Hope this helps!
Answer:
1.Sn
2.Sn
Explanation:
1. Sn oxidizes to Sn2+
The oxidation number increases from 0 to +2 by removing 2 electrons
Sn ----> Sn²+ & 2e
(Oxidation is the removal of electrons)
2. In a galvanic cell, oxidation takes place at the anode, hence tin is the anode
