If you dont know dont answer please

Covalent bonds occur between and .
Question 1 options:

metal and metal

metals and nonmetal

nonmetal and nonmetal

What is happens in a neutralization reaction?
Question 2 options:

Acid and base results in salt and water that are neutral pH

Protons balance electrons

Nothing happens

pH of 7 makes everything it touches turn neutral

What is the correct name of the following covalent compound: C2H6. Follow the correct naming rules we learned in class!
Question 3 options:

dicarbon hexahydride

carbon hydride

carbon hydrogen

ethane

What is the correct name of the following ionic compound: CaO. Follow the correct naming rules we learned in class!
Question 4 options:

oxocalcium

monocalcium monoxide

calcium oxygen

calcium oxide

1. Covalent bonds occur between nonmetal and nonmetal.

2. In a neutralization reaction, the acid and base results in salt and water that are neutral in pH

3. C2H6 is ethane!

4.  The correct name of CaO is oxocalcium

I'm glad to help, but please still try to use the naming rules!

Hope this helps :)

ok

explanation:

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.
