No reaction will occur when NiCl₂(aq.) is added to a test tube containing Zn(NO₃)₂(aq). As to a reaction to occur between two solutions that most probably undergoes a double displacement reaction , it has to meet the following requirements:
1) Precipitate formation
2) Gas generation
3) formation of a non-dissociating compound
But in the reaction of NiCl₂(aq) with Zn(NO₃)₂(aq), no above requirement is met, so no reaction takes place.
NiCl₂(aq.) + Zn(NO₃)₂(aq). ------>No reaction
Answer:
NH3
Explanation:
NH3 molecules make strong intermolecular H bondings and also because of the increase in the size of atomic radius.
The density of water is about 1.00 g/ml, so 500 ml of water is about 500 g
Answer:
Both A and B will be chemically unreactive
Explanation:
Valence (outermost) electrons. Chemical bonds are formed when an atom does not have a full outermost shell, i.e. there are 7 electrons and 1 more is needed, or there is only 1 electron, which can be transferred to another atom.
