In the ionic compound KF, what is the charge on K? positive

partial positive

negative

ООО

partial negative

no charge

Charge on K is +1.

Explanation:

This gives potassium eight valence electrons in its third energy level, and flourine eight valence electrons in its second energy level. This also produces  a potassium cation K+ with +1 charge and a flouride anion F- with -1 charge.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
