One isotope of sodium has 11 protons and 7 neutrons. What is the mass number of this isotope?
Alecsey [184]

The mass number, also known as an atomic mass number or nucleon number, refers to the total number of neutrons and protons (in a combination known as nucleons) in an atomic nucleus. It determines the atomic mass of atoms. However, while calculating the mass number, the small contribution of mass from electrons is ignored.  

Mass number is equal to Number of protons + Number of neutrons  

Mass number = 11 + 7 = 18.  

Hence, the correct answer is 18.

The rate of respiration (how fast you breathe) is determined by which amount of gas in the blood? A.Oxygen b.Nitrogen c.Carbon D
andrey2020 [161]

Answer:

c. Carbon Dioxide

Explanation:

The rate of respiration is determined by the presence of concentration of carbondioxide gas in the blood because in the process of respiration, energy in the form of adenine tri phosphate (ATP) and carbondioxide gas are produced. This ATP is required for performing different activities while carbondioxide gas is a waste product which must be removed from the blood through breathing. If carbondioxide gas is produced quickly so the rate of respiration is also increased in order to remove the gas from the blood.
