A polyatomic ion can be found in which of the following choices? a. Sr+2
b. CH3COOH
c. LiBr
d. O3
e. ClO-3

Indeed, most ionic compounds contain polyatomic ions. Well-known examples are sodium hydroxide (NaOH) with OH- as the polyatomic anion, calcium carbonate (CaCO3), and ammonium nitrate (NH4NO3), which contains two polyatomic ions: NH+ and NO3-.

Explanation:

hope it helps

The Answer is e. ClO₅⁻

explanation:

a.   Sr⁺²   is mono ionic with positif charge

b.  CH₃COOH is a neutral molecule, not an ion

c.   LiBr is a neutral molecule, not an ion

d.  O₃ is a neutral molecule, not an ion

e.   ClO₃⁻  is a polyatomic ion

* Polyatomic ion is ion that performed from more that one atom

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
