Mr. Helms was admitted to the hospital with chest pain and shortness of breath. He has a history of heart disease. A medical examination and an ECG determined that Mr. Helms had a heart attack resulting in mitral (Left AV) valve failure. This is also called mitral valve prolapse. The prolapse is severe and prevents complete closure of the mitral valve a. How will this affect blood flow through the heart?
b. How would SV change on the right side of the heart and on the left side of the heart? How will this affect CO on each side of the heart?
c. Mr. Helms' breathing was labored. Why might that be?

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
