All oxygen atoms have eight protons, and most have eight neutrons as well. What is the mass number of an oxygen isotope that has
denis-greek [22]

Answer: The mass number of an oxygen isotope that has nine neutrons is 17 and isotope is called as Oxygen-17.

Explanation:

Atomic number is defined as the number of protons or number of electrons that are present in an atom.

For a neutral atom:

Atomic number = Number of electrons = Number of proton

Atomic number= Number of protons = 8

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons

Given: Number of neutrons = 9

Thus mass number = Number of protons + Number of neutrons = 8 + 9 = 17.

Isotopes are elements which have same atomic number but different mass number.

Thus the mass number of an oxygen isotope that has nine neutrons is 17 and isotope is called as Oxygen-17.

Write the chemical formula for a molecule of non cyclic amp.
RSB [31]
The structural formula shown in the picture is the cyclic AMP or cyclic adenosine monophosphate. It is an essential component in RNA synthesis and metabolic processes. When it becomes non-cyclic after enzymatic reaction, you would have to disconnect the cyclic rings. When you do, you add 2 H atoms, one for each terminal end. The formula for cyclic AMP is C₁₀H₁₄N₅O₇P. Since there are three cyclic rings, you would have to add 6 hydrogen atoms. Thus, the formula for noncylic AMP is C₁₀H₂₀N₅O₇P.
