Please answer as many as you can! I will ask the teacher but i want as many ideas as I can get and things may actually fall in place!! thanks for your help! xoxoxo

Answer 1

1- covalent bond (nonpolar)

2-no , because the 2 chlorine atoms  have the same electronegativity .so its nonpolar.. --->any covalent bond between same atoms its nonpolar

3-these substances called Ionic Compounds. the properties

4-positive ions on the left , negitive ions on the right

5- Ca3(PO3)2  = 3Ca2+   &   2 (PO3)3-

6- acid-base reaction
