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

Answer:

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-.

The question is incomplete, the complete question is;

1. Mary and her siblings share similar hair color. Which of these cell components are most involved in determining the hair color of each sibling?

Gene, Chromosome, Nucleus

Cytoplasm, Chloroplasts,Genes

Vacuoles, Nucleus, Chromosomes

Chromosomes, Chloroplasts, Vacuoles

Answer:

Gene, Chromosome, Nucleus

Explanation:

Gene is defined in biology as "a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring" (Oxford Dictionary).

The gene is located in the chromosomes in the nucleus of cells. The sum total of the genes that an organism inherits from its parents is called the organisms' genotype and determines certain features of the organism.

The hair colour of Mary and each of her siblings depends on the genes they received from their parents.

What happens to the composition of an atom to cause it to become positively or negatively charged?

cupoosta [38]

The addition and subtraction of negatively charged electrons can easily change an atom’s charge, because they perpetually spin in valence shells outside the nucleus. It is easier for a neighboring atom to share or steal an electron rather than a positively charged proton, which is found in the nucleus. It requires a strong energy input to split a proton free from other protons and neutrons. thus, the atoms lose or gain electrons from neighboring ones and become what is known as "ions". Hope it helped!
