Bohr o saka mi ad ha piebald webs ldb
Explanation:
Answer = 4.5
Rationale:
the element Mg comes with a 2+ ion and NO3 comes with -1 ion thus 3 * 1.5 M = 4.5 basically look up what mg ion is on google and it says mg+2 and no3 ion no3- im assuming you cant though so look at the formula.
Mg(NO3)2, mg gave 2 to NO3 but where is mg's number? its 1 so 2+1 = 3
* # M = ans
Answer:
C.Echinoderms have radial symmetry and worms have bilateral symmetry
Explanation:
Echinoderms evolved from animals with bilateral symmetry. The larvae of all echinoderms are bilaterally symmetrical but lost during metamorphosis developing into radial symmetry adult. Examples of echinoderms are starfish, sea urchins, sand dollars.
Worms are invertebrate animals having bilateral symmetry. They have a definite anterior (head) end and a posterior (tail) end. Worms have brains that help them detect objects, food, mates, and predators quickly.
C is the answer to the problem
ionic compounds lose or gain electrons to become stable.
ionic compounds are bonds between metals and nonmetals.
molecular or covalent compounds share one or more electrons to become stable.
molecular or covalent compounds are bonds between nonmetals.
