Answer:
NBr3 has a trigonal pyramidal geometry where the nitrogen atom is bonded to three bromine atoms and has one lone pairs. The individual bonds are polar, as bromine is less electronegative than nitrogen. The overall compound is also polar, as the dipoles do not cancel.
Explanation:
Answer:
1. Ca(NO3)2 and AgCl3
2. AgCl3
3. Ca(NO3)2
4. a solid that forms out of a solution
Explanation:
1.
3CaCl2 + 2Ag(NO3)3 --> 3Ca(NO3)2 + 2AgCl3
If the American system is the same, group on should be alkali metals and the answer would be frankium
A + BC ---> AB + C
So here one reactant (A) is accepting a group which is being given by another compound (BC) however the A is not giving any group / element or ion
So this single displacement
Similarly in the given reaction
the anion OH- is only being replaced
The element Ca accepts OH- and H2O loses the same group to form new element H2
So the correct answer is
Single replacement also known as single displacement.
